title: Postirradiation optic neuropathy in antral carcinoma.
abstract: A case is described of a patient who developed radiation-induced optic neuropathy 18 months following cobalt-60 irradiation for carcinoma of the left maxillary antrum and ethmoid sinus. This case is unusual because of the early onset of the optic nerve damage following radiation therapy and the ultimate emergence of the eye involved by tumor compression as the better eye in terms of visual acuity.
