This study aims to assess 1000 mg citicoline each day given for 60 days on chronic phase NAION (non–arteritic anterior ischemic optic neuropathy) patients. Double masked randomized clinical trial divided the patients into 2 groups: group (C–NAION) and placebo (P–NAION). Analysis was done in 17 group. There were increament of ? amplitude P50 30 C–NAION (0,775±2,6 µV) N95 (–0,356±2,992 but statis...

AIM/PURPOSE To present a summary of 10 cases of non-arteritic anterior ischemic optic neuropathy (NAION) in patients who received phosphodiesterase type 5 (PDE-5) inhibitors. METHODS A case series of 10 patients who, after regular intake of Sildenafil, presented with a first episode of NAION in one eye. NAION was diagnosed based on the following criteria: acute, painless, unilateral loss of v...

PURPOSE To compare the patterns of retinal ganglion cell damage between primary open-angle glaucoma (POAG) and non-arteritic anterior ischaemic optic neuropathy (NAION). METHODS In total, 35 eyes with unilateral NAION, and 70 age- and average peripapillary retinal nerve fibre layer (RNFL) thickness-matched eyes with POAG, were enrolled as disease groups; 35 unaffected fellow eyes of the NAION...

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...

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...

OBJECTIVES To determine the differences in pupillary light reflex (PLR) between the acute and chronic phases of optic neuritis (ON) and nonarteritic anterior ischemic optic neuropathy (NAION). METHODS The study included 30 patients with ON and 22 patients with NAION whose PLR were measured by a dynamic pupillometer (PLR-200; NeurOptics Inc., Irvine, USA). Age-matched controls included 58 heal...

PURPOSE Recent literature suggests a genetic component for non-arteritic anterior ischemic optic neuropathy (NAION). We examined the association of the insertion/deletion (I/D) polymorphism of the angiotensin-converting enzyme gene, of the M235T polymorphism of the angiotensinogen gene, and of the A1166C polymorphism of the angiotensin II type 1 receptor gene with NAION. METHODS Forty-seven p...

PURPOSE Both non-arteritic anterior ischemic optic neuropathy (NAION) and primary open-angle glaucoma (POAG) damage retinal ganglion cell axons, which are perfused by the radial peripapillary capillaries. To evaluate the pattern of ischemia, we compared peripapillary capillary density (PCD) in NAION eyes to POAG eyes matched for visual field mean deviation and retinal nerve fiber layer thicknes...

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 ...

Nonarteritic anterior ischemic optic neuropathy (NAION) is the most prevalent optic nerve disorder among patients over 50 years of age, characterized by sudden onset, painless visual loss, with an accompanying relative afferent pupillary defect and optic disc edema. Although the pathophysiology of NAION has not been fully elucidated, several risk factors have been considered, including advanced...
