A congenital defect that causes peripheral vision loss first, progressing to night blindness, and then to total blindness in Papillons. Never breed a dog that is afflicted with this defect.
A progressive degeneration of the retina that is inherited.
A recessively inherited eye disease in which the retina degrades until the dog becomes blind. Very rare in Australian Shepherds. Traumatic retinal damage may be misdiagnosed as PRA.
Retinal degeneration that can lead to blindness
degeneration of the retina; currently we have no confirmed cases of PRA within the Havanese breed
degeneration of the retinal vision cells which progresses to blindness. ( info)
A disease which results in thinning, shrinking retinal cells and central or total blindness. This happens gradually. About PRA, here's where I totally agree with Val regarding getting them to an eye specialist for a baseline which my regular vet did not recomment, but we did it anyway. The eye doctor saw this before Max developed cataracts. Max is not a candidate for cataract surgery as a result of this condition.(from Anne & Max) See also cataracts and dry eye for additional information about eyes.
a progressive degeneration of the retinal tissue.
Progressive retinal atrophy (PRA) is a genetic disease of the retina that occurs bilaterally and is seen in certain breeds of dogs. It causes progressive vision loss culminating in blindness. PRA is actually a group of retinal degenerations with different causes.
