What Is Progressive Retinal Atrophy In Dogs?
The retina is the tissue that lines the inner surface of the eye; it forms and transmits images to the brain. In retinal degeneration, the cells of the retina begin lose their function, which leads to impaired vision or blindness.
Progressive retinal atrophy (PRA) is a group of disease that worsens over time, and is seen especially in Collies, Irish Setters, Miniature Poodles, Cocker Spaniels, Briards, Labrador Retrievers, Labradoodles, Mastiffs, Samoyeds and Siberian Huskies. PRA occurs when the cells of a dog’s retinas degenerate. A gene mutation is responsible for the problem. It is, therefore, imperative to know the breeding history before acquiring a puppy, in order to ensure that none of its ancestors has gone blind.
