Handbook of Veterinary Ocular Emergencies book cover

Handbook of Veterinary Ocular Emergencies

Ocular emergencies can present major problems for vets. Signs can be dramatic, manifesting as apparent instant blindness, severe trauma from fights or road accidents, or the acute discoloration of the white of the eye to red or blue. The vet needs to identify quickly what the problem is so that the immediate palliative measures are appropriate and do not make matters worse.

A major feature of this book is its unique problem-oriented approach, not used in the standard ophthalmology texts. This is complemented by a section arranged on a more anatomical basis, with appropriate cross-referencing, so that access to the right section is made as easy (and quick!) as possible. The book emphasises differential diagnoses and treatment options, showing clearly where the case needs referral to a specialist for resolution. Extra material on background pathogenesis and treatment rationale is provided in boxes. The material needed for the actual emergency will be made readily accessible, using bullet points and easy-to-follow line diagrams.

David Williams is based in the UK. He has recently completed a PhD and is building on an international reputation in both ophthalmology and exotic medicine. His US co-author, Kathie Barrie, is current President of the American College of Veterinary Ophthalmology and a practising vet; she has ensured that the text is of equal relevance to US practice.
