Transient multifocal electroretinogram dysfunction in multiple evanescent white dot syndrome.
A 22-year-old female patient with acute monocular scotomata after an upper respiratory infection and the fluorescein angiographic findings consistent with the diagnosis of multiple evanescent white dot syndrome (MEWDS) is described. Unlike full-field ERG, which shows a generalized depressed signal in MEWDS, the authors showed areas of depressions corresponding to the scotomata using multifocal electroretinogram (MFERG). The MFERG abnormalities seen at presentation resolved with the resolution of clinical symptoms after 6 weeks, in contrast to a previous report. The MFERG may be a useful tool to further characterize MEWDS and other blind-spot enlarging syndromes.
