Abstract

Purpose

To investigate the cross-sectional area (CSA) and thickness of the ciliary muscle and their correlation with accommodative lag in hyperopic anisometropic children.

Methods

Forty children aged between 6 and 10 years with hyperopic anisometropia were recruited. The more hyperopic eye (mean refractive power of 3.51 ± 1.70 D) was compared with the less hyperopic eye (mean refractive power of 0.78 ± 1.41 D). The thickness and CSA of the ciliary muscle were measured with anterior segment optical coherence tomography (OCT) images at four meridians. The differences between the eyes and the correlations between CSA, thickness, axial length and accommodative lag were accessed.

Results

There was no statistically significant difference in CSA between the two groups at any meridian, except at the inferior meridian (P < 0.05). There was no statistically significant difference in ciliary muscle thickness between eyes at any meridian, except on the temporal and the nasal meridians (P < 0.05). There was a significant difference in the ratio of CSA to axial length at all meridians between the two groups (all P < 0.05). Accommodative lag was 1.65 ± 0.55 D and 0.93 ± 0.45 D in the more and less hyperopic eyes, respectively, which was a statistically significant difference (P < 0.05). There was no significant correlation between the CSA with the axial length and the accommodative lag.

Conclusions

This study demonstrated a greater degree of accommodative lag in the more hyperopic eye of anisometropic children. There was no correlation among accommodative lag, axial length and CSA of the ciliary muscle with the degree of hyperopia.
