Objective To observe the clinical and fundus angiography characteristics of multiple evanescent white dot syndrome (MEWDS). Methods Forty eyes of 40 patients (12 males/28 females) with MEWDS, diagnosed by fundus fluorescein angiography (FFA) or indocyanine green angiography (ICGA) were enrolled. All cases were unilateral. The age was ranged from 16 to 64 years old, with a mean of 29.4 years. The initial average corrected vision was ranged from 0.1 to 1.0, with a mean of 0.82. The characteristics of clinical manifestations, the features of FFA and ICGA were analyzed.Results Multiple graywhite dots (100-500  mu;m) were found throughout the posterior pole and the mid-periphery areas. The lesions were at the depth of outer retina and retinal pigment epithelium layers. Some patients presented with mild vitreous opacity. FFA showed round or ring hyper-fluorescence spots at the early stage and tissue staining at the late stage, corresponding to the gray-white dots. Hyper-fluorescence spots and leakages at the retinal veins near optic disk were seen in 18 patients. The hyper-fluorescence spots near macular area were found in 7 patients. ICGA showed that numerous dark hypo-fluorescent dots in the mid-periphery and posterior pole at the early stage and no leakage at the late stage. ICGA detected more lesions than FFA. All of the patients were recovered without any visual complications within 6-8 weeks. Conclusions MEWDS patients have multiple fundus gray-white dots, and hyper-fluorescence and the abnormal retinal vessels by FFA, and multiple weak hypo-fluorescent spots throughout the posterior pole and the mid-periphery areas clearly on ICGA. The ICGA showed more lesions than the ophthalmoscope and FFA examination.
