CASE REPORT We report the case of a 62-year-old man with classic nonarteritic anterior ischemic optic neuropathy (NAION) in the left eye and incipient NAION in the right eye. Incipient NAION progressed to classic NAION after 3 weeks. There was no ocular, orbital, neurologic, or systemic disorder that was responsible for optic disc edema. DISCUSSION Recently, Hayreh has described the new entit...

Purpose We hypothesized that the edema/swelling in the retina due to acute nonarteritic anterior ischemic optic neuropathy (NAION) can induce retinal folds (RF). We determined the pattern and frequency of folds in NAION at presentation and in follow-up, and the relationship between folds and a number of functional and structural parameters over time. Methods We prospectively studied eyes with...

Visual acuity and quantitative perimetry (Octopus Program 32) testing was performed in the acute (< 30 days after onset) and convalescent (> 3 months after onset) phases of disease in 27 patients with untreated NAION. Initial group mean acuity and sensitivity loss were compared to final values using the t test. Proportions of patients demonstrating a change of > 2 lines acuity or > 2 dB mean se...

This study is to investigate the clinical characteristics of patients with nonarteritic anterior ischemic optic neuropathy (NAION). Totally 133 patients (156 eyes) were included in this study. At the first visit and follow-up visits, the patients were subjected to the ophthalmic evaluations, including the fundus photography, visual field (VF) test, fluorescein fundus angiography, and optical co...

PURPOSE The risk of visual loss after nonocular surgeries is very low, between 0.2% and 4.5%. According to the American Society of Anesthesiologists, ischemic optic neuropathy has been reported mostly after spinal surgery (54.2%), followed by cardiac surgery and radical neck dissection (13.3%). It may occur in association with some conditions that include systemic hypotension, acute blood loss ...

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...
