Coats-like retinopathy in a Young Indian Rhesus Macaque (Macaca mulatta).

A 1-year-old male Indian rhesus macaque presented with a bilateral blindness. Ocular examination, gross and histopathological evaluation, and immunohistochemistry were performed. The major findings were retinal telangiectasia, accumulation of exudate in the intraretinal and subretinal space, and retinal detachment. Coat-like retinopathy was diagnosed, and it has not been previously reported in veterinary medicine.
