OPTIC DISK COLOBOMA MAY TRIGGER MULTIPLE EVANESCENT WHITE DOT SYNDROME: EXPANDING THE CLINICAL SPECTRUM.

PURPOSE: To report a case of secondary multiple evanescent white dot syndrome (MEWDS) that occurred in a patient with optic disk 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 disk 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 disk coloboma may trigger a MEWDS-like reaction.
