General information
Progressive Retinal Atrophy (pd-PRA), also known as Leber Congenital Amaurosis (LCA), or Retinal Pigment Epithelial Dystrophy, is an eye disorder that results in the degeneration of the retina, causing degraded vision and ultimately blindness. This variant of the disease is caused by a recessive mutation to the gene AIPL and is observed in the Persian cat.
Clinical features
Affected cats begin showing signs of vision loss, starting with reduced pupillary reflexes, as early as two or three weeks of age. The disease is progressive, and by the age of approximately 17 weeks, affected cats are likely to be almost totally blind.
