purpose : to evaluate the therapeutic effect of posterior sub-tenon methyl prednisolone in anterior ischemic optic neuropathy, no class 1 study has shown any conclusive medical or surgical treatment for non-arteritic anterior ischemic optic neuropathy (naion). efficacy of systemic or intravitreal steroids was suggested by some studies. this study was performed to evaluate the efficacy and safet...

introduction hypoparathyroidism might cause various musculoskeletal findings, resembling spondyloarthropathies. case presentation we described a 52-year-old woman, diagnosed as a case of undifferentiated spondyloarthropathy for ten years, who was unresponsive to classic anti-inflammatory therapies. she developed anterior ischemic optic neuropathy and had elevated muscle enzymes during the cours...

purpose: to evaluate the effect of levodopa-carbidopa on improvement of visual acuity, color vision, and visual field in patients with nonarteritic anterior ischemic optic neuropathy (naion) with onset less than 6 wks. methods: in this double-blind randomized controlled trial, 13 patients were treated with levodopa-carbidopa and 12 patients were treated with placebo for 3 weeks. after 6 months,...

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...

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 AND PURPOSE The relation between anterior ischemic optic neuropathy and carotid artery atherosclerotic disease is unclear. We studied patients with anterior ischemic optic neuropathy to determine if they had an increased occurrence of carotid artery stenosis. METHODS Fifteen consecutive patients with anterior ischemic optic neuropathy were evaluated prospectively for cervical carot...

purpose : to evaluate the effects of memantine on improving visual function in patients with acute nonarteritic anterior ischemic optic neuropathy (naion) methods : this was a prospective, double masked, randomized, clinical trial. the study involved 47 subjects with unilateral naion of less than 8 weeks duration. eligible patients were randomly allocated to take either memantine tablets (5 mg ...

background: sleep apnea is temporary cessation or absence of breathing during sleep. significant increase in blood pressure is clinically seen in apneic episodes. the aim of this study was to examine sleep apnea syndrome as a risk factor for non- arthritic anterior ischemic optic neuropathy (naion) in a case control study. methods: nineteen naion patients (9 men and 10 women) and 31 age and sex...
