Longitudinal Evaluation of Static and Dynamic Accommodation in Young Children.

ABSTRACT:

Purpose

To evaluate longitudinal (3 years) accommodation responses (ARs) in children at high risk (HR) or low risk (LR) for myopia, including a subgroup of children who developed myopia.

Methods

Accommodation was measured in young children (n = 92; 7.54 ± 0.97 years) with functional emmetropia (+0.97 ± 0.54 D) at baseline under static and dynamic conditions using an open-field autorefractor. Linear mixed models assessed group differences and the predictor role of accommodation on myopia onset.

Results

At baseline and all visits (7 total), the LR group showed greater static AR (P < 0.01) and dynamic amplitude (P < 0.01); these effects remained after adjusting for age (AR P = 0.02; amplitude P = 0.01). After further adjusting for refractive error (spherical equivalent o
