Abstract
PURPOSE: 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. METHOD: Retrospective case documentation with the multimodal imaging. RESULT: 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. CONCLUSION: MEWDS can very rarely recur and thermal laser photocoagulation may be a possible triggering factor.
