PURPOSE: To assess the correlation of carotid artery intimal medial thickness (C-IMT) and carotid artery plaque score (CPS) of the common carotid artery with non-arteritic anterior ischemic optic neuropathy (NAION) in hypertensive patients. METHODS: This case-control study recruited 192 subjects. Forty-eight patients had NAION with systemic hypertension, 46 had hypertension without visual complaints, and 98 were normal controls. C-IMT and common carotid arterial plaque were measured by high-resolution vascular ultrasonography...

Normal tension glaucoma (NTG) also known as low tension glaucoma, presents with optic nerve head and visual field damage in the absence of high intraocular pressure (<21 mmHg). There are several patients of NTG seen in our clinics who have repeatable visual field defects, which may or may not correlate with the disc appearance, but are labeled as glaucoma. Ruling out ischemic, nutritional, and other causes of one-time damage are important before diagnosing an NTG. We report 3 such cases that were misdiagnosed and referred as NTG...

Shakoor Ba-Ali, Henrik Lund-Andersen
In recent years, chromatic pupillometry is used in humans to evaluate the activity of melanopsin expressing intrinsic photosensitive retinal ganglion cells (ipRGCs). Blue light is used to stimulate the ipRGCs and red light activates the rod/cone photoreceptors. The late re-dilation phase of pupillary light reflex is primarily driven by the ipRGCs. Optic neuropathies i.e. Leber hereditary optic neuropathy (LHON), autosomal dominant optic atrophy (ADOA), nonarteritic anterior ischemic optic neuropathy (NAION), glaucoma, optic neuritis and idiopathic intracranial hypertension (IIH) are among the diseases, which have been subject to pupillometric studies...

BACKGROUND: Although peripheral nervous system involvement is common in eosinophilic granulomatosis with polyangiitis (EGPA), central nervous system (CNS) manifestations are poorly described. This study aimed to describe CNS involvement in EGPA. PATIENTS AND METHODS: This retrospective, observational, multicenter study included patients with EGPA and CNS involvement affecting cranial nerves, brain and/or spinal cord. We also undertook a systematic literature review...

Purpose: To compare optical coherence tomography angiography (OCT-A) retinal vasculature measurements between nonarteritic anterior ischemic optic neuropathy (NAION) and open angle glaucoma (OAG) with altitudinal hemifield visual field defects. Methods: This retrospective cross-sectional study included 10 NAION eyes and 16 OAG eyes, both demonstrating hemifield visual field defects, and 27 normal eyes serving as controls. The peripapillary and macular OCT-A scans were acquired...

As a Traditional Chinese Medicine, compound anisodine (CA) has previously been shown to regulate the vegetative nervous system, improve microcirculation and scavenge reactive oxygen species, and has been commonly utilized as a neuroprotective agent to treat ischemic optic neuropathy and choroidoretinopathy. The present study aimed to investigate the neuroprotective effects of CA on the proliferation and calcium overload of hypoxia-induced rat retinal progenitor cells (RPCs) and brain neural stem cells (BNSCs) harvested from neonatal Sprague-Dawley rats...

BACKGROUND: To investigate the effect of combined intravenous (IV) erythropoietin (EPO) and corticosteroid as well as systemic steroid alone for the treatment of non-arteritic anterior ischemic optic neuropathy (NAION). METHODS: In this prospective interventional comparative case series, 113 consecutive patients diagnosed with recent onset (less than 14 days) NAION were included. Patients were categorized into three groups. 40 patients received systemic IV corticosteroid combined with recombinant human erythropoietin (rhEPO) (group 1), 43 patients received systemic corticosteroid alone (group 2), and 30 patients were enrolled as the control group (group 3)...

OBJECTIVE: The aim of this study is to clarify the efficacy and safety of early surgery using trapping of the affected internal carotid artery (ICA) and high-flow bypass between second portion of the middle cerebral artery and cervical external carotid artery with radial artery graft for ruptured blood blister-like aneurysms (BBAs) arising from anterior wall of the ICA. METHODS: Medical chart of consecutive 16 patients (M:F=7:9, mean 59 years) with subarachnoid hemorrhage (WFNS grade I:2, II:5, III:2, IV:4, V:3) due to ruptured BBA surgically treated between July 2010 and October 2015 were retrospectively reviewed...

BACKGROUND: Non Arteritic Anterior Ischemic Optic Neuropathy (NAION) is the most common acute optic neuropathy in patients over 50 years of age. This study was conducted to determine the beneficial effects of anticoagulation with Heparin and Warfarin in patients with NAION presenting within 4 weeks of onset of symptoms. METHODS: A prospective, interventional, pilot study was conducted in Eye- A unit of Khyber Teaching Hospital from July 2010 onwards on patients with NAION presenting within 4 weeks of onset of symptoms...

Giant cell arteritis (GCA) is a systemic vasculitis of medium and large arteries often with ophthalmic involvement, including ischemic optic neuropathy, retinal artery occlusion, and ocular motor cranial nerve palsies. This last complication occurs in 2%-15% of patients, but typically involves only 1 cranial nerve. We present 2 patients with biopsy-proven GCA associated with multiple cranial nerve palsies.

BACKGROUND: The optic nerve head is vulnerable to ischemia leading to anterior ischemic optic neuropathy (AION), the most common acute optic neuropathy in those older than 50 years of age. METHODS: We performed a cross-sectional study of 55 nonarteritic anterior ischemic optic neuropathy (NAION) eyes in 34 patients to assess clinical outcome and perform structure-function correlations. RESULTS: The peak age of NAION onset was between 50 and 55 years...

AIM: To evaluate the whether intravitreal erythropoietin (EPO) administration has any beneficial or adverse effect in patients with late-stage optic neuropathy (ON) or not. METHODS: The study examined 16 eyes of 16 patients who had late-stage ON and ≥1/20 best-corrected visual acuity (BCVA) in their affected eye. There were nonarteritic ischemic ON in 10 (62.5%) eyes, traumatic ON in 4 (25.0%) eyes and methanol-induced ON in 2 (12.5%) eyes. Using pars plana approach, 2000 IU/0...

PURPOSE: Critical flicker fusion (CFF) frequency is a well-studied test for evaluating demyelinating optic neuritis (ON). Its use in evaluating other optic neuropathies is not well established. The purpose of this study was to compare CFF in ON and non-arteritic anterior ischemic optic neuropathy (NAION). METHODS: We performed a retrospective review to compare multiple variables for eyes with ON or NAION using two-sided T tests and Chi-square tests. A multivariate linear regression was performed for the dependent variable CFF...

Ocular ischemic syndrome (OIS) is a collection of symptoms of carotid and ophthalmic artery disease of common genesis accompanied by ischemia of eyeball membranes. Specifically, the intraocular blood flow becomes impaired due to inflow reduction or arrest, while the venous outflow remains patent. Causes of OIS include arterial hypertension, atherosclerosis, diabetes, aortoarteritis and other vascular diseases. Clinical features depend on the extent, nature, and site of vascular involvement as well as the concurrent pathology...
