Progressive Retinal Atrophy, rcd1 in Dogs

Category: Eye
Breeds documented: 1
Published sources: 5

Overview

The light-sensing cells in the retina fail early in this inherited form of progressive retinal atrophy. The retina lies at the back of the eye and helps produce vision. Night vision is affected first, with sight loss progressing to daytime vision as well. Signs can begin in very young puppies, and affected dogs may become completely blind within their first year.

Signs to watch for

Hesitating in dark rooms or outside after sunset.
Bumping into objects in unfamiliar places.
Pupils that look unusually large.

Night blindness can begin around 6 weeks of age.

When to get help Book a vet visit when you notice changes in your dog's vision.

Diagnosis and tests

A DNA test for the rcd1 change in PDE6B can identify genetically affected dogs and carriers. A vet also examines the retina, and an electroretinogram can measure its response to light. This DNA test identifies this particular variant rather than every cause of progressive retinal atrophy.
