Definition

Ischemic optic neuropathy is the most common acute optic neuropathy in adults over the age of 50 years, accounting for many cases of blindness or seriously impaired vision in that age group; however, no age is immune as this disorder has been reported in younger patients as well, including children.

Etiology

A typical classification divides anterior ischemic optic neuropathy into an arteritic (AAION) and non-arteritic (NAION) variants, which has important clinical and prognostic implications. AAION is associated with temporal (giant cell) arteritis and NAION is often related to atherosclerosis.

Clinical Presentation

The typical presentation of both AAION and NAION is painless loss of vision typically associated with optic disk swelling accompanied by flame-shaped (splinter) hemorrhages. However, vision is usually much worse in AAION compared to NAION (light perception vs. 20/200 vision). The visual loss is commonly described as sudden but progression over several days is...
