Multiple evanescent white dot syndrome.

Multiple small infiltrates deep in the retina were found in three previously healthy patients aged 21-28 years in association with a mild non-specific acute infection. In two patients the lesions were uniocular, in one patient both eyes were affected. Both posterior pole and midperiphery were involved. In two cases the optic disk was slightly swollen. Due to macular lesions the visual acuity on admission varied from 0.1 (6/60) to 0.6 (6/10). On fluorescein angiograms the lesions were initially hypofluorescent and later slightly hyperfluorescent. No causative agents were discovered. All lesions resolved in 4-8 weeks without treatment, leaving faint pigment dispersion or, more commonly, no visible scars, and the visual acuity recovered to 1.0 (6/6).
