AbstractAnterior ischemic optic neuropathy is a well-recognized clinical syndrome that has been described in patients after an episode of migraine with visual aura (classic migraine) and, less commonly, after an episode of visual aura without headache (acephalgic migraine). Little emphasis, however, has been placed on migraine-associated retrobulbar or posterior ischemic optic neuropathy. We report two cases of visual loss presumed to be due to posterior ischemic optic neuropathy that occurred in the setting of otherwise typical migraine episodes. We review the English language literature on ischemic optic neuropathy associated with migraine. Although most cases of ischemic optic neuropathy associated with migraine are of the anterior variety, posterior ischemic optic neuropathy should be considered in the differential diagnosis of any patient with acute loss of vision and evidence for a retrobulbar optic neuropathy, during or after an attack of migraine headache or following an otherwise typical episode of visual aura without headache (acephalgic migraine).
