Progressive Retinal Atrophy (Bas-PRA) – Basenji

Initial symptoms are visual loss in dim light (night blindness), which gradually progresses to total blindness. Unless the dog is used for high visual performance tasks such as agility work, the reduction in the visual field (tunnel vision) may not be noticed. Despite tunnel vision and night blindness, many affected Basenjis retain adequate forward daylight vision for many years, sometimes for their entire natural life.
