Vision may not be a dog’s strongest sense, but it still plays an important role in daily life. A dog’s eye health can deteriorate because of aging or disease, so dog owners should be aware of the various eye issues that can occur.
Dr. Lucien Vallone, a clinical assistant professor at the Texas A&M College of Veterinary Medicine & Biomedical Sciences, specializes in ophthalmology and regularly treats eye conditions in dogs.
Vallone said there are three main categories of canine eye problems: diseases of the ocular surface, diseases that cause inflammation within the eye, and glaucoma.
Diseases of the eye’s surface impact the conjunctiva—the mucous membrane over the eye—and the cornea—the clear, protective outer layer of the eye. Vallone said these diseases include inflammation of the cornea, dry eye, and eyelid abnormalities.
The second category is diseases that cause inflammation within the eye, collectively called uveitis.
