本研究では東京・ブラジルで疫学調査を実施し、東京の小・中学生の近視/強度近視有病率が76.5%/4.0%・94.9%/11.3%であったことを報告（E Yotsukura E, Torii H, et al. JAMA Ophthalmology. 2019）、ブラジルの学童ではそれぞれ20.4%/0.48%であったことも報告、さらに日中のバイオレットライト放射照度が東京とブラジルでは異なり、人種差だけでなく、光環境の違いも近視有病率に影響を与えている可能性を報告（Yotsukura E, Torii H, et al. J Clin Med. 2020）した。
Epidemiological studies were conducted in Tokyo and Brazil to understand the prevalence of myopia in modern school children. The prevalence of myopia/high myopia in Tokyo was 76.5%/4.0% in elementary school students, 94.9%/11.3% in junior high school students (E Yotsukura E, Torii H, et al. JAMA Ophthalmology. 2019). Furthermore, in Brazil, the prevalence of myopia and the light environment were investigated, and the prevalence of myopia/high myopia in school children was 20.4%/0.48%. It is reported that not only racial differences but also differences in light environment may affect the prevalence of myopia (Yotsukura E, Torii H, et al. J Clin Med. 2020).
