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).

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 ...

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 ...

Anterior Ischemic Optic Neuropathy
Seminars in Ophthalmology, 1995AION is the most common acute optic neuropathy in patients over 50 and, although the diagnosis is often straightforward, our methods for managing the associated visual loss are inadequate. Analysis of the wealth of information gained from recent clinical studies may move us closer to an effective therapy.

Not everything is ischemic optic neuropathy
Survey of OphthalmologyA 71-year-old woman developed sudden, painful, decreased vision in the left eye accompanied by progressive instability. Initial examination revealed left optic disc edema, and macular optical coherence tomography confirmed the presence of intraretinal and subretinal fluid, as well as hyperreflective material under the retinal pigment epithelium ...

Histopathology of Ischemic Optic Neuropathy
American Journal of Ophthalmology, 1970A 67-year-old woman, a retired writer, was ad mitted to the hospital on March IS, 1968. She stated that she had been in excellent health until the previous summer, when she noted an unusual lack of energy. In December, 1967, she experienced the abrupt onset of bitemporal aching pains which waxed and waned in severity and which radiated to her jaw ...

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.

Surgery for Ischemic Optic Neuropathy
Archives of Ophthalmology, 1995ANTERIOR ISCHEMIC optic neuropathy, like mitral valve prolapse or galactorrheaamenorrhea from pituitary microadenomas, is one of those disorders that must have always been with us but that was hardly known as recently as 35 years ago. We now recognize that anterior ischemic optic neuropathy may have a higher incidence than any other optic neuropathy ...

Ischemia of the optic nerve may occur in several forms, usually associated with vasculopathic risk factors or vasculitis, and may present with various patterns of optic disc appearance and dysfunction. Though a proven therapy is not available for the most common syndromes, correct identification may present severe visual loss or systemic complications ...

Acute Ischemic Optic Neuropathy
JAMA: The Journal of the American Medical Association, 1985Acute anterior ischemic optic neuropathy (AION) is a common cause of profound visual loss in the elderly and the not-so-elderly and is often associated with systemic disorders. Even so, this condition is not frequently discussed in the medical literature outside ophthalmology specialty journals.
