Multiple Evanescent White Dot Syndrome (MEWDS) is an eye disorder that was first described by L M Jampol et al. in 1984.

Patients commonly present with acute unilateral painless decreased vision and photopsias. Presentations like central or paracentral scotoma, Floaters and dyschromatopsia are less common. An antecedent viral prodrome occurs in approximately one-third of cases. Myopia is commonly seen in patients. Eye exam during the acute phase of the disease reveals multiple discrete white to orange spots at the level of the RPE or deep retina, typically in a perifoveal location (around the fovea).

The causes are unknown.
