First proposed by De Wecker! in 1872 as a treatment for neuroretinitis, optic nerve sheath decompression (or fenestration) is an operation that has caused much controversy. This surgical therapy was not seriously considered until Davidson" and Smith, Hoyt, and Newton" reintroduced it in 1969 as an alternative therapy for chronic disk edema. Over the next 19 years, however, only about 60 cases o...

conclusions our case report showed the therapeutic effect of rhepo in complete curing of povl. regarding the side effects of epo such as thrombogenic effects or mild hemodynamic changes like transient sinus tachycardia during infusion, it seems that beneficial effects of epo is more than its disadvantages and expenses, for patients with povl. case presentation our patient was a 61-year-old man,...

BACKGROUND Protein Z is a glycoprotein that acts as a co-factor for the inhibition of activated coagulation factor X. Protein Z circulating in abnormal levels has been associated with increased risk for acute ischemic events. Non-arteritic Anterior Ischemic Optic Neuropathy (N-AION) is caused by acute ischemic infarction of the optic nerve head, supplied by the posterior ciliary arteries. OBJ...

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...
