INTRODUCTION Pseudo-Foster Kennedy syndrome is a triad consisting of ipsilateral optic atrophy, contralateral optic disc edema, and ipsilateral anosmia in the absence of an intracranial mass. Vitamin B12 plays an important role in DNA synthesis, and its deficiency causes peripheral neuropathy, myeloneuropathy, and, very rarely, optic neuropathy. CASE PRESENTATION In this study, we describe a ...

To report a case of anterior ischemic optic neuropathy (AION) following COVID-19 vaccination and provide systematic review all published cases vaccination. A literature search was performed using PubMed Ovid MEDLINE for Terms used in the included “COVID-19 vaccination”, “optic neuropathy”, neuritis”, “ischemic neuropathy”. Titles abstracts were initially screened then full texts eligible studie...

A 57-year-old woman experienced bilateral acute ischemic optic neuropathy after spine surgery. Routine MR imaging sequence, T2-weighted image, showed subtle high signal intensity on bilateral optic nerves. A contrast-enhanced T1 weighted image showed enhancement along the bilateral optic nerve sheath. Moreover, diffusion-weighted image (DWI) and an apparent diffusion coefficient map showed mark...

Optic disc drusen (ODD) are calcific deposits that form in the optic nerve head secondary to abnormalities in axonal metabolism and degeneration. Anterior ischemic optic neuropathy, central retinal artery, and vein occlusion are among the rare vascular complications of disc drusen. We reported the clinical course of a 51-year-old patient with a unilateral acute nonarteritic anterior ischemic op...

Background: Diabetes, low nighttime blood pressure, and nonarteritic ischemic optic neuropathy may be associated. Not too many studies present whether this relationship applies to patients. Objective: Diabetes mellitus, pressure at night, were studied in a group of individuals. Methods: The ophthalmology clinic will conduct cross-sectional research on patients with from March 2019 December 2021...

BACKGROUND To describe the systemic and visual characteristics and prognosis in patients with nonarteritic ischemicoptic neuropathy (NAION) undergoing different treatments. METHODS Retrospective chart review was performed in Kaohsiung Veterans General Hospital patients from 1995-2005 with a clinical diagnosis of NAION, including nonarteritic anterior ischemic optic neuropathy and posterior is...

OBJECTIVE To demonstrate the development of subfoveal fluid associated with optic disc swelling from nonarteritic anterior ischemic optic neuropathy. METHODS Optical coherence tomographic studies obtained during a 3-year period (October 1, 2003, to December 30, 2006) from 76 patients who developed ischemic optic neuropathy from 2 institutions were evaluated. The presence or absence, and the d...

BACKGROUND Nonarteritic ischemic optic neuropathy affects the anterior portion of the optic nerve and is characterized by sudden, painless visual loss. The affected eye has a relative afferent pupillary defect. The typical funduscopic appearance includes optic disc edema, with associated nerve fiber layer hemorrhage. Risk factors include advanced age, systemic hypertension, nocturnal hypotensio...
