[Ophthalmic manifestations of giant cell arteritis--two cases report].

Two elderly women had catastrophic visual loss due to giant cell arteritis. The other eyes of both were attacked within two weeks. Bilateral central retinal artery occlusion, negative temporal artery biopsy and relentless nature course were noted despite treatment with a high dose of corticosteroid in one case. Unilateral central retinal artery and ischemic optic neuropathy were noted in the other case with typical pictures in temporal artery biopsy.
