Inherited eye disease in the dog and cat

Abstract

ABSTRACTThis paper describes the more common inherited eye conditions in the dog and cat, paying particular attention to the newer conditions, not all of which have previously been reported in the literature. These newer conditions include entropion in the shar pei, microphthalmos in the dobermann and miniature schnauzer, cataract in the German shepherd dog and Norwegian buhund, progressive retinal atrophy in the Tibetan terrier, Tibetan spaniel, miniature longhaired dachshund and two forms in the Abyssinian cat, multifocal retinal dysplasia in the English springer spaniel and other breeds, persistent hyperplastic primary vitreous in the Staffordshire bull terrier and dobermann and optic nerve hypoplasia in the toy poodle. Anatomical classification presents a convenient means of describing these conditions which may affect the whole globe, the eyelids, the nictitating membrane, the nasolacrimal duct system, the conjunctiva, the cornea, the aqueous, the iris, the lens and zonule, the vitreous, the retina, the choroid and sclera and the optic nerve.
