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...

BACKGROUND Ischemic optic neuropathy is the most common cause of perioperative vision loss. The authors sought to determine its incidence and identify risk factors that may contribute to perioperative ischemic optic neuropathy associated with nonophthalmologic surgical procedures at their institution. METHODS Seventeen patients who experienced perioperative ischemic optic neuropathy were incl...

Visual loss is a traumatic occurrence that has been reported after prone spine surgical procedures performed under general anesthesia. The most common cause of postoperative visual loss is ischemic optic neuropathy. Although the incidence of postoperative visual loss is rare, this devastating injury has been reported more frequently. Several factors increase the risk for the development of isch...

CASE REPORT We report the case of a young patient with unilateral anterior ischemic optic neuropathy, with no known cardiovascular risk factors and visual acuity preserved with positive anticardiolipin antibodies as a unique find. DISCUSSION Non-arteritic anterior ischemic optic neuropathy in the context of antiphospholipid syndrome is an uncommon finding, but it must be considered in the dia...

Purpose To report a case of bilateral central retinal artery occlusion with both anterior and posterior ischemic optic neuropathy. Observations A 65-year-old Caucasian woman presented with acute respiratory distress syndrome and septic shock. After treatment with vasopressors and prolonged prone positioning, she was noted to be bilaterally completely blind on hospitalization day 12. Evaluatio...

BACKGROUND The incidence of anterior ischemic optic neuropathy after coronary artery bypass graft procedures ranges from 1.3 to 0.25%. The mechanisms of anterior ischemic optic neuropathy after cardiovascular procedures remain undefined but many systemic and related-to-surgery risk factors could underlie anterior ischemic optic neuropathy. In this case, we report a rare presentation of a bilate...

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 ...

purpose : evaluation of efficacy of memantine (n-methyl-d-aspartate receptor antagonist) on visual function of patients with acute non-arteritic ischemic optic neuropathy (naion). methods : the study was conducted as interventional case series from november 2005 through november 2006 in farabi eye hospital . twenty-two patients with acute naion of less than 8 weeks duration entered the study. m...

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...
