Biometric risk factors for myopia onset in emmetropic school-age children.

ABSTRACT:

Purpose

To identify the potential biometric risk factors for the onset of myopia in emmetropic school-age children.

Study design

Longitudinal study.

Methods

First, we performed a preliminary study in which objective refraction, corneal refractive power, higher-order aberrations (HOAs), and axial length (AL) was measured annually in 98 Grade-3 (age 8) elementary schoolchildren over a 4-year period from 2006 to 2009. We also examined the refractive changes over 3 years, and assessed the correlation between those changes and the baseline data. Based on those findings, we performed the primary study in which objective and subjective refraction, corneal refractive power, HOAs, and AL was measured annually in Grade 1 (age 6) through Grade 8 (age 13) schoolchildren from 2013
