Fundus Autofluorescence in Multiple Evanescent White Dot Syndrome

الملخص EN

A patient complained of photopsia and vision loss in the left eye for two days, with visual acuity of 20/32.

Right eye was normal.

Funduscopy revealed foveal granularity and gray-white lesions in the posterior pole, mainly temporal to the fovea.

The lesions (dots and spots), along with a few other areas surrounding them, showed hyperautofluorescence on autofluorescence imaging.

Fluorescein angiogram (FA) depicted some early hyperfluorescent dots with late staining.

Indocyanine green angiogram (ICGA) showed hypofluorescent lesions in a greater number compared with funduscopy, autofluorescence, and FA.

Thirty days later, BCVA was 20/20 in both eyes and the complimentary exams were almost normal, despite an ICGA that showed few small hypofluorescent lesions.

This case supports the hypothesis that the choroidal involvement occurs primarily in MEWDS, with secondary involvement of the RPE and the neurosensory retina.
