Ischemic Optic Neuropathy
Prognosis for Ischemic Optic Neuropathy
There is no effective treatment for nonarteritic ischemic optic neuropathy. However, about one third of people with nonarteritic ischemic optic neuropathy have partial improvement of their vision spontaneously. In this condition, repeat episodes in the same eye are rare, but the other eye is affected in 15 to 20% of people. In the arteritic variety caused by Giant Cell Arteritis , vision loss is typically greater than in nonarteritic ischemic optic neuropathy. Prompt treatment with corticosteroids does not restore lost vision in the affected eye but protects the unaffected eye. Inadequate treatment increases the risk of vision loss in the other eye.
