Multiple evanescent white dot syndrome (MEWDS) is a benign acquired disorder1 that has been linked to the syndrome of acute idiopathic blind-spot enlargement.2 Recently, indocyanine green angiography (ICGA) was used in two patients with MEWDS and revealed multiple small foci of choroidal lesions located mainly at the posterior pole.3 These choroidal lesions outnumbered both the visible retinal white spots and the lesions seen on fluorescein angiography. We investigated with ICGA a patient with MEWDS who exhibited a marked enlargement of the blind spot.
Report of a Case.
A healthy 24-year-old woman experienced the sudden onset of photopsia in her right eye. She also complained of a temporal scotoma perceived as a "black spot" during daytime and a "yellowish spot" with the eyes closed or at night. On April 25,1994, 4 days after the onset of symptoms, visual acuity was 20/40 OD and 20/50 OS, which was amblyopic
