Condition Overview

Central progressive retinal atrophy (CPRA) is a degenerative retinal disease that affects both eyes. It is less common than PRA and occurs in older dogs. CPRA affects the pigment cells at the center of the retina.

Symptoms

Since the central part of the retina (where the dogs vision is usually best) is the primary target of the disease, a dog with CPRA is unable to see stationary objects well, especially in bright light. However, the dog is still able to see moving objects because the motion is perceived at the periphery of the retina. Although vision decreases as the disease progresses, complete blindness is rare.

Causes

Information needed.

Diagnosis

This can be diagnosed on the CERF (Canine Eye Registry Foundation) exam and also through genetic testing.

Treatment

There is currently no treatment for this condition.

Prevention

There is no known prevention for this condition.

Support

Please contact your veterinarian if you suspect your pet may have this condition.
