Clinical studies on progressive retinal atrophy in 31 dogs
During a 2-year period, 31 cases of a hereditary retinal degeneration in dogs bred in India were found mainly suspected for progressive retinal atrophy (PRA) with typical history of initial nyctalopia followed by hemeralopia. Out of 31 PRA suspected dogs, 8 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 (...

متن کاملProgressive retinal atrophy in Tibetan terriers.
Progressive retinal atrophy was studied in 17 Tibetan Terriers. The diagnosis was made on the basis of clinical signs of the disease, retinal histopathologic findings, or both. Affected dogs were the progeny of matings of affected or ophthalmoscopically normal dogs. Results of the mating supported a simple autosomal recessive mode of inheritance. The disease initially could be diagnosed by find...
متن کاملProgressive Retinal Atrophy in the Border Collie: A new XLPRA
BACKGROUND Several forms of progressive retinal atrophy (PRA) segregate in more than 100 breeds of dog with each PRA segregating in one or a few breeds. This breed specificity may be accounted for by founder effects and genetic drift, which have reduced the genetic heterogeneity of each breed, thereby facilitating the identification of causal mutations. We report here a new form of PRA segregat...
متن کاملEarly-onset, autosomal recessive, progressive retinal atrophy in Persian cats.
PURPOSE An early-onset retinal degenerative disease has been identified in Persian cats. This study genetically, clinically, and histologically characterized the disease. A breeding colony was established to assist with identification of the causative gene and to provide a resource for vision research. METHODS Cats were produced from testcross breedings. Kittens underwent serial ophthalmic an...
