Retinal dysplasia is an eye disease affecting the retina of animals and, less commonly, humans.
It is usually a nonprogressive disease and can be caused by viral infections, drugs, vitamin A deficiency, or genetic defects.
Focal and multifocal retinal dysplasia appears as streaks and dots in the central retina.
Geographic retinal dysplasia appears as an irregular or horseshoe-shaped area of mixed hyper or hyporeflectivity in the central retina.
Cataracts or glaucoma can also occur secondary to retinal dysplasia.
