Ischemic optic neuropathies (IONs) are the most frequent acute optic neuropathy in patients older than 50 years. They are classified according to the location of the ischemic damage into anterior ION and posterior ION. Ischemic optic neuropathies may also be categorized based on the presence or absence of temporal arteritis as an underlying etiology ...

Anterior ischemic optic neuropathy (AION) is the most common cause of acute optic neuropathy after age 50, but may also occur in younger patients. The diagnosis is clinical and includes painless visual loss associated with a relative afferent pupillary defect and disc edema.

Embolic Ischemic Optic Neuropathy
American Journal of Ophthalmology, 1978On examining the postmortem enucleated eyes of a 68-year-old man, we found the left eye had focal infarction 3 mm behind the lamina cribrosa caused by thromboembolic compromise of three discrete pial and pial-derived arterioles. The optic nerve had been destroyed focally, whereas the retinal and choroidal tissue supplied by a similarly occluded vessel ...

ION typically affects the older population with a sudden decrease in vision, altitudinal visual field loss, and a swollen optic nervehead. Systemic hypertension and diabetes mellitus are the most commonly associated medical problems. Occlusion of the posterior ciliary arterial blood supply to the retrolaminar optic nerve leads to axoplasmic stasis and ...
