title: Bilateral neuroepithelial choristomas of the optic disc in a cynomolgus monkey (Macaca fascicularis): a case report.
abstract: A 6-year-old intact male cynomolgus monkey of Chinese origin was received at the Sierra Biomedical Facility. While physical examination revealed good body condition with no abnormalities, routine ophthalmic examination revealed bilateral proliferative optic neuropathy involving the dorsal aspect of the optic disc. No changes were noted in the appearance of the lesions over 8 months, and fluoroescein angiography revealed no abnormalities other than obstruction of the view of the retinal vessels by the lesions. Histopathologic studies revealed characteristics consistent with a diagnosis of bilateral neuroepithelial choristoma.
