What is CEA? CEA stands for Collie Eye Anomaly, a disease that is commonly seen in collies. However, collies are not the only breed to suffer from this disease. CEA is actually a group of eye conditions, ranging from mild to severe. Fortunately, it is easily detected with an eye examination by a Canine Ophthalmologist. The test should be done by the breeder, when the puppies are 5 - 6 weeks old. Reputable, ethical breeders will have their puppies tested before they are sold to new families. The good news is that most CEA does not impair the dog’s vision, so owners will rarely see any discernable difference between collies with CEA and those who are normal eyed.
The Collie Club of America's Code of Ethics requires that all dogs that are sold or placed, be in good condition, free of communicable diseases with their health guaranteed for a reasonable length of time. This should include a written health record, inoculation schedule and the results of the eye exam. If a breeder refuses to provide you with the puppy's health record or results of the eye exam, then you may want to find another breeder.
PRA, Progressive Retinal Atrophy, is another eye condition. It is unrelated to CEA, and it is a degenerative disease that can result in blindness. Most dogs with PRA will be blind by the time they are a year old. You can learn more about PRA, by visiting this site:
