Collie eye anomaly is which of the following?

• A. Inherited corneal dystrophy
• B. Hereditary eye disease in collies and other herding breeds
• C. Glaucoma in puppies
• D. Cataract in old dogs

Answer: (B)

Collie eye anomaly is a hereditary developmental defect of the eye’s posterior segment, most commonly seen in collies and other herding breeds. It involves abnormalities of structures like the choroid and sclera and can range from mild choroidal hypoplasia to severe retinal detachment, which can cause vision loss or blindness in some dogs. Because it’s breed-associated and inherited, it’s a classic example of a congenital hereditary eye disease in these breeds. It’s not a corneal problem like corneal dystrophy, not glaucoma in puppies, and not cataracts in aging dogs, since those conditions affect different parts of the eye or arise later in life. Understanding that CEA can be present from birth and vary in severity helps explain why breed screening and thoughtful breeding decisions are important.
