Ischemic Optic Neuropathy
Prognosis for Ischemic Optic Neuropathy
There is no effective treatment for the nonarteritic variety of optic nerve infarction; however, up to 40% of patients spontaneously recover some useful vision. In the arteritic variety caused by giant cell arteritis, losses of visual acuity and visual field are typically greater. Prompt treatment does not restore lost vision in the affected eye but protects the unaffected eye. Inadequate treatment risks relapses and additional vision loss.
