Online published on 26 July, 2017. Abstract During two years study, 31 cases of progressive retinal atrophy (PRA) were recorded in dogs with typical history of initial nyctalopia followed by hemeralopia. Out of 31 PRA suspected dogs, eight dogs (26%) were from the age group of 1-5 years, 15 (48%) 6-10 years and the rest (26%) 11-15 years. The most predominant breed was Spitz (18 dogs-58%). Detailed ophthalmologic was conducted in all the dogs. Ophthalmoscopic and fundoscopic changes included hyper reflectivity and discoloration of the tapetal area, marked attenuation of retinal vessels, depigmentation in non-tapetal area and optic disc atrophy with scalloped borders. Funduscopy revealed typical signs of PRA with change in tapetal reflectivity. The signs were almost symmetrical for both eyes and severity of abnormalities was somewhat variable among the affected dogs.
