Retinal dysplasia

Retinal Dysplasia in Dogs
– Most cases of retinal dysplasia in dogs are hereditary.
– It can involve one or both retinas.
– Retinal dysplasia can be focal, multifocal, geographic, or accompanied by retinal detachment.
– 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.

Commonly Affected Dog Breeds
– Bedlington Terrier and Sealyham Terrier: complete retinal dysplasia.
– Rottweiler: focal or multifocal retinal dysplasia.
– English Springer Spaniel and American Cocker Spaniel: focal, multifocal, or geographic retinal dysplasia.

Retinal Dysplasia in Other Animals
– Cats: Retinal dysplasia occurs in utero or in newborns infected with feline leukemia virus or feline panleukopenia, causing necrosis and disorganization of the retina. It appears as folds and rosettes.
– Cattle: Retinal dysplasia occurs in utero through infection with bovine viral diarrhea. It is also inherited in Shorthorns and Herefords, often causing retinal detachment.
– Sheep: Retinal dysplasia occurs by in utero infection with bluetongue disease.
– Horses: Retinal dysplasia is bilateral, not inherited, and appears as multifocal or geographic disease. It is usually accompanied by other eye problems.
– Chickens: No specific information provided.
