Abstract

Purpose
In the present study, an atypical case of multiple evanescent white dot syndrome (MEWDS) was reported, which thewhite dots of acute phase and the pigmented patches of recovery phase appeared on different location.
Case summary
A seventeen years old male with no previous medical history was presented with decreased visual acuity of hisleft eye. On the first visit, his maximum corrected vision was 1.0 in right eye and 0.5 in left eye. The white dots with blurry marginwere noted at the nasal retina on fundus exam. Fundus autofluorescence photography, fluorescein angiography and indocyaninegreen angiography all showed typical foundings of MEWDS. Gradually the vision improved up to 1.0 with maximumcorrection in six weeks, with normalized ellipsoid zone contour. However, multiple panretinal pigmented patches appeared diffusely,not only at nasal, where the previous white spots were noted, but also at temporal. The patient was followed up withoutany medication. Finally, the pigmented lesions were disappeared spontaneously.
Conclusions
During the recovery phase of MEWDS, multiple pigmentations may appear in different part of the retina, where thewhite dots were not presented. However, they were disappeared with recovery of clinical symptoms gradually without anytreatment.
