Ischemic Neuropathy

Ischemic optic neuropathy is infarction of the optic disk. The only constant symptom is painless vision loss. Diagnosis is clinical. Treatment is ineffective.Two varieties of optic nerve infarction exist: nonarteritic and arteritic. The nonarteritic variant occurs more frequently, typically affecting people about 50 yr and older. Vision loss tends not to be as severe as in the arteritic variant, which usually affects an older group, typically about 70 yr and older. Most ischemic optic neuropathy is unilateral. Bilateral, sequential cases occur in about 20%, but bilateral simultaneous involvement is uncommon. Bilateral involvement is much more common among arteritic than nonarteritic cases. Atherosclerotic narrowing of the posterior ciliary arteries may predispose to nonarteritic optic nerve infarction, particularly after a hypotensive episode. Any of the inflammatory arteritides, especially giant cell arteritis (see Giant Cell Arteritis), can precipitate the arteritic form.

Ischemic optic neuropathy is a sudden loss of central vision, side vision or both due to a decreased or interrupted blood flow to the eye’s optic nerve. Anterior ischemic optic neuropathy is the most common cause of acute optic neuropathy in older age groups. It can be nonarteritic ischemic optic neuropathy or arteritic, the latter being associated with giant cell arteritis. Patients with both anterior and posterior ischemic optic neuropathy present with acute vision loss in one or both eyes that is not associated with pain.
