Optic Disc Coloboma May Trigger Multiple Evanescent White Dot Syndrome: Expanding the Clinical Spectrum

Purpose: In this article, we reported a case of secondary multiple evanescent white dot syndrome (MEWDS) that occurred in a patient with optic disc coloboma Methods: A case report Results: A 23-year-old otherwise healthy man experienced decreased vision and photopsia in the right eye for one month. He reported poor visual acuity in the left eye because of refractive amblyopia. His best-corrected visual acuity was 20/100 in the right eye and 20/80 in the left eye. An examination of the right eye showed that the patient had optic disc coloboma. The results of multimodal imaging indicated MEWDS in the right eye. The patient was observed for four weeks. The MEWDS lesions improved, as determined by multimodal imaging, and his best-corrected visual acuity improved to 20/20 in the right eye. Conclusion: Reports of secondary MEWDS have increased, and optic disc coloboma may trigger a MEWDS-like reaction.
