RETINAL DYSPLASIA IN DOGS

Most cases of retinal dysplasia in Dog s 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. Retinal detachment occurs with complete retinal dysplasia, and is accompanied by blindness in that eye. Cataract s or Glaucoma can also occur secondary to retinal dysplasia. Other causes of retinal dysplasia in dogs include infection with Canine Adenovirus or Canine Herpesvirus , or Radiation of the eye in newborns.
