Progressive retinal atrophy (PRA-XL, X-linked progressive retinal atrophy)

Progressive retinal atrophy (PRA) in dogs is a group of genetically heterogeneous inherited retinal disorders characterized by progressive degeneration and cell death of photoreceptors. X-linked progressive retinal atrophy (XL PRA) is an X-linked form of retinitis pigmentosa. Affected dogs have normal retina at birth. The first clinical symptoms appear at 6 months. Rod light receptors begin to appear irregularly damaged, later cone damage arises, and at an age of 4 years affected dogs are usually completely blind. Symptoms include progressive deterioration of central vision, mild photophobia, and moderate to high myopia.
