Persistent indocyanine green angiographic findings in multiple evanescent white dot syndrome.
This report describes unique findings of persistent peripapillary and posterior pole hypofluorescence on indocyanine green angiography (ICGA) in multiple evanescent white dot syndrome (MEWDS). A 38-year-old woman experienced a sudden decrease of visual acuity in the left eye. Multiple white lesions were seen on fundus examination. Fluorescein angiography, indocyanine green angiography, and automated perimetry were performed. Fundus appearance and fluorescein angiography were consistent with the diagnosis of MEWDS. Automated perimetry revealed an enlarged blind spot. ICGA revealed a zone of hypofluorescence surrounding the optic disc and throughout the posterior pole. The enlarged blind spot resolved after seven weeks along with the signs and symptoms of MEWDS. Nine months after initial presentation, ICGA revealed persistent peripapillary and posterior pole hypofluorescence. Resolution of the enlarged blind spot and return of vision does not completely correlate with the disappearance of hypofluorescent areas on ICGA. These findings suggest that MEWDS may result in persistent abnormalities in choroidal circulation even after clinical symptoms resolve.
