Summary
Posterior ischemic optic neuropathy can cause vision loss after migraine. This condition, often overlooked, should be considered in patients experiencing sudden vision loss during or after a migraine episode.
Area of Science:
- Ophthalmology
- Neurology
Background:
- Anterior ischemic optic neuropathy is recognized after migraine with visual aura.
- Migraine-associated posterior ischemic optic neuropathy is less emphasized.
Purpose of the Study:
- To report cases of posterior ischemic optic neuropathy linked to migraine.
- To review literature on ischemic optic neuropathy and migraine.
Main Methods:
- Case report of two patients with visual loss.
- Literature review of ischemic optic neuropathy associated with migraine.
Main Results:
- Two cases of presumed posterior ischemic optic neuropathy occurred during migraine episodes.
- Most literature focuses on anterior ischemic optic neuropathy, not posterior.
Conclusions:
- Posterior ischemic optic neuropathy should be considered in migraine patients with acute vision loss.
- Consider this diagnosis in visual aura without headache (acephalgic migraine) cases.
