Abstract
To describe recent cases of optic neuritis in patients who received a vaccine for COVID-19. Retrospective case series of patients diagnosed with optic neuritis after a recent COVID-19 vaccination with BNT162b2 (Pfizer-BioNTech), in one university-affiliated tertiary hospital, from January 2021 to June 2021. Data were obtained from medical charts. We describe 7 patients who developed optic neuritis after immunization with the BNT162b2 vaccine. A causal relationship cannot be deduced, and the importance of COVID-19 vaccination is not challenged. However, the authors encourage a prospective monitoring and reporting system for all patients receiving COVID-19 vaccines, to further assess the spectrum of adverse events in large databases.
