Abstract
Purpose :
To investigate the sex-related differences and the association in axial length, anterior chamber depth and lens thickness in elementary school students’ eyes.
Methods :
Prospective cross-sectional observational study of 108 right eyes in healthy Japanese young 54 boys and 54 girls (age 8 or 9 years). Axial length, anterior chamber depth and lens thickness were measured with OA-2000 (TOMEY, Japan). The sex-related differences and the association in axial length, anterior chamber depth and lens thickness were investigated using Welch’s t-test and linear regression analysis.
Results :
The axial length was significantly longer in boys (23.71 ± 0.81 mm) than in girls (23.17 ± 0.92 mm) (p=0.001). The anterior chamber depth was significantly shallower in girls (3.53 ± 0.25 mm) than in boys (3.71 ± 0.22 mm) (p=0.001). There was no significantly difference in lens thickness between boys (3.53 ± 0.81 mm) and girls (3.56 ± 0.19 mm) (p=0.63). The anterior camber depth (R=0.63, 0,56, p<0.001) and lens thickness (R=-0.54, -0.59, p<0.001) were significantly associated with axial length in boys and girls.
Conclusions :
In elementary school students, there was significantly difference in axial length and anterior chamber depth between boys and girls. The anterior chamber depth was significantly positively associated with axial length and the lens thickness was significantly negatively associated with axial length in boys and girls.
