In collaboration with

Autosomal recessive progressive retinal atrophy is a group of genetic, degenerative eye disorders. These conditions most often lead to blindness. They get their name because these genetic conditions are passed down in the autosomal recessive fashion, meaning both parents must be carriers of a progressive retinal atrophy mutation for a litter to inherit it.

What does this mean for a dog with this trait?

There is no cure for autosomal recessive progressive retinal atrophy. In earlier stages, increased lighting may help. As the condition progresses, dogs will need additional supervision to help them navigate their surroundings. It may also be helpful to block off hazardous areas, like stairs and exits.

Symptoms

Symptoms of autosomal recessive progressive retinal atrophy typically begin as signs of night blindness. Dogs may be increasingly hesitant or clumsy in low-light conditions. As the condition progresses, dogs will lose daytime vision as well. Ultimately, dogs with the condition will become totally blind.
