Some Golden’s carry genes for Central Progressive Retinal Atrophy (CPRA) which is a progressive deterioration of the light-receptive area (retina) of the eye, and may result in complete blindness at a young age. Hereditary cataracts are also common eye problems in the Golden Retriever. Examination by a Board-certified veterinary ophthalmologist is necessary to determine if the cataract is of concern from a genetic standpoint. If there are any questions, the dog should not be bred. Golden Retrievers used for breeding stock should be examined annually until at least eight years of age or longer, as hereditary eye problems can develop at varying ages. Dogs that have undergone examination by a Board-certified veterinary ophthalmologist and found to be free of hereditary eye disease can be registered with the Canine Eye Registration Foundation (CERF). _Note that not all forms of cataracts disqualify a dog from getting a CERF number; you should ask to see a copy of the paperwork the vet filled out (the original is sent to CERF). The breeder should be able to show you the paperwork on both parents for eye examinations. It’s important to verify that the dogs are being examined annually and not just once. If the breeder has older dogs, ask if they are still being examined as well.
