Progressive retinal atrophy

From Dog

Progressive retinal atrophy is a common autosomal-recessive genetic ocular disease of dogs characterized by visual deficits from a young age.

This disease has a number of underlying genotypic mutations characterized by varying clinical presentations, including:

Affected dogs usually present with variable visual deficits from mild vision loss such as hemeralopia to blindness.

Diagnosis is usually performed by ophthalmic fundoscopy and DNA testing. As there is no treatment for this condition, breeding dogs are usually testing prior to mating to prevent offspring being affected.

Even in severely affected dogs with progressive blindness, good quality of life is present, providing the owner is aware of the ongoing need for care.
