Optic Neuritis In A Patient With Seropositive Myelin Oligodendrocyte Glycoprotein Antibody During The Post-Covid-19 Period

Reports of neuro-ophthalmological manifestations and complications in patients with coronavirus disease 19 (COVID-19) are still scarce. The aim of this article is to present optic neuritis, as possible post-infectious manifestation of COVID-19. Four weeks after hospitalization for seropositive coronavirus disease 19 (COVID-19), presented as bilateral bronchopneumonia, with radiology and laboratory findings also pointed to high clinical suspicion to COVID-19, a 63-year-old man developed a headache and subacute and profound visual loss on his right eye. The disease presentation was the right eye papillitis. Inflammatory parameters were normal at the time of hospitalization, and IgM and IgG for SARS-CoV-2 were still positive. After corticosteroid pulse therapy, his vision improved significantly and on follow-up visits returned to normal. All laboratory and radiology findings were unremarkable, except for antibodies against SARS-CoV-2 and myelin oligodendrocyte glycoprotein (MOG). We discuss about capacity of SARS-CoV-2 to cause optic neuritis and possible significance of MOG antibodies in similar cases.
