ABSTRACT Purpose To report a case of multiple evanescent white dot syndrome (MEWDS) following severe acute respiratory syndrome coronavirus 2 vaccination. Study Design Case report. Results A 36-year-old healthy Taiwanese female was presented with flashing lights in the right eye two days after the first dose of Medigen Vaccine Biologics Corporation (MVC) coronavirus disease 19 (COVID-19) vaccine. Examination of the retina revealed multiple white dots in the posterior pole extending to the mid-periphery. Disruption of ellipsoid zone on optical coherence tomography, early hyperfluorescence on fluorescein angiography, late hypo-cyanescence on indocyanine green angiography, and paracentral scotoma on visual field test were consistent with MEWDS. At four-week follow-up, the patient’s fundus lesions resolved, and symptoms subsided without treatment. Conclusion Resembling previous post-vaccine MEWDs cases, the symptoms are self-limited, and the visual prognosis is excellent. The presented case demonstrates MEWDS following MVC COVID-19 vaccine and suggests the immune-mediated basis for MEWDS in predisposed patients.
