    The Journal of AAPOS, the official publication of the American Association for Pediatric Ophthalmology and Strabismus, publishes clinical and laboratory investigations, current concept reviews, case reports, descriptions of instrumentation and surgical techniques, editorials, and correspondence on topics relevant to pediatric ophthalmology and strabismus. (Authors do not need to be members of the AAPOS, and manuscripts written by AAPOS members are not given preferential consideration.) Text or data previously published in a similar form or extensively reported in "tabloid" ophthalmological publications will not be considered. Questions pertaining to prior or simultaneous publication should be directed to the editor in chief ( before the manuscript is submitted. Review articles, concept reviews (State of the Art), editorials, and AAPOS Workshops are generally submitted by invitation.

    Conflict of interest

    All authors must disclose any financial and personal relationships with other people or organizations that could inappropriately influence (bias) their work. Examples of potential conflicts of interest include employment, consultancies, stock ownership, honoraria, paid expert testimony, patent applications/registrations, and grants or other funding. See also Further information and an example of a Conflict of Interest form can be found at:

    Declarations regarding IRB-HIPAA compliance should appear within the body of the paper. HIPAA should be spelled out e.g., this study was approved by the Institutional Review Board of [name of institution] and conformed to the requirements of the United States Health Insurance Portability and Privacy Act.

    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, 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and tacitly or explicitly by the responsible authorities where the work was carried out, and that, if accepted, it will not be published elsewhere including electronically in the same form, in English or in any other language, without the written consent of the copyright-holder.

    Changes to authorship

    This policy concerns the addition, deletion, or rearrangement of author names in the authorship of accepted manuscripts:
    Before the accepted manuscript is published in an online issue: Requests to add or remove an author, or to rearrange the author names, must be sent to the Journal Manager from the corresponding author of the accepted manuscript and must include: (a) the reason the name should be added or removed, or the author names rearranged and (b) written confirmation (email, fax, letter) from all authors that they agree with the addition, removal or rearrangement. In the case of addition or removal of authors, this includes confirmation from the author being added or removed. Requests that are not sent by the corresponding author will be forwarded by the Journal Manager to the corresponding author, who must follow the procedure as described above. Note that: (1) Journal Managers will inform the Journal Editors of any such requests and (2) publication of the accepted manuscript in an online issue is suspended until authorship has been agreed.
    After the accepted manuscript is published in an online issue: Any requests to add, delete, or rearrange author names in an article published in an online issue will follow the same policies as noted above and result in a corrigendum.


    Upon acceptance of an article, authors will be asked to complete a Journal Publishing Agreement (for more information on this and copyright see Acceptance of the agreement will ensure the widest possible dissemination of information. An e-mail will be sent to the corresponding author confirming receipt of the manuscript together with a Journal Publishing Agreement form or a link to the online version of this agreement.
    Subscribers may reproduce tables of contents or prepare lists of articles including abstracts for internal circulation within their institutions. Permission of the Publisher is required for resale or distribution outside the institution and for all other derivative works, including compilations and translations (please consult If excerpts from other copyrighted works are included, the author(s) must obtain written permission from the copyright owners and credit the source(s) in the article. Elsevier has preprinted forms for use by authors in these cases: please consult

    Retained author rights
    As an author you (or your employer or institution) retain certain rights; for details you are referred to:

    Role of the funding source

    Identify sources of financial support for the research and/or preparation of the article and 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. Please see

    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. To learn more about existing agreements and policies please visit

    Language services

    Please write your text in American English. Authors who feel their manuscript may require editing to eliminate grammatical and spelling errors or stylistic infelicities are encouraged to seek assistance from the English Language Editing service at Elsevier's WebShop Visit our customer support site for more information.

    Informed consent and patient details

    For reports or studies, excluding Short Reports, involving human subjects, a statement must appear early in the Methods section regarding Institutional Review Board (IRB) approval or waiver and when and from whom informed consent was obtained. For North American authors, the statement should indicate the name of the approving committee or body. For studies and reports from the United States, a declaration of compliance with HIPAA regulations should also be included. For studies from other areas, approval by an IRB is strongly encouraged. If IRB approval outside of North America is not available, the authors should confirm that the study and data collection conformed to all local laws and were compliant with the principles of the Declaration of Helsinki (JAMA 2000;284:3043-3045; ). Patients' names, initials, hospital or university numbers, dates and other potentially identifying information should not appear in the manuscript. For studies involving animals, where appropriate, approval by IRB or an equivalent body should be indicated in the Methods section.


    Submission to this journal proceeds totally online and you will be guided stepwise through the creation and uploading of your files. The system automatically converts source files to a single PDF file of the article, which is used in the peer review process. Please note that even though manuscript source files are converted to PDF files at submission for the review process, these source files are needed for further processing after acceptance. All correspondence, including notification of the Editor's decision and requests for revision, takes place by email.

    Submit your article
    All new manuscripts must be submitted in digital form through the Journal of AAPOS online submission and review Web site

    Submission items include (as separate files), in the following order:

    • Cover letter (for specific content of which, see below, "Authors' Responsibility")
    • Signed release forms for identifiable patients
    • Response to reviews (revised manuscripts only)
    • Title page (as a separate file for initial review but integrated into manuscript with revisions)
    • Manuscript (abstract, text, references, and figure legends), including continuous marginal line numbers, or "clean" revised manuscript (with all changes accepted)
    • Highlighted revision, with changes tracked and including continuous marginal line numbers (revised manuscripts only)
    • Tables
    • Figures. Clinical, radiological, and histopathological images should be cropped closely to the point(s) of interest, which may be further indicated by arrows and the like.
    • Video clips or e-supplements

    Each page of the manuscript must include continuous line numbers in the margin. Files should be labeled with appropriate and descriptive file names (eg, Text.doc, Fig1.eps, Table3.doc). Upload text, tables, and graphics as separate files. A ".zip" file ombining all files may also be used. Do not import figures or tables into the text document, and do not upload your text as a PDF file.

    For initial review, a "masked" manuscript is required. Manuscript files, tables, figures, and electronic media should not contain the author's identities in the contents, header/footer, or file names.

    Revised manuscripts must be submitted in two versions: a "clean" version, without highlighting or marginal callouts, and a second, "highlighted" version, with substantive changes tracked. Author name(s), institution(s), or the geographic location of the study masked for initial review may be unmasked in revision. Revised manuscripts must be accompanied by a separate file (distinct from the cover letter) with point-by-point responses to reviewers’ comments and indications of line numbers in the highlighted revision where changed text may be found. Note, it is not acceptable to simply reply to reviewers without also modifying the text accordingly; authors who decline to make a suggested revision must explain their reasoning.

    The publisher and editors regret that they are not able to consider submissions that do not follow these procedures. Authors who are unable to provide electronic files or have other circumstances that prevent online submission may contact the editorial office prior to submission to discuss alternate options.


    Please submit, with the manuscript, the names, addresses and email addresses of at least 2 potential referees. Note that the editor retains the sole right to decide whether or not the suggested reviewers are used.

    If a manuscript is returned to the author for revision, the revised version should be received by the Journal within 2 months. Otherwise, it will be considered a new submission.

    In general, manuscripts should follow AMA Manual of Style (9th ed.) guidelines; technical terminology should reflect Dorland's Illustrated Medical Dictionary (30th ed.). Spelling must conform to U.S. English. Word processing software can assist with this task; in MS Word, for example, choose Tools, then Language, and Set Language: select English (U.S.). See also the Uniform Requirements for Manuscripts Submitted to Biomedical Journals (

    Limit the use of abbreviations to those that are commonly understood without explanation (eg, mm Hg). Do not abbreviate a syndrome or term merely because it appears frequently in the manuscript. Pharmaceuticals should be referred to by the generic name. When brand names of equipment or other products are specified, the manufacturer and city and state of manufacture must be included in parentheses following first mention. Patients should be referred to by case number rather than by name or initials.

    To mask author identity from reviewers, references to the author(s), institution(s), or geographic location(s) by name or initial should be masked from the manuscript until after initial peer review. If authors refer to their own previously published work, they may forgo masking that material. In such cases, authors should identify the issue in question in the cover letter. The editorial office can make a decision about whether or not to mask the material.

    To enable the publisher to use your text files, please follow these instructions carefully. Do not justify the right margin or use centering tabs for text or headers. Be sure to key the letter O, the number 0, the letter l, and the number 1 correctly. Use only one space after colons or periods. Use the default hyphenation of your word processor. Use two hyphens for long dashes. Key in the reference list at the end of the text. Software designed to create references that is used as an adjunct to word processing software (eg, Endnote) may be used, but do not use your word processor's footnote or endnote feature to create such references. When preparing tables, use the table format or use only tabs, not spaces, to align columns. Text to be italicized or set in boldface in print may be keyboarded thus (italics may also be indicated by underlining). Do not input special typesetting codes. The publisher will handle all design considerations for typefaces and page layout.

    Authors should make every effort to present Major Articles as concisely as possible. The Introduction generally need not exceed 2 paragraphs. Methods that require extensive detail may be supplemented with e-components. Discussions should focus on interpretation of the most salient features of the results. There is no need for a summary at the end of the manuscript.

    Literature search
    When making a statement such as "this is, to our knowledge, the first/only report of...," or providing a review of the published literature in a field, authors must demonstrate that they have conducted a comprehensive and systematic review of the literature. Methods of literature search and criteria for including/excluding articles much be stated directly in the manuscript in these cases. This paragraph, which should be placed at the end of the manuscript, before the reference list, under the heading "Literature Search," should state the databases and search terms used, years covered, and additional sources. (eg, articles cited in the reference lists of other articles). It should also indicate how the foreign literature was treated. Other databases such as ExerptaMedica/EMBASE (1947-present), Ophthalmic Literature (1947-1988),and Zentralblatt für die gesamte Ophthalmologie und ihre Grenzgebiete may include key articles that are not cited in MEDLINE.

    Double-masked review
    This journal uses double-masked review, which means that both the reviewer and author name(s) are not allowed to be revealed to one another for a manuscript under review. The identities of the authors are concealed from the reviewers and vice versa. For more information please refer to To facilitate this, please include the following separately:
    Title page (with author details): This should include the title, authors' names and affiliations, and a complete address for the corresponding author including telephone and email address.
    Masked manuscript (no author details): The main body of the paper (including the references, figures, tables and any Acknowledgments) should not include any identifying information, such as the authors' names or affiliations.

    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: Note that source files of figures, tables and text graphics will be required whether or not you embed your figures in the text. 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.


    Major Articles may not exceed 3,000 words in length, not including references. Most manuscripts submitted to the journal do not require encyclopedic referencing; please provide justification in the cover letter during the submission process if more than 25 references are cited. This limitation does not apply to Review articles or AAPOS Workshops.

    Subdivision - unnumbered sections
    Divide your article into clearly defined sections. Each subsection is given a brief heading. Each heading should appear on its own separate line. Subsections should be used as much as possible when cross-referencing text: refer to the subsection by heading as opposed to simply 'the text'.

    State the objectives of the work and provide an adequate background, avoiding a detailed literature survey or a summary of the results.

    Materials and Methods
    Provide sufficient detail to allow the work to be reproduced. Methods already published should be indicated by a reference: only relevant modifications should be described.

    Results should be clear and concise.

    This should explore the significance of the results of the work, not repeat them. A combined Results and Discussion section is often appropriate. Avoid extensive citations and discussion of published literature.

    The main conclusions of the study may be presented in a short Conclusions section, which may stand alone or form a subsection of a Discussion or Results and Discussion section.

    If there is more than one appendix, they should be identified as A, B, etc. Formulae and equations in appendices should be given separate numbering: Eq. (A.1), Eq. (A.2), etc.; in a subsequent appendix, Eq. (B.1) and so on. Similarly for tables and figures: Table A.1; Fig. A.1, etc.

    Essential title page information

    Title page. The title page should include the following elements:

    • Title of the manuscript
    • Each author's name and two highest academic degrees only
    • Author affiliations
    • Corresponding author
    • Institution at which the study was conducted
    • Word count for entire manuscript, including abstract
    • Word count for abstract alone

    The word count for the entire manuscript should include the words in the abstract and body of the manuscript but not the acknowledgments, legends, and references. It should not include the words on the title page itself. The corresponding author's address, telephone number, fax number, and email address should be listed. Authors wishing to receive email communication from readers may have their email addresses printed with the published manuscript. Authors should indicate on the title page whether material was presented at the AAPOS annual meeting or any other national meeting. Any author's financial conflict of interest regarding the subject matter in the manuscript should be disclosed on the title page.


    The abstract must be in the "structured" format and less than 250 words in length. Where appropriate, abstract headings should read: background or purpose; methods; results; and conclusions. See Ann Intern Med 1997;126:36-47 ( ) for more information on structured abstracts. Short reports should not have an abstract but should have an introductory paragraph (in boldface) that summarizes the article.

    Clinical implications

    When you upload your Major Article, you will be required to highlight the clinical implications of your study in fewer than 150 words.


    Ensure consistency of abbreviations throughout the article.


    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 (eg, providing language help, writing assistance or proof reading the article, etc).

    Presentation of data

    Correlation coefficient. When interpreting correlation coefficients, avoid using the terms "significant correlation" or "correlated significantly." A correlation coefficient is concerned with the strength of the relationship between two variables, not merely whether the correlation observed differs significantly from zero. (It is possible, given enough data points, to have a "significant" correlation coefficient of 0.1, which represents a very weak relationship between variables, where one variable influences the other by less than 1%.) Authors are encouraged to calculate and present 95% confidence intervals on the observed and reported correlations (instead of using P values) and to comment on the strength of the correlation as, for example, "strong," "moderate," or "weak."

    Multiple comparisons. Statistical comparisons are generally considered statistically significant when the P value is <0.05, that is, when there is less than a 5% chance that the observed differences are not due to a chance sampling error. When just one test is performed, this is correct; however, when 100 comparisons are performed, we expect that 5% of those (5 comparisons) will falsely appear to be "significantly different." Therefore, when making more than a few statistical comparisons, it is important to perform an additional analysis (for example, the Bonferroni analysis) to refine the desired P value. Statistical consultation may be necessary. For more information, see

    Mean visual acuity. When calculating the mean visual acuity, it is not correct to determine the mathematical average of the decimal equivalent of Snellen acuity. In general, it is important to convert to LogMAR acuity prior to statistical manipulations; it is then possible to convert back to Snellen equivalents after the calculations have been performed. For more information consult the following article: Holladay JT. Visual acuity measurements. J Cataract Refract Surg 2004;30:287-90 (

    Numeric precision. For numeric results, avoid reporting too many digits the precision of a reported value should not exceed what can be justified by the data. For example, a study might report a quotient of 30/93 as 0.3225, implying that the number is known with greater precision and accuracy than is possible with this sample size. In general, the number of digits in the reported value should not exceed the number of digits in the quantity of measurements (eg, for 8 subjects, report one digit of precision, for 80 report two digits of precision, for 800 subjects report three digits of precision). In the example above, the quotient may be reported as 0.32. There are three exceptions to this guideline. First, at least two digits may be reported for percentages (eg, 2 of 6 subjects would be reported as 33%.) Second, when the first digit of a value is 1, an extra digit of precision may be warranted (eg, when reporting the mean refraction of 80 patients, 1.23 D may be preferable to 1.2 D.) Third, it does not make sense to report a value to its true precision if such precision exceeds its clinical significance or measurability (eg, while it may be technically correct to report the mean esotropia of 4,300 patients as 23.59 PD, this degree of precision is neither measurable nor important.)

    Safe and effective. In the U.S. context, the term safe and effective has a specific meaning, having been adopted by the U.S. Food and Drug Administration to indicate that a device or drug has met that agency’s standards and may be sold and marketed in the United States.(For details, consult Albrecht J and Bigby M. The meaning of “safe and effective.” J Am Acad Dermatol 2003;48:144-7.) Published case reports and case series generally cannot establish either safety or effectiveness and the term is thus rarely appropriate. Authors may of course use either term in, say, discussions of complication rates, noting how effectively a procedure met specified goals; furthermore, they may compare this procedure to the complication and effectiveness rates of others. Likewise, statements concerning the relative safety of a procedure in particular contexts may be appropriate. However, general statements concerning a procedure’s "safety" or "effectiveness," while perhaps desirable for rhetorical effect, are in fact meaningless and should be avoided.

    Present simple formulae in the line of normal text where possible and use the solidus (/) instead of a horizontal line for small fractional terms, eg, 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).


    Footnotes should be used sparingly. Number them consecutively throughout the article, using superscript Arabic numbers. Many wordprocessors build footnotes into the text, and this feature may be used. Should this not be the case, indicate the position of footnotes in the text and present the footnotes themselves separately at the end of the article. Do not include footnotes in the Reference list.
    Table footnotes
    Indicate each footnote in a table with a superscript lowercase letter.


    Electronic artwork

    Color artwork
    Please make sure that artwork files are in an acceptable format (TIFF (or JPEG), EPS (or PDF), or MS Office files) and with the correct resolution. If, together with your accepted article, you submit usable color figures then Elsevier will ensure, at no additional charge, that these figures will appear in color on the Web (e.g., ScienceDirect and other sites) regardless of whether or not these illustrations are reproduced in color in the printed version. For color reproduction in print, you will receive information regarding the costs from Elsevier after receipt of your accepted article. Please indicate your preference for color: in print or on the Web only. For further information on the preparation of electronic artwork, please see
    Please note: Because of technical complications which can arise by converting color figures to 'gray scale' (for the printed version should you not opt for color in print) please submit in addition usable black and white versions of all the color illustrations.

    Prices are available on request from Mosby, Inc . Inquiries may be sent to Depending on the priority (assigned by the reviewers) for publishing the illustrations in color, funds may be available from the Journal office to offset some of the cost of color printing. For current funding information, please contact the Journal office. Authors wishing to publish color photographs should state so in their cover letter. Please refer to the section on Authors' Responsibility regarding permission to publish photographs. If an illustration from an article is selected for the cover, it will be published in color at no charge to the authors.

    Illustration services

    Elsevier's WebShop ( 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
    Ensure that each illustration has a caption. Supply captions separately, not attached to the figure. A caption should comprise a brief title (not on the figure itself) and a description of the illustration. Keep text in the illustrations themselves to a minimum but explain all symbols and abbreviations used.


    Number tables consecutively in accordance with their appearance in the text. Place footnotes to tables below the table body and indicate them with superscript lowercase letters. Abbreviations should be resolved in a note. Avoid vertical rules. Be sparing in the use of tables and ensure that the data presented in tables do not duplicate results described elsewhere in the article. Very large tables documenting extensive clinical details are discouraged and will be printed at the discretion of the editor in chief; authors are encouraged to analyze and summarize these data in a concise format. Submit each table as a separate file.


    Citation in text
    Please ensure that every reference cited in the text is also present in the reference list (and vice versa). Any references cited in the abstract must be given in full. Unpublished results and personal communications are not recommended in the reference list, but may be mentioned in the text. If these references are included in the reference list they should follow the standard reference style of the journal and should include a substitution of the publication date with either 'Unpublished results' or 'Personal communication'. Citation of a reference as 'in press' implies that the item has been accepted for publication.

    Reference links
    Increased discoverability of research and high quality peer review are ensured by online links to the sources cited. In order to allow us to create links to abstracting and indexing services, such as Scopus, CrossRef and PubMed, please ensure that data provided in the references are correct. Please note that incorrect surnames, journal/book titles, publication year and pagination may prevent link creation. When copying references, please be careful as they may already contain errors. Use of the DOI is encouraged.

    Web references
    As a minimum, the full URL should be given and the date when the reference was last accessed. Any further information, if known (DOI, author names, dates, reference to a source publication, etc.), should also be given. Web references can be listed separately (eg, after the reference list) under a different heading if desired, or can be included in the reference list.

    References in a special issue
    Please ensure that the words 'this issue' are added to any references in the list (and any citations in the text) to other articles in the same Special Issue.

    Reference style
    References should be numbered consecutively in the manuscript in the order in which they are cited. For model citations, authors may consult the Uniform Requirements for Manuscripts Submitted to Biomedicl Journals (Ann Intern Med 1997: 126:36-47;, noting, however, that the Journal deviates in some respects from formats recommended there as well as in the current edition of AMA Manual of Style.

    For publications by more than six authors, list only the first three, followed by "et al." Titles of books and journals are capitalized but not italicized. Journal titles are abbreviated as in Cumulated Index Medicus. Do not include issue number or month of publication for continuously paginated journals.

    In citations of Web pages and the like, include the following information: Author or name of organization responsible for site. Web page title or organizational name. Date. Web site name. URL. Accessed [date], if pertinent.

    Unpublished data, informal communications, meeting abstracts and the like should be cited parenthetically in the text as concisely as possible rather than in the reference list: include first author, journal abbreviation, volume, and item identifier. For personal communications, the author must provide the Journal's editorial office with a written statement from the cited correspondent granting permission to quote and/or publish privately communicated information.

    Video clips

    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: 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 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 conten

    Supplemental material for online publication

    JAAPOS allows publication of additional tables, figures, or text (eg, methodology, explanations of analysis, spreadsheets with detailed subject data) in the electronic versions of published manuscripts. This material will not be included in print versions, but a reference to its being available online will appear in print versions. Supplemental material is subject to peer review but, once accepted, will be published "as is," without additional editing or formatting. Any supplemental material must be submitted as an "e-component" supplement when the manuscript is first submitted for publication. Authors should indicate in the submitted manuscript that this material is additional information, to be published electronically. The electronic version should not be used as a repository for redundant or unnecessary data.

    Video Articles are high-quality, meticulously produced presentations of advanced operative techniques, examination and diagnostic procedures, and extraordinary cases. Videos are lightly peer reviewed for relevance, overall didactic value, and general production quality. They may combine photographic footage, animation, and cine-image. Voice-over is a prerequisite for acceptance. Accepted articles are streamed at A complete submission comprises the following items:

    • A video of no more than 10 minutes in length and less than 500 MB in a standard file format (eg, MPG, MP4, Apple QuickTime, Microsoft AVI)
    • A voice-over transcript, indicating the start time (min:sec) for each narrative segment
    • A short summary of the article, no more than 400 words, including references
    • A short video clip (about 2 minutes in duration) presenting highlights of the full article. Clips must adhere to Elsevier guidelines for file type, resolution, etc. High-definition video is preferred (720p or greater). On-camera interviews (“talking heads”) should be kept to a minimum.

    Exceptions to the 10-minute maximum will be considered but must be approved by the editor-in-chief in advance of submission.


    This section includes case reports, surgical techniques, description of instrumentation, or small studies of limited scope. Unless otherwise stated, the general requirements for manuscripts outlined above apply to Short Reports.

    Short Reports may not exceed 1,100 words in length (excluding references and figure legends) and should be in the following form: title page, text, references (no more than 10), legends for figures. Instead of a structured abstract, Short Reports must begin with a summary paragraph (up to 200 words), in boldface type, that encapsulates the salient points of the presentation. This paragraph may not contain references and its contents should not be duplicated in the manuscript. Short Reports may have up to 5 illustrations; however, each illustration beyond 3 reduces the text limit by 200 words.

    Case reports should always have the following structure: (1) age of patient; (2) where presented; (3) main complaint; (4) present illness; (5) relevant medical history/review of systems/family history, if any; (6) examination, labs/special studies, or pertinent missing labs; (7) clinical course. Ophthalmological examination results should present data in the following order: (1) visual acuity in each eye, (2) pertinent findings, (3) pertinent negative findings.


    Reviews and AAPOS Workshops are typically submitted by invitation. Prospective authors with an idea for a Review should contact the editor-in-chief prior to submission. Reviews are comprehensive summaries of the literature that present all sides of an issue. Workshops are nearly as comprehensive as Reviews but emphasize practical approaches reflecting the individual preferences of the authors, and include specific recommendations regarding the diagnosis and treatment of highlighted conditions. Reviews and AAPOS Workshops must conform to the guidelines provided for Major Articles, except that the limit of 25 references does apply and, with the editor's approval, the word count may exceed 3,000.


    Correspondence regarding articles that have been published in the Journal should be submitted within 8 weeks of that publication. Letters to the Editor will be considered for publication by the editorial board and may be subject to editing. If a Letter to the Editor is regarding a previous publication in the Journal, the author of that article will be given an opportunity to reply. The letter and response may be published exclusively on the Journal Web site.


    Editorials are typically submitted by invitation; however, prospective authors with an idea for an Editorial should contact the editor-in-chief prior to submission. Editorials should be limited to fewer than 600 words and five references.


    The Journal does not publish notices or other items regarding meetings, honors, or named lectures. These items may be submitted to the AAPOS newsletter, or presented within purchased advertising space. Obituaries relevant to the Journal readership will be considered. Obituaries should be in narrative form and fewer than 100 words.


    The Journal publishes short materials that highlight the human side of medicine. These features are printed within available white space at theend of major articles and may be sent directly to the editor-in-chief ( for consideration. The "Eye on the Arts" feature excerpts passages from novels, poems, or other published works of art that reflect the eyes or the visual system. These excerpts may be submitted directly to the managing editor as PDF files. Include the marked passage, the book cover, and publication information. "Eye on the Arts" contributors are anonymous. The "First Person" feature provides clinicians with an opportunity to share the wealth of emotion that occurs in daily interactions with patients. Contributions might include a humorous comment made by a child or parent, or an event that has touched the life of a family and a physician. In "Clinical Pearls," clinicians share their practical tricks and shortcuts for examination, diagnosis, and treatment. A figure may be included. "First Person" and "Clinical Pearls" contributions should be no more than 200 words. Contributors are acknowledged unless theauthor requests anonymity.

    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):
    When you use a DOI to create links to documents on the web, the DOIs are guaranteed never to change.


    One set of page proofs (as PDF files) will be sent by email to the corresponding author (if we do not have an email address then paper proofs will be sent by post) or, a link will be provided in the email 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 Instructions on how to annotate PDF files will accompany the proofs (also given online). The exact system requirements are given at the Adobe site:
    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 email. 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 email, or by post. 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 send 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.
