Central Progressive Retinal Atrophy




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.


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.


Information needed.


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


There is currently no treatment for this condition.


There is no known prevention for this condition.


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