    AUTHOR INQUIRIES


    Welcome to the online submission and editorial system for The American Journal of Ophthalmology. The American Journal of Ophthalmology (AJO) is a peer-reviewed, scientific publication that welcomes the submission of original, previously unpublished manuscripts directed to ophthalmologists and visual science specialists. The manuscripts describe clinical investigations, clinical observations, and clinically relevant laboratory investigations. Published monthly since 1884, the full text of the AJO and supplementary material are also presented on the Internet at AJO.com.

    The AJO publishes Full-Length Articles, Perspectives, Editorials, Correspondence, Book Reports and Announcements. Brief Reports and Case Reports are no longer published.

    Manuscripts are accepted with the understanding that they have not been and will not be published elsewhere substantially in any format, and that there are no ethical concerns with the content or data collection. Authors may be requested to produce the data upon which the manuscript is based and to answer expeditiously any questions about the manuscript or its authors. See AJO policies on redundant publication and access to data.

    FULL-LENGTH ARTICLES

    Full-Length Articles are previously unpublished manuscripts directed to ophthalmologists and visual science specialists. They include clinical investigations, clinical observations, and clinically relevant laboratory investigations.

    Full-Length Articles should, in general, not exceed 7 to 8 single-spaced typewritten pages of manuscript text. References, figure captions, and tables are additional pages that should be used judiciously. Supplemental Material may be provided for the AJO website if a manuscript is accepted. Manuscripts should begin each component on a new page in the following order: (1) title page, (2) text, (3) acknowledgments/disclosure, (4) references, (5) figure captions, (6) tables, (7) figures, (8) contributions to authorship form, (9) ICMJE disclosure form, and (10) permission forms. The abstract should be prepared and submitted as a separate document. Refer to the Checklist when submitting.

    RANDOMIZED CONTROLLED TRIALS

    Manuscripts reporting randomized controlled trials should adhere to the requirements for Manuscript Preparation. In addition, text (which may be up to 10 single-spaced typewritten pages in length) should contain subheadings and information specified in the Consolidated Standards of Reporting Trials (CONSORT) statement. A flow diagram to illustrate the randomization procedure or procedures and numbers and the AJO http://www.consort-statement.org Consolidated Standards of Reporting Trials (CONSORT) Statement Form must be submitted with the manuscript. Authors may decide whether this form will appear in print or only online as Supplemental Material. These requirements follow suggestions published in the Journal of the American Medical Association (JAMA). (Begg C, Cho M, Eastwood S, et al. Improving the quality of reporting of randomized controlled trials: the CONSORT Statement. JAMA 1996;276:637-639).

    PERSPECTIVES

    Invitation-only AJO Perspectives are focused reviews of the evidence supporting the use of a current technique, procedure, therapy, or clinical approach, tempered by the experience and viewpoints of the authors(s). Perspectives should not be a review article. Perspective preparation should follow the guidelines of a Full-Length Article, including a structured abstract of 250 words or less and Table of Contents statement of 75 words or less. The Perspective should be of appropriate length but should not exceed 9 pages of single-spaced typewritten text, 35 references, and 8 figures or equivalent tables. Authors share the cost of color figure reproduction. Perspectives are subject to the standard peer-review process, which is necessary to meet the policies and standard procedures of the AJO.

    Because the essence of a Perspective is selection and interpretation of the literature, the AJO expects that authors of such articles will not have any significant financial interest in a company (or its competitor) that makes a product discussed in the article.

    EDITORIALS

    Editorials provide a forum for interpretive, analytical, or reflective opinions related to manuscripts in the AJO or statements about clinical, scientific, or socioeconomic issues. The invitation-only Editorial should be objective and dispassionate, but is likely to provide alternative points of view and some bias. Editorials should not exceed 1200 words with no more than 15 references. In general, figures and tables should not be used.

    Because the essence of an Editorial is selection and interpretation of the literature, the AJO expects that authors of such articles will not have any significant financial interest in a company (or its competitor) that makes a product discussed in the article. Funding and financial disclosure is required in the Acknowledgments before the references. Editorials do not have an Abstract.

    CORRESPONDENCE

    Letters about recent articles published in the AJO are encouraged and should be submitted through the Elsevier Editorial System within 8 weeks of the article's publication. Correspondence may correct errors, provide support or agreement, or offer different points of view and additional information.

    Correspondence submitted should not exceed 500 words of text and six references. One of the references should be the Article in question.

    Figures and tables are generally not accepted. The AJO does not use the Correspondence section for reporting case reports or short clinical research articles. Correspondence is considered for publication by the Editorial Board and is subject to editing. The authors of articles discussed in the correspondence are given an opportunity to reply in an expedited fashion, adhering to the AJO policy on Responsibility of Authors. If authors do not reply to the correspondence within 14 days, this statement may appear in the AJO print issue in association with the correspondence: "The Authors failed to provide a response to the correspondence in a timely manner." Please provide a complete title page as defined above under Full-Length Article instructions. Financial disclosures should be provided at the end of the correspondence and may be published. (see Acknowledgment section B for information to disclose).

    When appropriate, an effort is made before publication to resolve any controversies between correspondents and the authors of an article.

    ANNOUNCEMENTS

    The AJO offers limited opportunities to announce national or international meetings, symposia, or workshops. Other honors or awards may also be appropriate to announce. The Editor-in-Chief makes the final decision about material to include in the Announcements section of the AJO. Announcements are presented in very brief format in the print publication, with more extensive information at www.AJO.com. Announcements should be sent in digital format by e-mail to the AJO at AJO@Elsevier.com.

    BOOK REVIEWS

    The AJO offers limited opportunity for reviews of ophthalmic books, monographs, or software. Reviews are by invitation only. Publishers or authors are invited to submit this material to the AJO Book Review Editor, Dr David Coats, at the address below:
    6701 Fannin, Suite 610.25
    Houston, TX 77030

    The Book Review Editor will then forward the material to one or more of the AJO's reviewers for evaluation. The Editor-in-Chief makes the final decision as to what material will be published. The reviews are presented in very brief format in the print publication, with more extensive information available at www.AJO.com.

    OBITUARIES

    Obituaries may be offered by readers or requested by the Editor-in-Chief to commemorate the lives of remarkable individuals who are internationally renowned for their contributions to Ophthalmology. The Editor-in-Chief makes the final decision about publishing Obituaries.

    Thomas J. Liesegang, MD, Editor-in-Chief
    American Journal of Ophthalmology
    24517 Deer Trace Drive
    Ponte Vedra, FL 32082

    Ethics in publishing

    For information on Ethics in publishing and Ethical guidelines for journal publication see http://www.elsevier.com/publishingethics and http://www.elsevier.com/journal-authors/ethics.

    Use of animals in biomedical research

    If animals are used in the protocol or the study, the manuscript should describe in the Methods section the animal care protocol that was followed, name the institution that sponsored the study, and identify relevant IRB approval. Biomedical research involving animals must conform to generally accepted principles of animal maintenance and care, such as those of the Association for Research in Vision and Ophthalmology (http://www.arvo.org).

    Conflict of interest in peer-review process and disclosure

    Authors, editors, or reviewers may hold conflicting or competing interests that could result in bias. These conflicts may be real, potential, or perceived. Participants in the peer-review and publication should disclose their conflicting interests, and the information should be made available so that others can judge their effects for themselves.

    Specific manuscripts such as Editorials, Perspectives, or Correspondence by their nature present a biased viewpoint. The Editorial Board and the Editor-in-Chief monitor any conflict of interest.

    The determination of whether a conflict of interest actually exists can be extraordinarily difficult. Recognizing the potential for conflicts of interest is usually easier; they are common, and it is not their existence, but rather their potential to cause bias and failure to acknowledge or recognize conflict, that causes concern.

    Many considerations—intellectual, political, academic, and religious— as well as financial can represent "private interests." The challenge for authors, reviewers, and editors is to recognize the potential for these types of conflicts and respond appropriately. Complete objectivity is not often possible, but fairness and even-handedness can reasonably be expected.

    A key to dealing with conflicts of interest—financial or non-financial—is disclosure. Disclosure of potential financial conflicts of interest is meant to maintain the integrity of professional judgment and to maintain the integrity of professional judgment. A disclosure does not imply that scientists are unduly influenced by financial gain. Rather, disclosure in such cases gives readers the information to allow them to make an informed decision, because it is often difficult to determine when research has been inappropriately influenced by financial gain. Informing readers is the responsibility of the AJO.

    Financial conflicts include salary, consulting fees and honoraria, stock or equity interests, and intellectual property rights (patents, royalties, and copyrights) and sometimes expert witness testimony. The AJO requires authors, reviewers, and editors to declare any financial involvement that they have with commercial entities and some of this information is published in the Acknowledgment section of the article. The AJO does not research or police the possible conflicts of interest. The failure of an author, reviewer, or editor to declare financial interest, however, conflicts with the reader's entitlement to know this potential source of bias.

    Conflicts of interest regarding reviewers or editors include financial issues, but also rivalry, academic scientific and technologic competition, and philosophical values and beliefs.

    Reviewers and editors should indicate any conflicts of interest with regard to a manuscript under review. Reviewers and editors are apt to have conflicts of interest, financial or otherwise, because of their prominent positions. Thus, the existence of a conflict is not really the issue, but rather whether the conflict is sufficient to limit the reviewer's ability to evaluate the manuscript fairly and objectively. AJO reviewers and editors should disqualify themselves if they feel they cannot render fair and objective assessments.

    The Editor-in-Chief is responsible for establishing and maintaining the highest possible standards of the AJO as well as for maintaining the integrity of the AJO itself. The Editor-in-Chief and the Editorial Board are primarily responsible for ensuring a fair review process and should give unbiased consideration to all submitted manuscripts. Editors should not have personal financial involvement in manuscripts they consider for publication.

    Submission declaration

    Submission of an article implies that the work described has not been published previously (except in the form of an abstract or as part of a published lecture or academic thesis or as an electronic preprint, see http://www.elsevier.com/postingpolicy), that it is not under consideration for publication elsewhere, that its publication is approved by all authors and tacitly or explicitly by the responsible authorities where the work was carried out, and that, if accepted, it will not be published elsewhere including electronically in the same form, in English or in any other language, without the written consent of the copyright-holder.

    Defining authorship contributions

    All persons designated as authors should qualify for authorship, and all those who qualify should be listed. Each author should have participated sufficiently in the work to take public responsibility for appropriate portions of the content. One or more authors should take responsibility for the integrity of the work as a whole, from inception to published article.

    Authors must provide a description of what each contributed in the AJO Contributions of Authors and Sponsors form as well as the Acknowledgment Section of the manuscript. The order of authorship on the byline should be a joint decision of the co-authors. Authors should be prepared to explain the order in which authors are listed.

    In multicenter trials, the writing group authors should be listed along with the group name (e.g., Smith TT, Jones JJ, on behalf of the Pediatric Amblyopia Study Group). Other group members should be listed in an appendix before the references.

    Once a manuscript has been submitted, the order of authorship (including adding or removing authors) should not be changed. Exceptions must be approved by the Editor-in-Chief and the Corresponding Author. The Corresponding Author is responsible for assuring that all the involved authors concur with the change.

    Copyright transfer preparation

    After acceptance of a manuscript by the Editorial Board, the publisher, Elsevier, will send to the Corresponding author the forms to complete the transfer of copyright to Elsevier. Do not send copyright transfer forms to the AJO office. Elsevier conforms to the National Institutes of Health and other governmental open access policies.

    Role of the funding source

    You are requested to identify who provided financial support for the conduct of the research and/or preparation of the article and to briefly describe the role of the sponsor(s), if any, in study design; in the collection, analysis and interpretation of data; in the writing of the report; and in the decision to submit the article for publication. If the funding source(s) had no such involvement then this should be stated.

    Funding body agreements and policies

    Elsevier has established agreements and developed policies to allow authors whose articles appear in journals published by Elsevier, to comply with potential manuscript archiving requirements as specified as conditions of their grant awards.

    Language (usage and editing services)

    Please write your text in good American English . Authors who feel their English language manuscript may require editing to eliminate possible grammatical or spelling errors and to conform to correct scientific English may wish to use the English Language Editing service available from Elsevier's WebShop http://webshop.elsevier.com/languageediting/ or visit our customer support site http://support.elsevier.com for more information.

    Informed consent

    When human subjects participate in studies or reports, the authors must state in the Methods section that the study and data accumulation were carried out with approval from the appropriate Institutional Review Board (IRB), Informed Consent for the research was obtained from the patients or subjects, and, for US authors, the study is in accordance with HIPAA regulations. Alternatively, the authors can state that the IRB (name the IRB) waived the need for IRB approval; the authors, however, cannot make the decision that IRB approval was not needed. If waived, the authors must confirm that the study and data accumulation were in conformity with all country, federal, or state laws, informed consent was obtained, and the study was in adherence to the tenets of the Declaration of Helsinki. Do not use patients' names, initials, dates, or hospital numbers, especially in illustrative material. Informed Consent for research requires that the subjects agreed to participate after explanation of the nature and possible consequences of the study. This Informed Consent for Research is distinct from the simple informed consent to perform a procedure or test on a patient.

    Online manuscript submission

    The AJO accepts online submission of manuscripts through Elsevier Editorial System. When a manuscript is submitted online, authors, selected reviewers, editors, and the AJO office can track the progression of the manuscript until a final disposition is made.

    Elsevier Editorial System. can be accessed at ees.elsevier.com/ajo/; alternatively, links to the online submission system are available at AJO.com. On the Elsevier Editorial System front page, click the "Register" link to input your demographics and set up your account. After your registration is complete, a notice will be sent to your e-mail address indicating your user ID and your password. Use this information to log in to Elsevier Editorial System as an author by choosing the "Login" link on the toolbar and select "Submit New Manuscript." Follow the prompts to complete your submission according to the specifications below. Contact the Editorial Office if you have any problems or questions. You may change your password to something more familiar to you, or update any personal information including your e-mail address, at any time by clicking on the Change Details link icon at the top of your screen. Abstract, Disclosure, Contributions of Authors form, Manuscript, Tables, and Figures must be prepared as SEPARATE, individual files; the system requires that each of these files be uploaded separately and blocks incomplete manuscripts from being submitted to the office. Although Elsevier Editorial System presently accepts many file formats for the peer-review process, authors should use only those formats that are acceptable to the publisher, Elsevier, in order to ensure proper publication in the print issues. Please refer to the following individual sections for specific file requirements for text, tables, and figures. Each uploaded file must have a corresponding file extension (such as .doc, .tif). Adherence to the guidelines is essential, and faulty manuscripts will be returned to authors for correction before peer-review or simply rejected.

    If the AJO office uploads a manuscript on behalf of an author, the Corresponding Author will receive an e-mail receipt of the manuscript and related notices regarding the manuscript. Once a manuscript has been uploaded into the system, status updates are available by logging into Corresponding Author's account.

    Submit your article
    Please submit your article via http://ees.elsevier.com/ajo.

    Referees

    Please submit the names and institutional e-mail addresses of several potential referees. For more details, visit our Support site. Note that the editor retains the sole right to decide whether or not the suggested reviewers are used.

    Manuscript review and selection

    Full-Length Articles, Editorials, and Perspectives are peer-reviewed. Only finely polished, publication ready manuscripts should be submitted to the AJO or risk possible rejection prior to peer review. In view of the large and increasing number of manuscripts submitted, the AJO now performs a triage of all submitted manuscripts to determine if they are appropriate and would likely be accepted following peer review. About 50% of manuscripts will be returned to authors because the content is not competitive with current manuscripts because of insufficient new material, repetitive manuscripts, poorly designed or poorly written. This is consistent with the pattern of major medical journals.

    After an initial review of the manuscript, the Editor-in-Chief determines whether the manuscript is appropriate for the AJO and selects an Executive Editor from the Editorial Board who is an expert in the field and who will be responsible for guiding the manuscript through the review process. The Executive Editor then selects several outside reviewers to ensure that at least two reviews are completed. The AJO does not reveal the identity of its reviewers.

    Once these reviews are completed, the Executive Editor critiques and synthesizes the comments of the reviewers, and provides additional Executive Editor's comments to the Editor-in-Chief. The Editor-in-Chief reviews the manuscript together with all comments and makes the publication decision, which is then e-mailed to the Corresponding Author, along with consolidated comments of the reviewers of the manuscript. Because of space constraints in the printed version, only about 20% of submitted Full-Length Articles are accepted. The AJO might not provide complete review of each manuscript but rather enough of a review to determine if acceptable for the AJO.

    General manuscript preparation guidelines

    COVER LETTER

    Manuscripts must be accompanied by a cover letter that should include information on prior or duplicate publication or submission, as well as the originality of the manuscript and any other information that the authors want to convey to the Editor-in-Chief. The authors should indicate whether the manuscript was previously rejected or evaluated in any form by another journal, and they should describe specifically how they have improved the manuscript.

    The principal investigator or the Corresponding Author of a manuscript containing original data must confirm in the cover letter that he or she "had full access to all the data in the study and takes responsibility for the integrity of the data and the accuracy of the data analysis as well as the decision to submit for publication." Cover letters for revised manuscripts must answer, point by point, any concerns noted by reviewers.
    Manuscripts (including title page, abstract, text, references, figure captions, and tables) should be single-spaced on 21.5 x 28 cm (8.5 x 11 in.) pages. One-inch margins should be used on all sides. The right margin should be ragged, not justified.
    STYLE
    Follow guidelines of style, terminology, measurement, and quantitation as set forth in the American Medical Association Manual of Style (10th ed. Oxford University Press, NY, 2007). Arial font size 12 is recommended, as this font causes the fewest problems during conversion to PDF.
    REPORTING VISUAL ACUITY
    The AJO encourages authors to report the visual acuity in the manuscript using the same nomenclature that was used in the study, provided the data was recorded in the Snellen system (using either meters or feet), decimal fraction or logMAR systems. The same visual acuity nomenclature should be presented throughout the manuscript. A Table of Equivalent Visual Acuity Measurements will be provided for the reader in each print issue of AJO. Although standardized reporting of visual acuity would be a better option, it has not yet been accepted by all research groups. The Snellen equivalent in feet should be noted in parentheses next to each visual acuity that is not in the Snellen format, in order to aid readers in the United States.
    STATISTICS
    The AJO requests authors to ensure statistical expertise for a study that has statistical content. Statistical methods must be identified in the manuscript whenever they are used. Software programs used for statistical analyses should be identified so reviewers or readers may verify calculations. When P values are used, the actual P value (for example, P = .032) is preferred to an inequality (for example, P < .05). Reporting basic summary statistics, such as the mean and the standard error, as well as confidence limits, also helps the reader understand the conclusions of the study. Models such as analysis of variance, covariance, multiple regressions, and the like must be specified. A sample size calculation and power analysis should be included when appropriate. Authors should state the levels for alpha and beta errors and the clinically significant difference that was used to determine the power calculation. Numeric equivalents should precede all percentages, as in the following examples: "Of 80 patients, 20 (25%) had retinopathy " or "20 (25%) of 80 patients had retinopathy."

    Use of word processing software

    It is important that the file be saved in the native format of the word processor used. The text should be in single-column format. Keep the layout of the text as simple as possible. Most formatting codes will be removed and replaced on processing the article. In particular, do not use the word processor's options to justify text or to hyphenate words. However, do use bold face, italics, subscripts, superscripts etc. When preparing tables, if you are using a table grid, use only one grid for each individual table and not a grid for each row. If no grid is used, use tabs, not spaces, to align columns. The electronic text should be prepared in a way very similar to that of conventional manuscripts (see also the Guide to Publishing with Elsevier: http://www.elsevier.com/guidepublication). See also the section on Electronic artwork.
    To avoid unnecessary errors you are strongly advised to use the 'spell-check' and 'grammar-check' functions of your word processor.

    Article structure

    Title page

    The manuscript's title should be as brief as possible and no longer than 135 characters and spaces. The title page must include:

    1. The title of the article (informative and concise; avoid questions, declarative sentences, and abbreviations).
    2. The full name of each author and complete address of institutional affiliations. Academic degrees should not be provided.
    3. The name, address, phone number, fax number and e-mail address of the Corresponding Author.
    Once a manuscript has been submitted, the order and number of authors should not change.

    The Corresponding Author will be responsible for all questions about the manuscript and for reprint requests. Only one author can be designated as Corresponding Author; the Corresponding Author need not be the first author on the manuscript. Select a Corresponding Author who will be located at the same address for an extended period in order to respond to post-publication correspondence. Corresponding authors that do not reply in an expeditious manner to all correspondence from AJO both before and after acceptance may be restricted from further submissions to the AJO.

    Number the pages of the manuscript consecutively, beginning with the Title Page as page 1. For Full-Length Articles, the text should, in general, not exceed 8 single-spaced typewritten pages. Please use a spell-checker in addition to careful editing of the manuscript before submission. Authors should not add line numbering as this is automatically added by Elsevier Editorial System.

    Organize and prepare the manuscript to include the following sections:

    Introduction: Describe the purpose of the study, the research rationale, and any major hypothesis that was tested. The Introduction should present the hypothesis and limit references to only the most pertinent previous publications.

    Methods: The first paragraph of the Methods section should describe all the specifics of the study design (see glossary of study designs below) and information about human informed consent or animal care. State whether the IRB approval was prospective (before the study began) or retrospective and indicate precisely what the IRB approved. Name of IRB that approved the research or provide a statement and rationale as to why the named IRB waived approval. Indicate proper informed consent for the treatment and/ or participation in the research, and confirm compliance with HIPAA, Clinical Trials registration (number and location of the registration), Investigational New Drug (IND) or Investigational Device Exemption (IDE) (provide number), and Institutional Animal Care and Use Committee guidelines. If the IRB waived the need for approval of this research or study, then indicate adherence to the Declaration of Helsinki and all federal or state laws in your country. Authors cannot make the decision as to whether IRB approval is needed; your IRB should make that decision and provide a waiver if they feel it does not require IRB approval.

    Methods section should also include setting (multicenter, institutional, or clinical practice); patients and study population (including patient numbers, selection procedures, inclusion/exclusion criteria, randomization, and masking); intervention or observation procedure; and main outcome measure(s). Previously published procedures should be identified by reference only unless they are uncommon to AJO readers. Provide sufficient detail to enable others to duplicate the research. Use standard chemical or nonproprietary pharmaceutical nomenclature. Identify in parentheses specific sources by brand name, company, city, state, and/or country.

    Results: Describe outcomes and measurements in an objective sequence with a minimum of discussion. Tables and figures should be cited in text in sequence. Data should be accompanied by confidence intervals (usually at the 95% interval) and exact P values or other indications of statistical significance.

    Discussion: Elucidate (but do not reiterate) the results, identify any statistically or clinically significant limitations or qualifications of the study, provide responses to other and contradictory literature, and state the conclusions that are directly supported by the data. Excessive generalization and undue speculation should be avoided. Give equal emphasis to positive and negative findings, state whether and what additional study is required, and conclude with the clinical applications or implications supported by the study. The conclusions should be incorporated into the end of the discussion.

    Authors should avoid statements of economic benefits and costs unless their manuscript includes economic data and analyses. Avoid claiming priority (first publication) of the content unless you provide the literature search protocol used. Do not allude to work that has not been completed.

    ACKNOWLEDGMENTS / DISCLOSURE:
    The AJO requires enhanced disclosure information from the authors in a specific format. The following information should appear, in the order indicated (labeled A through E), in the Acknowledgement section of the manuscript (just prior to the References). The information will appear in the print journal. This information should not appear on the Title page of the manuscript or in the Methods section of the manuscript.

    a. Funding/Support (including none): any government and non-government support must be acknowledged. (The authors are reminded that several governments require providing open access to your manuscript.)
    b. Financial Disclosures (including none): The Disclosures should capture the essence of the information contained in the Modified ICMJE Financial Disclosure Form. All disclosures now or in the previous two years that relate to any commercial companies or devices employee, consultant or advisory positions; speaker bureaus, lecture fees; grant support, equity payments; patents; advisor to investment companies; and expert witness testimony. Do not state, "no financial conflicts" as this is not what is requested in this section, but rather all "financial disclosures" are required, and should be consistent with the ICMJE disclosure forms. If you have no financial disclosures, you may state this
    c. Contributions to Authors in each of these areas: design and conduct of the study; collection, management, analysis, and interpretation of the data; and preparation, review, or approval of the manuscript. After each component, provide author initials in parentheses, SAMPLE: Contributions of Authors: Design of the study (AB, CD, EF); Conduct of the study (AB, EF, GH), etc. The AJO adheres to the ICMJE defintion of authorship and authors are requested to review this at: http://www.icmje.org/ethical_1author.html Each author must have a specific role in the manuscript. Overall management/supervision of a laboratory alone or a position of chairmanship alone does not constitute an authorship role. The AJO does not permit guest or honorary authorship.
    d. Other Acknowledgments: Statisticians and medical writers or industry writers might fulfill the criteria for authorship and should be recognized in that role. Otherwise recognize statistical consultation, medical writers or industry writers in the acknowledgment. Include the name and affiliation of the individual. The AJO does not accept manuscripts that do not accurately reflect who wrote the content, ie, the AJO does not permit ghost (hidden) authors. Editorial assistants, photographers, artists, laboratory associates, and others who simply assist in preparation of a manuscript are not to be acknowledged, however valuable their service. The Editor-in-Chief will permit limited exceptions.

    Because readers may infer endorsement of the data and conclusions, all persons must have given permission to be acknowledged and this must be confirmed in the cover letter.

    APPENDIX
    Appendixes should be used sparingly, but they are appropriate to provide survey forms, list the members of a study group, or complex formulas and information. Please note that Supplemental Material for the AJO website may be provided for Full-Length Articles and Perspectives at the time of acceptance.

    Abstract

    Provide a structured abstract of 250 words or less with the following five headings:

    Purpose: State the principal question or objective of the study and the major hypothesis tested, if any.

    Design: Describe the study as retrospective or prospective. Identify the study design. Interventional studies should be listed as a randomized clinical trial, non-randomized clinical trial, or interventional case series (three or more cases). Observational studies should be listed as a case control study, cross-sectional study, cohort study, or observational case series (three or more cases). An experimental study should be listed as an animal study or laboratory investigation. A perspective, meta-analysis, or auto-designation study should be indicated, as appropriate.

    Methods: Use the following subheadings under Methods as appropriate for your study or, alternatively, provide the same information in prose format:

    • Setting: Such as multicenter, institutional, or clinical practice.
    • Patient or Study Population: Including patient numbers (one or both eyes), selection procedures, inclusion/exclusion criteria, randomization procedure, and masking.
    • Intervention or Observation Procedure(s)
    • Main Outcome Measure(s)

    Results: Describe the outcome and measurements, when applicable. Results should be accompanied by data with confidence intervals and the exact level of statistical significance. Results should also identify any significant limitations or qualifications of the data.

    Conclusions: State the conclusions directly supported by the data and describe the clinical applications. Avoid over-generalizations. Give equal emphasis to positive and negative findings, and note specific additional study required.

    Abbreviations

    Restrict abbreviations to those that are widely used and understood by all ophthalmologists. Avoid abbreviations that have meaning only within the context of the specific manuscript. Introduce each abbreviation in parentheses after the first use of the full term in the abstract, in the text, in the figures captions, and in the tables. Système International units and abbreviations of standard measurements, such as mm Hg, cm, and mL, are used without initial expansion. Avoid abbreviations in any titles, headings, or subheadings.

    Acknowledgements

    Collate acknowledgements in a separate section at the end of the article before the references and do not, therefore, include them on the title page, as a footnote to the title or otherwise. List here those individuals who provided help during the research (e.g., providing language help, writing assistance or proof reading the article, etc.).

    Units

    Follow internationally accepted rules and conventions: use the international system of units (SI). If other units are mentioned, please give their equivalent in SI.

    Math formulae

    Present simple formulae in the line of normal text where possible and use the solidus (/) instead of a horizontal line for small fractional terms, e.g., X/Y. In principle, variables are to be presented in italics. Powers of e are often more conveniently denoted by exp. Number consecutively any equations that have to be displayed separately from the text (if referred to explicitly in the text).

    Artwork

    Digital figures
    Digital figures must be uploaded individually into the Elsevier Editorial System according to publication-ready requirements. Figures cannot be embedded in the manuscript text file. Photographic figures should not be in Word, nor are PDFs, Excel files, or PowerPoint slides permitted for any figure due to their low native resolution.

    a) AJO Requirements for Publication Quality Digital Figures:
    Digital figures should be of high quality and in one of the following file formats only: TIFF (with LZW compression), JPEG (with "maximum quality" setting), or EPS. Line art and graphs only may be submitted in Word, if they were created in Microsoft Word or Excel.

    Figures must be at least 3.5 inches wide, at least 300 dpi resolution, and a minimum of 1050 pixels wide. NIH guidelines for online figures suggest a minimum of 1500 pixels wide. Individual figure files should not be larger than 12 MB.

    For complex multi-part figures, an additional separate composite photograph may be submitted in Word to indicate placement. However, this file will not be used in publication; therefore, each individual component of the figure should also include any arrows or markings.

    Text on figures should be avoided unless absolutely necessary. Multi-part figures should be named according to location, ie, Top Right, Center, etc., rather than by letter. Any text, arrows, and other symbols should be large enough to remain legible after reduction. All symbols or abbreviations that appear on the figures should be defined in the caption. Arial font at an appropriate size should be used for any text on a figure. PLEASE NOTE: Manuscripts cannot be reviewed until publication-quality figures have been submitted.

    b) Other General Figure Guidelines
    Figures should be cropped to show only significant details. When a patient is identifiable in a photograph, the author(s) must supply the AJO with evidence of the patient's permission to publish the photograph. (The permission must be submitted to the AJO as a scanned document through Elsevier Editorial System.)

    The Editor-in-Chief reserves the right to withdraw a previously accepted manuscript if the author cannot produce high-quality figures in a timely manner to accompany the text.

    Color Artwork
    The authors should use color figures only when necessary. If a manuscript has been submitted and reviewed with color photos, it will be published in color unless the Editor-in-Chief elects otherwise after communication with the Corresponding Author. The Publisher requires authors to pay for color art that appears in their article. The cost for the first color figure is $650, and the cost for every subsequent color figure is $100. Authors will be billed for color figure(s) after the article has been published.

    Illustration services

    Elsevier's WebShop (http://webshop.elsevier.com/illustrationservices) offers Illustration Services to authors preparing to submit a manuscript but concerned about the quality of the images accompanying their article. Elsevier's expert illustrators can produce scientific, technical and medical-style images, as well as a full range of charts, tables and graphs. Image 'polishing' is also available, where our illustrators take your image(s) and improve them to a professional standard. Please visit the website to find out more.

    Figure captions
    All captions should be listed together on a Caption page after the references. Each caption should be numbered consecutively in the text, have a brief title, and contain a complete description of each figure. The brief title should generally name the disease process or study patients that are in the manuscript. The title and caption should contain enough information so that the figure can be understood independently of the manuscript text and as a "stand alone. Use complete sentences for the captions except in the title, and avoid abbreviations. Single figures should not be numbered.

    When multiple-panel figures are submitted, refer to each panel from Top left to Top right, then Bottom left to Bottom right. Do not use lettering (eg, A, B, C, etc) on the figures.

    Example. FIGURE 1. Patient 3 with staphylococcal corneal abscess. (Top left) The patient's cornea is shown preoperatively with the abscess located superior to the visual axis, (Top right) 3 days postoperatively with the corneal transplant well centered and clear, and (Bottom left) 4 months postoperatively with a crystal clear cornea. (Bottom right) The patient, 1 year postoperatively, shows smooth corneal surface with all sutures removed.

    Tables

    Tables take up substantial space in the print journal and should be limited in number. The information in the text and tables should not be duplicative.

    Tables should be numbered consecutively in Arabic numerals by order of citation in the text. Single tables should not be numbered. Each table should have a brief title so that the reader can understand what is being displayed in the table without reference to the text. Each table should be submitted individually and separately from the manuscript text file. The table number and table title should be on the same line at the top of the table. Avoid abbreviations in any titles. All abbreviations within the table and comments about the table should be included in a footnote to the table.

    All tables should be created in a Microsoft Word document using the table tools. Do not format tables as columns or tabs. Do not use picture tools to create tables. Use additional pages when a table does not fit onto one page.

    Footnotes to tables are indicated by superscripted letters a, b, c, etc.

    References

    References should be numbered consecutively in the text and in the reference list. In the text, reference numbers are entered as superscripts. If you use an automated reference numbering software (eg, Endnote or Reference Manager) the linkage must be turned off.

    The references must be verified by the author(s) against the original documents. PubMed offers a useful reference checker at http://www.ncbi.nlm.nih.gov/entrez/query/static/citmatch.html.

    References to journal articles should follow the current AMA format and include:

    1) Authors' surnames and initials (list 6; for more than 6 authors, list the first 3 followed by "et al.")
    2) Title of Article
    3) Italicized Journal name (as abbreviated in PubMed)
    4) Year
    5) Volume number
    6) Issue number
    7) Inclusive page numbers

    References to books should include:
    1) The author or authors
    2) Chapter title (if any)
    3) Editor or editors (if any)
    4) Book title
    5) Edition (other than the first)
    6) City of publication
    7) Publisher
    8) Copyright year
    9) Inclusive pages of the chapter or section cited

    Examples are as follows:
    Journal article: Robinson MR, Reed G, Csaky KG, Polis MA, Whitcup SM. Immune-recovery uveitis in patients with cytomegalovirus retinitis taking highly active antiretroviral therapy. Am J Ophthalmol 2000;130(1):49-56.
    Book: Rootman J, Stewart B, Goldberg RA. Orbital surgery: a conceptual approach. Philadelphia: Lippincott-Raven, 1994:1-394.
    Book chapter: Macsai MS, Mannis MJ, Huntley AC. Acne rosacea. In: Mannis MJ, Macsai MS, Huntley AC, editors. Eye and skin disease. Philadelphia: Lippincott-Raven, 1996:335-341.
    A reference for an article accepted but not yet in print or online, indicate as "forthcoming": van der Hoek L, Pyrc K, Jebbink MF, et al. Identification of a new human coronavirus. Nat Med. (forthcoming).
    A reference for article accepted and pubished online but not yet in print, provide the DOI and the date of online publication (do not use ePub): van der Hoek L, Pyrc K, Jebbink MF, et al. Identification of a new human coronavirus. Nat Med. doi: 10.1038.nm1024. 2012.02.25.

    Unpublished data, such as studies in preparation or submitted for publication, posters, and unpublished abstracts the reader cannot retrieve in a literature search, are to be incorporated parenthetically in the text. The Corresponding Author is to provide authorization for use of this personal communication.

    Association for Research in Vision and Ophthalmology (ARVO) and other abstract references are discouraged. If used, ARVO abstract citations should appear parenthetically within the text, not as bibliographic references, in the exact format recommended by ARVO. Citations should include: (1) name of first author, (2) "IOVS", (3) year, (4) volume number, (5) "ARVO E-Abstract", and (6) program number. Eg., (Roska BM, et al. IOVS 2002;43:ARVO E-Abstract 1415).

    Personal communications should be cited parenthetically in the text, as in this example: (Evans DW, written communication, September 1, 1997). The Corresponding Author should provide authorization for use of this personal communication.

    Internet references
    Internet references should be limited to important Full-Length articles that are not available in print or have been updated on the Internet since initial print publication. If a print reference is available, it should be used. The online reference should be listed with complete information including title and authors with the addition of the URL address and accession date. The URL address and availability must be confirmed again with any revision submission. Because Internet articles frequently are not available at a future date, the authors must make a print copy of the material they are referencing from the Internet, hold it indefinitely, and provide it to the AJO at any time in the future.
    Example: International Committee of Medical Journal Editors. Uniform requirements for manuscripts submitted to biomedical journals. Available at http://www.icmje.org . Accessed November 12, 2006.

    Journal abbreviations source
    Journal names should be abbreviated according to the List of Title Word Abbreviations: http://www.issn.org/services/online-services/access-to-the-ltwa/.

    Video data

    Elsevier accepts video material and animation sequences to support and enhance your scientific research. Authors who have video or animation files that they wish to submit with their article are strongly encouraged to include links to these within the body of the article. This can be done in the same way as a figure or table by referring to the video or animation content and noting in the body text where it should be placed. All submitted files should be properly labeled so that they directly relate to the video file's content. In order to ensure that your video or animation material is directly usable, please provide the files in one of our recommended file formats with a preferred maximum size of 50 MB. Video and animation files supplied will be published online in the electronic version of your article in Elsevier Web products, including ScienceDirect: http://www.sciencedirect.com. Please supply 'stills' with your files: you can choose any frame from the video or animation or make a separate image. These will be used instead of standard icons and will personalize the link to your video data. For more detailed instructions please visit our video instruction pages at http://www.elsevier.com/artworkinstructions. Note: since video and animation cannot be embedded in the print version of the journal, please provide text for both the electronic and the print version for the portions of the article that refer to this content.

    Accepted manuscript/supplemental material

    The AJO also seeks to further enhance recognition for the contributors of the scientific content in the AJO. Therefore, the first author and the senior author (or both authors if there are only two) of accepted manuscripts will be asked to provide a biographic sketch (limited to 75 words) and a digital photo to be placed on the website linked with the online version at www.AJO.com.

    With revision or acceptance of the manuscript, the Corresponding Author may submit Supplemental Material for consideration for posting on the Internet. Appropriate content may include expanded data sets and spreadsheets, additional digitized figures and illustrations, videos, or expanded techniques and methods sections. Supplemental Material must be submitted at the time of revision submission according to specifications, and such material will be edited. When uploading your Supplemental Material on the Attach Files page of Elsevier Editorial System, please choose Miscellaneous Material for all parts and label each part (eg, Supplemental Figure Caption, Supplemental Figure 1, Supplemental Video, etc.). A legend for each Supplemental Figure or Video should be provided. If you are including supplemental material with your submission, please note the following on your manuscript title page, "Supplemental Material available at AJO.com" and also note, at the appropriate location in the manuscript and in parenthesis, (Supplemental Material at AJO.com). The Supplemental Material will be forwarded by the AJO office to Dr Peter Kaiser, the AJO Associate Editor supervising the Supplemental Material at AJO.com.

    For Supplemental Material, the text must be in Microsoft Word format, and the digital audio/visual must adhere to the requirements for figures listed above.

    Checklist for AJO submission

    Below is a checklist of items required by the AJO for evaluation of a submission. These items should be included in each submission. Please be sure that you have thoroughly read the instructions for preparation and submission of your manuscript before submitting it.

    • Cover Letter indicating the manuscript's category (Full-Length Article, Perspective, Editorial, Correspondence)
    AJO Modification of ICMJE Financial Disclosure form for each author (filled out and uploaded).
    Contributions of Authors and Sponsors Form (filled out and uploaded).
    • Permission for figures if there is identifiable material or photograph .
    • One copy of the manuscript, single-spaced and formatted according to the instructions.
    • Title page
    -
    Title
    - Each author's complete name and affiliation. Academic degrees are no longer requested.
    - The complete and correct address, phone number, fax number, and e-mail address of the Corresponding Author.
    • Structured abstract limited to 250 words for Full-Length Articles and Perspectives
    • Acknowledgments section to provide information about funding sources, financial disclosures, and to recognize statistical and other contributors.

    • References
    • Figure Captions
    • Tables
    • Figures (properly formatted and labeled according to the instructions)
    • CONSORT statement for Randomized Controlled Trials (if applicable).

    Revised manuscripts

    Revisions must be returned to the AJO within 1 month to retain revision status; after that time, the Editor-in-Chief may request another cycle of peer-review or reject the manuscript. The Corresponding Author must reply to each point made in the revision request and may state points of disagreement with the reviewer's comments. Please submit revisions in your account under "Submissions Needing Revision" on Elsevier Editorial System with the files prepared according to online manuscript submission guidelines. Please follow the instructions on the Elsevier Editorial System under "Guidelines for Revisions".

    Use of the Digital Object Identifier

    The Digital Object Identifier (DOI) may be used to cite and link to electronic documents. The DOI consists of a unique alpha-numeric character string which is assigned to a document by the publisher upon the initial electronic publication. The assigned DOI never changes. Therefore, it is an ideal medium for citing a document, particularly 'Articles in press' because they have not yet received their full bibliographic information. Example of a correctly given DOI (in URL format; here an article in the journal Physics Letters B):
    http://dx.doi.org/10.1016/j.physletb.2010.09.059
    When you use a DOI to create links to documents on the web, the DOIs are guaranteed never to change.

    Proofs

    One set of page proofs (as PDF files) will be sent by e-mail to the corresponding author or a link will be provided in the e-mail so that authors can download the files themselves. Elsevier now provides authors with PDF proofs which can be annotated; for this you will need to download Adobe Reader version 7 (or higher) available free from http://get.adobe.com/reader. Instructions on how to annotate PDF files will accompany the proofs (also given online). The exact system requirements are given at the Adobe site: http://www.adobe.com/products/reader/tech-specs.html.
    If you do not wish to use the PDF annotations function, you may list the corrections (including replies to the Query Form) and return them to Elsevier in an e-mail. Please list your corrections quoting line number. If, for any reason, this is not possible, then mark the corrections and any other comments (including replies to the Query Form) on a printout of your proof and return by fax, or scan the pages and e-mail. Please use this proof only for checking the typesetting, editing, completeness and correctness of the text, tables and figures. Significant changes to the article as accepted for publication will only be considered at this stage with permission from the Editor. We will do everything possible to get your article published quickly and accurately – please let us have all your corrections within 48 hours. It is important to ensure that all corrections are sent back to us in one communication: please check carefully before replying, as inclusion of any subsequent corrections cannot be guaranteed. Proofreading is solely your responsibility. Note that Elsevier may proceed with the publication of your article if no response is received or may reject your article.

    Publication process

    The Editor-in-Chief accepts the manuscript with the understanding that the authors cooperate in a timely manner with the production process, including any response to future correspondence from the AJO or its readers. The authors are required to provide an edited print-ready version of the manuscript at the final revision stage (or earlier). The Publisher employs copy editors that format the manuscript to AJO style but do not perform extensive editorial copyediting.

    The article will then be processed into page proofs, with all art and tables in place. The Production Editor will send the Corresponding Author a galley proof by e-mail or mail, which should be corrected and returned within 48 hours. Authors must check their proofs very carefully, because approval indicates that all copyediting changes have been accepted unless corrections are returned to the Production Editor. A second proof will not be provided. Authors must also answer any copyediting queries within the proof. Notification of the costs for printing illustrations in color and page charges will be provided at this proofing stage. An order form for the article reprints will be sent to the Corresponding Author before publication. Reprints should be ordered prior to publication.

    Good quality illustrations using the above guidelines must be made available to the printer; the Editor-in-Chief reserves the right to withdraw acceptance at any time if the images do not meet expectations, the authors do not provide them in a timely fashion, or other aspects of the publication process are not diligently followed to the satisfaction of the Editor-in-Chief.

    The authors may participate in scientific programs and presentations providing the highlights of the manuscript but should be aware that the manuscript acceptance will be withdrawn if it is published in substantive content elsewhere in print or electronically prior to the AJO publication, per the Policy on Duplicate Publication. After publication of a manuscript in the AJO, the authors and readers may monitor any future citations of the article by specialized software at AJO.com.

    AJO on the internet

    The AJO Table of Contents and Abstracts for each month are available on the Internet at AJO.com. Forthcoming issue line-ups can also be received through e-mail by signing up for ScienceDirect. The full text of AJO is available online and to recipients of ScienceDirect if they are subscribers to the print edition or if an article has been made open access by the author or funder. Supplemental Material augments Full-Length Articles and Perspectives, and special features present new content on the electronic AJO. Internet Advance offers the manuscripts that have been accepted but not yet printed in the AJO. Book Reviews and Announcements are also listed in the print issue with more complete information available at AJO.com. The website provides a keyword search and an electronic link to abstracts for many of the references in published material. Authors may track any future citations to their AJO printed manuscripts at AJO.com.

    AJO policies

    A. REJECTION BY PREVIOUS JOURNAL
    If the manuscript has been previously rejected or evaluated in any form by another journal, the authors should note that in the cover letter and indicate how they have improved the manuscript.

    B. DUPLICATE PUBLICATION
    To protect the mission of the AJO as a peer-reviewed journal, only original material will be published in the AJO. Authors who distribute e-prints, preprints, reprints, or substantive content in any format, including digital, of an article into the public domain before publication risk losing the opportunity to publish in the AJO. When authors submit material for publication in the AJO, they must claim the copyright and must transmit copyright of their material to the AJO. Publication of the material elsewhere (duplicate publication) without permission of the AJO is a copyright infringement.

    InternetAdvance at AJO.com shows a galley of each article that has been accepted for publication but has not yet appear in print. This permits an article to appear before the print publication without endangering the mission of the peer-reviewed journal.

    C. STATEMENTS OF PRIORITY
    The AJO discourages statements of priority (such as "we are the first to report...") because of the inability to be familiar with all published works or presentations on a subject. Either consider deleting the statement of priority or provide a standard statement that adheres to AJO policy, such as "we are unaware of previous reports of this finding (phenomenon, procedure, or other appropriate wording) and could find no reference to it in a computerized search (include the name of the database, such as PubMed)."

    D. MULTICENTER STUDIES
    The AJO encourages the submission of multicenter studies. On the title page, preferably the writing group authors should be listed along with the group name (eg, Smith TT, Jones JJ, on behalf of the Pediatric Amblyopia Study Group). Other group members should be listed in an appendix before the references. When the study group name alone is listed on the title page, the Copyright Transfer Agreement requires only the original signature of the Corresponding Author.

    E. SUGGESTIONS FOR RESEARCH PRESENTERS AT SCIENTIFIC MEETINGS PRIOR TO PUBLICATION
    The AJO and the scientific community encourage presentation at meetings. Presenters planning to submit information to a peer-reviewed journal, however, should not share their slides, materials, or additional information with newspapers or tabloids before publication. If the presenter is given a preprint of a planned publication by a newspaper or tabloid, the presenter again could ask the writer to withhold the information until after the information has been published in the peer-reviewed literature. Violations could result in public reprimand regarding copyright infringement and may result in a presenter being subjected to greater scrutiny when future materials are considered for publication in the AJO.
    F. CORRECTIONS AND RETRACTIONS
    Errors may be noted in published articles that require the publication of a correction or an erratum. Most corrections are minor. Some errors, however, may negate the value of the initial manuscript. These do not include inadequacies exposed by the emergence of new scientific information, in which case no corrections or withdrawals are needed.

    If substantial doubts arise about the honesty of a work, either submitted or published, it is the Editor-in-Chief's responsibility to ensure that the possible fraud is addressed. It is not usually the task of the Editor-in-Chief to conduct a full investigation or to make a determination; that responsibility lies with the institution where the work was done or with the funding agency. The Editor-in-Chief should be promptly informed of the final decision of the institution involved, and if a fraudulent article has been published, the AJO will print a retraction. If the study was not under the aegis of an IRB or if this method of investigation does not result in a satisfactory conclusion, the Editor-in-Chief may choose to publish an expression of concern with an explanation or a full retraction, following an attempt for clarification from the authors.

    The Editor-in-Chief may ask the authors' institution to assure the AJO of the validity of earlier work published in the AJO or to retract it.

    G . CONFIDENTIALITY
    The Editorial Board and reviewers should respect authors' confidentiality because authors have entrusted the AJO with the results of their scientific work and creative effort. Authors' rights may be violated by disclosure of the confidential details of the review of their manuscript.

    Reviewers also have rights to confidentiality, which must be respected. Editors should not disclose information about manuscripts (including their receipt, their content, their status in the reviewing process, their criticism by reviewers, or their ultimate fate) to anyone other than the authors themselves and reviewers.

    Editors should make clear to their reviewers that manuscripts sent for review are privileged communications and are the private property of the authors. Therefore, reviewers and members of the Editorial Board should respect the authors' rights by not publicly discussing the authors' work or appropriating their ideas before the manuscript is published. Reviewers should not be allowed to make copies of the manuscript for their files and are prohibited from sharing it with others, except with the permission of the editor.

    H. CONDUCT AND COMMUNICATION OF CLINICAL TRIALS
    The AJO recommends that researchers and authors (and commercial companies) adopt and adhere to the Pharmaceutical Research and Manufacturers (PhRMA) "Principles for the Conduct of Clinical Trials and Communication of Clinical Trial Results" listed at the http://www.phrma.org/sites/default/files/pdf/042009_clinical_trial_principles_final.pdf. These principles describe the relationship of PhRMA member companies with others involved in clinical research and set forth the rules companies have volunteered to follow in order to protect the safety of research participants wherever the companies conduct clinical trials. In the principles, the PhRMA companies commit to the timely communication of all meaningful results of clinical trials, whether those results are positive or negative. The principles further state that the results should be communicated in an objective, accurate, balanced, and complete manner.

    I. AJO ACCESS TO SCIENTIFIC DATA
    Thorough peer review by the AJO may require that organizations that sponsor research provide access to data and analyses that are not provided in a submitted manuscript, and sometimes such access is needed after publication as well. The opportunity also exists to post this information on the AJO website as Supplemental Material in association with the published manuscript.

    J. REPORTING NEW MICROBIAL ORGANISMS IN OPHTHALMIC INFECTIONS
    The AJO is interested in confirming that certain organisms participate in ocular disease. The text must provide adequate laboratory information that can substantiate the microbial identification. This requires that any unusual pathogen be confirmed by two different methods or at two independent laboratories. The journal Cornea initiated this confirmatory policy (Wilhelmus KR. New corneal infections: preventing a crisis of identity. Cornea 2003;22:95-96).

    K. CANCER CLASSIFICATION SCHEME
    Authors should use the American Joint Commission on Cancer classification scheme when describing patients with ophthalmic malignancies; see American Joint Committee on Cancer.ACC Cancer Staging Manual, Seventh Edition, Springer, New York.

    L. OCULAR TRAUMA TERMINOLOGY
    It is suggested that the terminology used in descriptions of ocular trauma should conform to the recommendations of the United States Eye Injury Registry and the International Society of Ocular Trauma (Birmingham Eye Trauma Terminology [BETT], Kuhn F, Morris R, Witherspoon D, et al. A standardized classification of ocular trauma. Ophthalmology 1996;103:240-243).

    M. CLINICAL TRIALS REGISTRATION
    The AJO requires that human clinical trials are registered before enrollment in order for the results to be published in the AJO. See Arch Ophthalmol 2005:123:1263-1264 for complete statement. Phase III trials should be registered as well as many phase II trials. Most phase I trials do not need to be registered. The Methods section should contain a statement about where the registration information is available to the public. Satisfactory public databases include the National Institute of Health maintained site at http://www.clinicaltrials.gov (for either NIH or non-NIH sponsored studies) or the International Standard Randomized Controlled Trials at http://www.controlled-trials.com.

    N. STANDARDIZED GRAPHS AND TERMS FOR REFRACTIVE SURGERY RESULTS
    The AJO prefers the use of standardized graphs and terms in displaying refractive surgery results in order to permit an easier and evident comparison among comparative studies in the literature. See: Stulting RD, Dupps WJ Jr, Kohnen T, Mamaluis N, Rosen ES, Koch DD, Obstbaum SA, Waring GO 3rd, Reinstein DZ. Standardized graphs and terms for referactive surgery results. Cornea. 2011:30(8):945-947.

    Glossary of study designs

    Randomized Clinical Trial: A human trial involving at least one experimental treatment group and one control treatment group, concurrent enrollment, and follow-up of the experimental and control groups with assignment to experimental and control groups by a randomization process. Persons responsible for treatment and subjects are not able to influence the treatment assignment, and assignment remains unknown to the staff and subjects until eligibility has been determined.

    Nonrandomized Clinical Trial: A human trial involving at least one experimental treatment group and one control group, concurrent enrollment, and follow-up of the treatment and control groups. Assignment to experimental control groups is by a process other than randomization.

    Interventional Case Series: Three or more cases, which may or may not be consecutive, that describe the outcome of an intervention without a control group for comparison.

    Cohort Study: A longitudinal observational study that includes subjects with identifying characteristics and involves measurements or observations on more than one occasion.

    Case-control Study: An observational, and usually retrospective, study of subjects with identifying characteristics and a disease or abnormality (cases) for comparison to subjects with similar characteristics, but without the disease or abnormality (controls). Comparison proceeds from effect to cause and generally yields odds ratio (usually an approximation of relative risk).

    Cross-sectional Study: An observational study that identifies subjects with and without the disease or abnormality being studied at the same time. Study yields prevalence data and may or may not be population based.

    Observational Case Series: Three or more cases in which natural history of the disease or abnormality is described. Cases may be collected and studied retrospectively or prospectively over any time frame.

    Experimental Study: Animal or laboratory research describing observations, surgical or medical interventions, testing, or devices. Experimental studies are generally prospective and utilize a protocol in which controls are included.

    Meta-analysis of Literature: Analysis of literature using statistical methods to integrate and summarize several studies.
