Outline of Final Research Achievements

There are few study about eye elongation in Japanese students. Therefore, the purpose of this study is to evaluate the morphological changes of the eye elongation in students' eyes using optical coherence tomography. The subjects of this study are elementary and junior high school students, and measurements was performed annually for seven years. We have done three years of the measurements. The results suggest that there is a large variation in eye elongation and shape of the eye and the variation may affect development and diagnosis of several eye diseases such as myopia and glaucoma.
