Unilateral Mooren Ulcer After COVID-19 Vaccination

Abstract

Introduction: Mooren ulcer is an immune-related corneal pathology of unknown origin, that often occurs following a triggering factor. Case Report: We report the case of a 32-year-old woman who presented with a red painful right eye. The clinical findings were in favor of peripheral ulcerative keratitis. The etiological assessment came back negative. The retained diagnosis was Mooren ulcer. The treatment was based on oral corticosteroid therapy and immunosuppressants prescribed by internists. The evolution was marked by the regression of the pain and the stability of the lesion. Discussion: Currently in the literature, rare cases of corneal ulcers following COVID-19 vaccination have been described. A causal link remains possible but not yet proven. This subject needs more perspective and research. Conclusion: The COVID-19 vaccine has several ocular side effects. The mechanism of triggering a mooren ulcer remains unclear.
