Purpose: To determine the distribution of refractive errors in Japanese patients with multiple evanescent white dot syndrome (MEWDS) and compare them with age-matched controls. MEWDS is an acute, multifocal, usually unilateral retinopathy, that mainly occurs in young female patients. Methods: Forty-six Japanese patients with MEWDS (10 men and 36 women; ages, 15-58, mean 30.6 years) were studied. Ten patients were seen at the Nagoya University Hospital and thirty-six patients were previously reported in Japanese Journals of Ophthalmology. The refractive errors (spherical equivalent) in the patients were compared with that in 138 age-matched controls. Results: The mean refractive error in the patient group was –5.21±4.68 diopters (D) which was significantly greater than that in the controls (-2.76±3.04 D, P = 0.001). Nineteen of 46 (41.3%) MEWDS patients had refractive error more than –6.00 D, whereas 17 of 138 normal subjects (12.3%) had this degree of myopia, and this difference was statistically significant (P = 0.005). Conclusions: Myopia is commonly found in Japanese patients with MEWDS.
