Relative Myopic Defocus in the Superior Retina as an Indicator of Myopia Development in Children.

ABSTRACT:

Purpose

To investigate the role of peripheral refraction in children's myopization.

Methods

This 2-year study included 214 children (8-15 years old). Refraction across the retina (field of view: 60° × 36°) was measured with a custom-made aberrometer every year. Three datasets were established: dataset 1, 214 subjects from baseline to the first-year visit; dataset 2, 152 subjects from baseline to the second-year visit; and dataset 3, 59 initial emmetropes from baseline to the second-year visit. The baseline refraction of different retina regions was correlated with the central myopic shift, and was compared among groups with different levels of myopic shift.

Results

In datasets 1 and 2, the refraction distribution across the retina was significantly different among the
