Congenital eye malformations occur in multiple breeds and can have different genetic backgrounds. In the Golden retriever a highly variable eye disease caused by a single genetic mutation is described. This trait has incomplete penetrance this means that carriers and affected animals are likely, but not guaranteed, to present eye anomalies. The malformations of one or both eyes can range from visual impairment, wandering eyes (nystagmus), cataract, retinal detachment to deformations of the lens, cornea and/or retina.

This mutation can be tested by our Congenital Eye Malformation test (test number H727) and is also added to the CombiBreed  Golden Retriever package (test number H322).
