Same-side recurrence of unilateral multiple evanescent white dot syndrome following the thermal laser...

We report the same side recurrence of multiple evanescent white dot syndrome (MEWDS) subsequent to 532 nm laser treatment for the macular neovascularization (MNV) associated with the first MEWDS episode.

Retrospective case documentation with the multimodal imaging.

A 24-year-old otherwise healthy woman who was diagnosed as having left MEWDS four years ago was re-examined for a visual disturbance of the duration of one month in the same eye. Fundus evaluation led us to the diagnosis of left extrafoveal inflammatory MNV. Surprisingly, she developed further visual deterioration a month following the uneventful 532 nm laser photocoagulation in her left eye. Fundus examination and multimodal imaging tests confirmed the recurrent MEWDS after full negative laboratory work-up. Visual acuity and fundus changes were improved with the help of a short course oral steroid therapy.

MEWDS can very rarely recur and thermal laser photocoagulation may be a possible triggering factor.
