Optic Disc Structure in Anterior Ischemic Optic Neuropathy

Ophthalmology, 1984
The etiology of anterior ischemic optic neuropathy (AION), when not associated with giant cell arteritis, is usually unknown. Clinical, pathologic, and experimental studies have not determined a cause. The optic disc appearance in both the involved and normal fellow eye was studied in 51 patients with acute nonarteritic AION.

Pain in Anterior Ischemic Optic Neuropathy

Journal of Neuro-Ophthalmology, 1995
The diagnoses of both anterior ischemic optic neuropathy (AION) and optic neuritis are clinical ones with significant overlap of symptoms and signs. This study investigates the presence and character of pain at the onset of AION, in order to evaluate this symptom as a differentiating diagnostic feature between optic neuritis and AION.Forty-one ...

Current Opinion in Ophthalmology, 2002
Nonarteritic anterior ischemic optic neuropathy refers to an idiopathic ischemic process of the anterior portion of the optic nerve. The typical presentation is sudden and painless visual loss with examination features of an optic neuropathy. Among the various associated risk factors are optic disc morphology, advanced age, systemic arterial ...

Nonarteritic Anterior Ischemic Optic Neuropathy

Current Treatment Options in Neurology, 2010
Currently there is no generally accepted, well-proven treatment for nonarteritic anterior ischemic optic neuropathy (NAION). Most proposed treatments are empirical and include antithrombotics, vasodynamic agents, treatments aimed at reducing optic disc edema, and various neuroprotective strategies.

Anterior Ischemic Optic Neuropathy

Ophthalmologica, 2010
3 cases of acute optic neuropathy in juvenile diabetics are reported. The neuropathy included initially optic disc edema (ODE), usually with prominent, dilated and frequently telangiectatic vessels over the disc, and later, generally, development of optic disc-related visual field defects.

Subretinal neovascularization in anterior ischemic optic neuropathy

Graefe's Archive for Clinical and Experimental Ophthalmology, 1991
A 66-year-old man with typical anterior ischemic optic neuropathy in one eye suffered from edema of the optic disc without functional changes in the fellow eye. However, 7 months later, a reduction in visual acuity, a change in the visual field and a worsening of the contrast-sensitivity curve demonstrated the development of typical anterior ischemic ...

Anterior Ischemic Optic Neuropathy

Archives of Ophthalmology, 1976
Although glaucoma, especially the low-tension variety, is discussed in passing, this book is mainly about the entity I have usually called "ischemic papillitis," which is also known by several other names. The author points out that his designation, "anterior ischemic optic neuropathy" (AION), seems the most accurate name for this condition.

Anterior Ischemic Optic Neuropathy in Graves?? Disease

Journal of Neuro-Ophthalmology, 1994
Optic neuropathy occurred in two patients suffering from Graves' disease with marked limitation of eye movement. Optic nerve changes were moderate. They consisted of parapapillary flame-shaped hemorrhages, swelling of the disc, and bundle defects in the visual field on the involved side.
