Unilateral Optic Neuritis in Post COVID-19: A Case Report

Abstract

Optic Neuritis had been an unusual manifestation, reported in patients affected with Coronavirus disease-2019 (COVID-19). Here the authors report a case of 67-year-old male patient, who got manifested with optic neuritis as post COVID-19 sequelae. He was treated for COVID-19. Later on, after 21 days of treatment, he presented with blurring of vision and diplopia and was further evaluated and diagnosed as a case of optic neuritis with axial Time (T2) Magnetic Resonance Imaging (MRI) scan showing mild thickening and T2 hyperintensity of intracanalicular part of the optic nerve of the right eye. The patient was started on intravenous methylprednisolone followed by oral prednisolone. He had a good visual outcome. Post COVID-19, optic neuritis has become one of the possible neurological complications that may either present with unilateral or bilateral loss of vision. Hence, the clinicians should be aware of neuro-opthalmic involvement and treatment should be initiated promptly for improved outcomes.
