Multiple evanescent white dot syndrome following COVID-19 infection: A case report

Abstract

Multiple evanescent white dot syndrome (MEWDS) is typically a unilateral and transient condition without an exact known underlying cause. Its pathogenesis may involve an immune response to viral antigens that have gained access to the retinal receptor cells. It has been hypothesized that the COVID-19 virus can activate some autoimmune responses. Here, we report a case of MEWDS in a 16-year-old girl with a history of COVID-19 infection two weeks before the visual symptoms. The symptoms and signs improved without any treatment after a three-month follow-up period. In our case, MEWDS occurred shortly after COVID-19 infection and resolved without treatment in three months. Considering ophthalmologic and immunologic associations of COVID-19 can help ophthalmologists in the diagnosis and treatment of similar disorders in the COVID-19 era.
