Children in Tokyo Have a Long Sustained Axial Length from Age 3 Years: The Tokyo Myopia Study.

ABSTRACT:

Background

myopia prevalence is high among Japanese schoolchildren, but the underlying causes are unclear.

Objective

To examine the distributions of ocular biometry and refraction and their associations with lifestyle variables among Japanese schoolchildren.

Methods

This cross-sectional school-based study included 2140 children aged 3-14 years in Tokyo, Japan, and evaluated the distributions under non-cycloplegic conditions and the associated environmental factors.

Results

The prevalence of spherical equivalent (SE) ≤-0.75 diopter among preschoolers (aged 3-6 years), elementary school students (aged 6-11 years), and junior high school students (aged 12-14 years) was 49.7%, 72.4%, and 87.7%, respectively. Multiple linear regression analyses showed that the time
