Unilateral inferior altitudinal visual field defect related to COVID-19

Ocular manifestations of COVID-19 are still being studied. Posterior segment involvement in viral entities is either direct viral involvement or a delayed immune response to the antigen. A 22-year-old woman presented with history of perceiving absolute inferior scotoma in the right eye for 4 days and history of fever and sore throat 10 days ago. Fundus examination revealed disc edema and vessel tortuosity. Humphreys Field Analyzer confirmed inferior field defect and Optical Coherence Tomography showed superior, nasal and inferior retinal nerve fiber layer thickening in the right eye. Patient was positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) by reverse transcription polymerase chain reaction (RT-PCR) testing. Patient received three doses of injection methylprednisolone over 3 days. There was subjective resolution of scotoma reported 3 weeks posttreatment. We bring forward the first reported case of parainfectious optic neuritis associated with COVID-19.
