Coronavirus disease 2019 (COVID-19) has affected more than 130 million people as of April 2021. During the current pandemic, SARS-CoV-2 been found to cause conjunctivitis with anecdotal evidence a wide range manifestations from scleritis retinitis, occlusive vasculitis and optic neuritis. The purpose this study is raise awareness about possible COVID-19 related ocular manifestations, including ...

Encephalitis has been included in the causes of optic neuritis, but post encephalitic optic neuritis has been rarely reported. Majority of the cases of optic neuritis are either idiopathic or associated with multiple sclerosis, especially in western countries. This is very important in the Asian population where the incidence and prevalence of multiple sclerosis is not as high as in the Western...

In multiple sclerosis, microstructural damage of normal-appearing brain tissue is an important feature of its pathology. Understanding these mechanisms is vital to help develop neuroprotective strategies. The visual pathway is a key model to study mechanisms of damage and recovery in demyelination. Anterograde trans-synaptic degeneration across the lateral geniculate nuclei has been suggested a...

Post-mortem ganglion cell dropout has been observed in multiple sclerosis; however, longitudinal in vivo assessment of retinal neuronal layers following acute optic neuritis remains largely unexplored. Peripapillary retinal nerve fibre layer thickness, measured by optical coherence tomography, has been proposed as an outcome measure in studies of neuroprotective agents in multiple sclerosis, ye...

Dear Editor, Optic neuritis is the most common inflammatory optic neuropathy affecting young adults [1]. Less commonly, optic neuritis may be associated with systemic autoimmune disease, of which Behçet’s syndrome is an extremely rare cause, with only 20 identified cases to date [2]. To the best of our knowledge, there have been no reports in Korean patients. Herein, we report a patient present...

PURPOSE Histopathologic studies have reported retinal nerve fiber layer (RNFL) thinning in various neurodegenerative diseases. Attempts to quantify this loss in vivo have relied on time-domain optical coherence tomography (TDOCT), which has low resolution and requires substantial interpolation of data for volume measurements. We hypothesized that the significantly higher resolution of spectral-...

inconclusive because of small sample size. In the 1980s, the Optic Neuritis Treatment Trial was developed to evaluate corticosteroid treatment for optic neuritis. This multicenter randomized clinical trial, supported by the National Eye Institute, was designed to answer the following questions: (1) Does treatment with either oral prednisone or intravenous methylprednisolone followed by oral pre...

Background: Isolated relapsing optic neuropathy is a recurrent painful optic nerve inflammation without any sign of other demyelinating diseases such as multiple sclerosis (MS) or neuromyelitis optica (NMO) spectrum disorders, and the attacks are purely responsive to steroid therapy. Methods: Recurrent isolated optic neuritis (RION) was diagnosed in patients who presented with at least two diss...

BACKGROUND Numerous case reports have suggested a possible association between optic neuritis and receipt of several different vaccines. The most frequently identified vaccines associated with optic neuritis in the literature are influenza and hepatitis B, and a report describing 2 US military cases suggests an association with the currently used anthrax vaccine (anthrax vaccine adsorbed).
