A case of temporal arteritis with anterior ischemic optic neuropathy

A 49 year old female developed headache and fever manifestations of temporal arteritis. Four days later, horizontal inferior hemianopia led to the diagnosis of anterior ischemic optic neuropathy in her right eye. Systemic prednisolone treatment prevented further progression of optic neuropathy. The left eye has remained intact. Review of ten similar cases in Japan has shown that early treatment with systemic corticosteroid prevented involvement of the fellow eye.
