We present an interesting case with nonarteritic anterior ischemic optic neuropathy (NAION) accompanied by Buerger's disease. A 43-year-old man was referred to our neuro-ophthalmology clinic with a complaint of visual deterioration in the left eye that started 5 days ago. He suffered from Buerger's disease, and he had acute pain in the right lower limb below the knee. His best corrected visual acuity was 10/10 in the right eye and 2/10 in the left eye by Snellen chart. There was a relative afferent pupil defect in the left eye...

Purpose: Ischemic ocular disorders may be treated by hypervolemic hemodilution. The presumed therapeutic benefit is based on a volume effect and improved rheological factors. The aim was to investigate the acute effect of intravenous hydroxyethyl starch on retrobulbar hemodynamics in patients with nonarteritic anterior ischemic optic neuropathy (NAION). Methods: 24 patients with acute NAION were included. Retrobulbar hemodynamics were measured using color Doppler imaging before and 15 min after intravenous infusion of 250 cc 10% hydroxyethyl starch (HES)...

INTRODUCTION: The management of nonarteritic anterior ischemic optic neuropathy centers around prevention of second eye involvement, without a uniformly accepted therapy for the involved eye. Several researchers have assessed the benefit of steroids with conflicting results. This experimental study was designed to evaluate the efficacy of a single intravitreal triamcinolone acetonide injection (IVTA) in preserving retinal ganglion cells (RGCs) in a rodent model of anterior ischemic optic neuropathy (rAION)...

Purpose: To report a case of a temporal artery biopsy negative anterior ischemic optic neuropathy associated with a recently completed course of pegylated interferon 2 α with ribavirin for chronic hepatitis C. Observations: Despite the early presentation with symptoms and prompt treatment with systemic intravenous steroids the patient experienced deterioration of their optic neuropathy over the following few days. Although nonarteritic anterior ischemic optic neuropathy is a common disorder with known risk factors, the timing of onset of symptoms in our patient was suggestive of a possible etiology related to treatment with ribavirin and interferon 2 α, as found in the previously reported cases...

The aim of this study was to assess damage to retinal ganglion cells (RGC) and morphology of the optic nerve head (ONH) in patients with primary open angle glaucoma (POAG) and non-arteritic anterior ischemic optic neuropathy (NAION). The study included three groups of patients, as follows: 40 eyes with POAG, 40 eyes with NAION and 40 eyes with refraction anomaly. All patients underwent standard automated perimetry and analysis of ONH topography by using confocal scanning laser ophthalmoscopy (CSLO)-HRT II. Visual field defects such as decreased retinal sensitivity prevailed in the eyes with POAG, whereas in the eyes with NAION they were mostly manifested as concentrically narrowed visual field and quadrant excesses...

BACKGROUND: Proliferative diabetic retinopathy leading to vitreous hemorrhage, tractional retinal detachment, and neovascular glaucoma is a major cause of severe sight impairment in adults of working age worldwide. Neovascular glaucoma occurs in 2.5% of patients with proliferative diabetic retinopathy, which is difficult to treat and often leads to blindness. Onset of neovascular glaucoma with rapid progression to blindness within a few weeks of a successful coronary artery bypass graft procedure is not known with this clinical entity...

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 bilateral anterior ischemic optic neuropathy after coronary artery bypass graft and speculate on the preoperative hyperhomocysteinemia as an independent risk factor for anterior ischemic optic neuropathy...

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 thickness. METHODS: 31 chronic NAION (>6 months after the acute event) and unaffected fellow eyes (31 subjects), 42 moderate and severe POAG eyes (27 subjects), and 77 control eyes (46 healthy subjects) were imaged with a commercial optical coherence tomography angiography system (AngioVue, Avanti RTVue-XR, Optovue, CA) at two academic institutions...

Retinal ischemic injuries play an important role in the pathogenesis of several eye disorders. Inflammation and oxidative stress are key players in ischemic injuries. Following retinal ischemia, vascular endothelial cells and leukocytes express several inflammatory adhesion receptors, such as selectins and cell adhesion molecules. P-selectin stimulates leukocyte recruitment to platelet aggregates and has an important role in vascular homeostasis and inflammatory leukocyte extravasation. Soluble P-selectin can be neuroprotective through competitive binding to the receptors of endogenous P-selectin molecules...

SIGNIFICANCE: Large-vessel giant cell arteritis (GCA) can be a diagnostic dilemma for the eye care provider because it may not involve the typical cranial arteries. When any of its potential ocular complications are diagnosed, it is important to consider this unusual form of GCA. PURPOSE: To report an unusual ophthalmic presentation of large-vessel GCA with sequential bilateral anterior ischemic optic neuropathy and branch retinal artery occlusion. METHODS: A 65-year-old previously healthy woman experienced sequential bilateral anterior ischemic optic neuropathy with branch retinal artery occlusion in the absence of other signs and symptoms suggestive of cranial GCA...
