Progressive retinal atrophy (PRA) is an inherited disease that occurs in many breeds of dogs and is reflected in various clinically indistinguishable forms. Progressive rod and cone degeneration in retina leads to progressive vision loss, which ends with total blindness. RCD4 is a form of PRA that was first described in Gordon Setters and later found in several other dog breeds. Gradual photoreceptor cell degeneration is typical for this form of the disease. Clinical signs usually become evident later in life (approx. 10 years of age).
