Abstract
Purpose: :
To investigate the sex-related differences and the association in axial length, anterior chamber depth and lens thickness in Japanese young healthy eyes.
Methods: :
Cross-sectional observational study of 98 right eyes in healthy Japanese young 69 men and 29 women. All participants (mean age; men 26.0 ± 3.8, women 25.0 ± 3.7 years) underwent comprehensive ophthalmologic examination. Axial length, anterior chamber depth and lens thickness were measured with AL-2000 ultrasound device (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: :
There was no significantly difference in axial length between men (25.70 ± 1.38 mm) and women (25.11 ± 1.48 mm) (p=0.071). The anterior chamber depth was significantly shallower in women (3.60 ± 0.28 mm) than in men (3.79 ± 0.25 mm) (p=0.003). The lens thickness was significantly thicker in women (3.79 ± 0.22 mm) than in men (3.68 ± 0.26 mm) (p=0.038). The anterior camber depth (R=0.55,p=0.002) and lens thickness (R=-0.43,p=0.021) were significantly associated with axial length in women but not in men.
Conclusions: :
In this study, there was significantly difference in anterior chamber depth and lens thickness between men and women in Japanese young eyes. Only in women, the anterior chamber depth was significantly positively associated with axial length and the lens thickness was significantly negatively associated with axial length.
