Postoperative Ischemic Optic Neuropathy
Spine, 2010Systematic literature review.To determine if there are predictors or preventative measures for postoperative ischemic optic neuropathy (ION) associated with spine surgery.Postoperative ION is a devastating complication that is most common after cardiac and spinal fusion surgery.

Background: Nonarteritic anterior ischemic optic neuropathy (NAION) in young patients (age ≤50) accounts for a minority of all cases of NAION and is more highly associated with crowding of the optic nerves and bilateral involvement than NAION in older ...

Semaglutide and Nonarteritic Anterior Ischemic Optic Neuropathy Risk Among Patients With Diabetes.
JAMA ophthalmologyImportance Recent studies have suggested an association between nonarteritic anterior ischemic optic neuropathy (NAION) with semaglutide usage. However, the limitations of those analyses warrant further investigation, given the frequency of use of these ...

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 ...

BACKGROUND Nonarteritic anterior ischemic optic neuropathy (NA-AION) associated with optic disc drusen (ODD) is termed ODD-AION, where NA-AION with no evidence of ODD is simply termed NA-AION.

Neurologic Clinics, 1991
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 ...

Continuum, 2019
Vision is often threatened or lost by acute ischemic damage to the optic nerves. Such pathology most often affects the anterior portion of the nerve and is visible on funduscopic examination. Ischemic optic neuropathy is associated with typical vascular risk factors and with one systemic disease in particular: giant cell arteritis (GCA).

Migrainous ischemic optic neuropathy
Neurology, 1985Anterior ischemic optic neuropathy (AION) is a stroke syndrome of the eye seen in isolation or as a manifestation of underlying disease. A case of migrainous AION is reported, and the implications of anterior visual pathway migraine discussed.

Anterior Ischemic Optic Neuropathy
Archives of Neurology, 1981Though anterior ischemic optic neuropathy (AION) has been widely reported, it is not fully appreciated as one of the commonest causes of impaired vision in persons past middle age. These patients are not infrequently suspected of having an intracranial tumor.
