Retinal dysplasia in the crab-eating fox (Cerdocyon thous)
Previously described in humans and domestic animals, retinal dysplasia has three clinical forms: focal/multifocal, geographic and total. A young orphan crab-eating fox (Cerdocyon thous) from wildlife, male, approximately 45 days old referred to the Wildlife Medicine and Ophthalmology Services of the “Governador Laudo Natel” Veterinary Hospital of the Universidade Estadual Paulista, Jaboticabal Campus, SP, Brazil, where it received primary outpatient care. The patient was in good general health condition, without hematological, biochemistry or serological alterations and no signs of visual impairment. Indirect binocular ophthalmoscopy showed retinal changes in the left eye, distributed over the tapetal area in the form of grayish folds and rosettes. In the affected areas, tapetal reflectivity was reduced. No other ophthalmic abnormalities were observed. This is the first report of retinal dysplasia in the crab-eating fox (Cerdocyon thous) from wildlife.
