Opis: Small Animal Ophthalmic Atlas and Guide - Christine Lim

Small Animal Ophthalmic Atlas and Guide offers fast access to a picture-matching guide to common ophthalmic conditions and key points related to diagnosing and managing these diseases. The first half of the book presents photographs of ophthalmic abnormalities with brief descriptions, as an aid for diagnosis. The second half of the book is devoted to concise, clinically oriented descriptions of disease processes, diagnostic tests, and treatments for each condition. Small Animal Ophthalmic Atlas and Guide is a useful tool for quickly and accurately formulating a diagnosis, diagnostic strategy, and treatment plan for small animal patients.

Ideally suited for use in the fast-paced practice setting, this text provides both reference images and information for managing the disease in a single text. Small Animal Ophthalmic Atlas and Guide is an easy-to-use aid for small animal general practitioners, veterinary students, and veterinary interns seeking a quick yet complete guide to small animal ophthalmology.
