Abstract Details

Purpose:

Advances in anterior segment optical coherence tomography have enabled the detailed biometry from the corneal surface to the whole lens. This study was undertaken to analyze the ocular biometric components (OBCs) of hyperopic and myopic children.

Setting:

A cross-sectional study at the ophthalmology department, Kyorin University School of Medicine, Japan.

Methods:

OBCs of hyperopic and myopic children were analyzed with special reference to the architecture of the anterior segment. We examined 22 hyperopic children (44 eyes) with a spherical equivalent (SE) ≥ +2.0 D, and 20 myopic children (39 eyes) with a SE ≤ -1.25 D. The OBCs were measured using ocular biometry (OA2000) and anterior segment swept-source optical coherence tomography (CASIA2). Each component of OBCs was compared with the SE, and their relationships were assessed by statistical analysis.

Results:

The anterior chamber depth, curvature radius of the lens, vitreous chamber length, and the axial length (AL) were negatively associated with the SE with statistical significance (p<0.05). Of these parameters, AL was strongly associated with the SE (correlation coefficient: -0.91). Meanwhile, the lens thickness and corneal curvature radius were positively associated with the SE (correlation coefficient: 0.39 and 0.28, respectively).

Conclusions:

Our results confirm that the main determinants of refractive error (RE) are the AL, However, it is likely that the OBCs of the anterior segment slightly augment the RE. [Conflict of interest: none]
