Collie eye anomaly (CEA, Choroidal Hypoplasia-CH) is one of hereditary diseases of dog's eyes, characterized by different levels of impairment of the retina and choroid sclera that occurs during development of the eye. The inheritable disease is not progressive and the state after eye development remains stable. For this disease no drugs exist and it cannot be treated. It is important that you choose the best DNA test for dogs, to discover this hereditary disease early on. The main symptom in affected dogs is hypoplasia (under development) of choroid, which is an important layer of the eye under the retina. In dogs with more extensive CEA disease the hypoplasia of retina or coloboma development may occur. The extent of this disease is different in each dog. Known symptoms range from mild to very severe that can lead to blindness.
