# Unilateral Optic Neuritis Post-COVID-19 Infection: A Case Report

## TL;DR

A young woman developed optic neuritis after a COVID-19 infection, showing the need to recognize such neurological complications.

## Contribution

This case report documents a rare neuro-ophthalmic complication of COVID-19 and its successful treatment with corticosteroids.

## Key findings

- Unilateral optic neuritis was diagnosed shortly after confirmed SARS-CoV-2 infection in a previously healthy individual.
- Clinical improvement was observed following corticosteroid therapy.
- Ultrasound in the emergency department aided in the timely diagnosis of optic neuritis.

## Abstract

COVID-19 has affected millions of individuals worldwide, yet the neuro-ophthalmic consequences among survivors remain incompletely characterized. In this case report, we describe a case of unilateral optic neuritis identified in the emergency department using ultrasound in a previously healthy young woman shortly after confirmed SARS-CoV-2 infection. This case highlights the importance of recognizing neuro-ophthalmic sequelae of COVID-19, outlines the diagnostic evaluation, and demonstrates clinical improvement with corticosteroid therapy.
