BACKGROUND To describe the systemic and visual characteristics and prognosis in patients with nonarteritic ischemicoptic neuropathy (NAION) undergoing different treatments. METHODS Retrospective chart review was performed in Kaohsiung Veterans General Hospital patients from 1995-2005 with a clinical diagnosis of NAION, including nonarteritic anterior ischemic optic neuropathy and posterior is...

A 55-year-old woman was referred to our clinic because of a one-week history of visual loss and raised intraocular pressure in the left eye followed 4 days later by visual loss in the right eye. Slit-lamp examination showed bilateral conjunctival hyperemia, slight diffuse corneal edema, shallow anterior chamber and fixed and dilated pupil in both eyes. Splitting of the anterior layers of the ir...

purpose : to evaluate the correlations between visual field (vf) defects with retinal nerve fiber layer (rnfl) thickness in nonarteritic anterior ischemic optic neuropathy (naion) eyes, compare different gdx parameters with the other healthy contralateral eyes, and calculate receiver operating characteristic (roc) curve for the gdx parameters methods : eighteen patients with unilateral naion fr...

OBJECTIVES To determine whether early recognition and detection of thrombocytosis in patients with giant cell arteritis can help secure an earlier diagnosis, and whether it can help differentiate cases of arteritic optic neuropathy from other forms of optic neuropathy. METHODS Medical and ophthalmologic records from 1993 to 1998 of the authors' patients with biopsy-proven temporal arteritis v...

conclusions demyelinating disease, anterior ischemic optic neuropathy, non-arteritic anterior ischemic optic neuropathy, autoimmune disease, and hereditary optic neuropathy could cause optic neuropathy. normal cbc parameters and the absence of clinical manifestations of vitamin b12 deficiency could not rule out its diagnosis. careful physical examinations and history-taking with a classical app...

BACKGROUND Nonarteritic ischemic optic neuropathy affects the anterior portion of the optic nerve and is characterized by sudden, painless visual loss. The affected eye has a relative afferent pupillary defect. The typical funduscopic appearance includes optic disc edema, with associated nerve fiber layer hemorrhage. Risk factors include advanced age, systemic hypertension, nocturnal hypotensio...
