Animals suffer from eye problems that are similar to those which affect humans. These problems include cataracts, glaucoma, dry eye, corneal ulceration, tumors of the eye, eyelid defects, inflammation of the eye and surrounding tissues, retinal degeneration, and many others. Owners may notice a loss of vision, a change in appearance of the eye, discharge, pain, or a combination of these symptoms. Most cases seen by a veterinary ophthalmologist are referred by a general practice veterinarian. This individual is in the best position to provide an initial examination and determine if a referral to a specialist is indicated.
