Baseline ocular biometrics in children with orthokeratology-induced axial length reduction or elongation.

ABSTRACT:

Purpose

To determine the baseline ocular biometrics in children with axial length reduction after orthokeratology for better myopia control.

Methods

Changes in ocular parameters in 164 subjects who completed one year of Ortho-K treatment were retrospectively reviewed. The subjects were divided into AL reduction (n = 105, ≤ 0 mm/year axial growth) and AL elongation (n = 59, ≥ 0.4 mm/year axial growth) groups based on 1-year axial length changes.

Results

Compared with those in the AL elongation group, children in the AL reduction group were older (p < 0.001), had a higher degree of myopia(p < 0.001), larger pupil diameter (p < 0.001), deeper anterior chamber depth (p = 0.007), and lower corneal endothelial density (p < 0.001). In the AL reduction group, the reduction wa
