Introduction: The incidence of fellow eye involvement in non-arteritic anterior ischemic optic neuropathy (NAION) is 15% at 5 years after initial onset, although risk factors have not been identified. aim this article to determine the factor that could influence with NAION. Case Report: A 72 year-old male presented gradual painless vision loss left (LE) for 3 months. He did smoking habit. BCVA ...

PURPOSE To determine whether an association exists between sleep apnea and open-angle glaucoma, normal-tension glaucoma, nonarteritic ischemic optic neuropathy (NAION), papilledema, or idiopathic intracranial hypertension (IIH) and whether treatment with continuous positive airway pressure affects the development of these conditions. DESIGN Retrospective, longitudinal cohort study. METHODS ...

The intrinsically photosensitive retinal ganglion cells (ipRGCs) express the photopigment melanopsin, which is sensitive to blue light. Previous chromatic pupillometry studies have shown that the post-illumination response is considered an indicator of the melanopsin activation. The aim of this study was to investigate the ipRGC mediated pupil response in patients with a unilateral non-arteriti...

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 safety...

OBJECTIVE To better define the concordance of visual loss in patients with nonarteritic anterior ischemic optic neuropathy (NAION). METHODS The medical records of 86 patients with bilateral sequential NAION were reviewed retrospectively, and visual function was assessed using visual acuity, Goldmann visual fields, color vision, and relative afferent papillary defect. A quantitative total visu...

Objective. To determine whether acupuncture treatment impacts the clinical efficacy of degenerative damage of the optic nerve caused by nonarteritic anterior ischemic optic neuropathy (NAION). Methods. 69 patients (93 eyes) with NAION who had been treated by acupuncture which is performed on different acupoints related to eyes by vertical insertion or Fingernail-pressure needle insertion. The b...

Abstract Introduction Non-arteritic ischemic optic neuropathy (NAION) is the most common nerve disorder among patients over age of 50. Several risk factors have been associated with NAION including systemic hypertension, diabetes mellitus, advanced age, and certain disc morphologies. A significant association between obstructive sleep apnea (OSA) has also reported. Here, we present a case middl...

Herein, we report a case of nonarteritic anterior ischemic optic neuropathy (NAION) following uneventful pars plana vitrectomy for macular hole treatment. A 56-year-old previously healthy woman presented with a full-thickness macular hole in right eye (OD) and small cup-to-disc ratios in both eyes. Five days after surgery, she noticed sudden painless loss of vision in OD and was found to have a...

BACKGROUND To evaluate the ocular pulse amplitude (OPA) in patients with chronic non-arteritic anterior ischaemic optic neuropathy (NAION). METHODS This cross-sectional study comprised a study group of 30 eyes from 30 patients with NAION and a control group of 31 eyes from 31 age and gender-matched healthy subjects. Bilateral OPA was measured with dynamic contour tonometry (DCT) and was compa...
