Color Atlas of Veterinary Ophthalmology

• Offers a pictorial reference to the clinical appearance of diseases and conditions of the animal eye
• Presents multiple presentations of most ophthalmic diseases to show the varying ways the condition might appear
• Provides more than 1,000 high-quality color clinical photographs showing ocular disorders
• Includes new introductory chapters on ocular anatomy, the ophthalmic exam, and clinical findings in place of the clinical signs chapter
• Covers clinical history, the clinical signs and findings associated with the disease, the rule-outs or differential diagnoses, the recommended treatment, and the prognosis for each disorder
