The crystalline lens lens thickness playing an essential role in maintaining normal visual function, but little attention is paid to the lens thickness. The purpose of this study is to document the normative values of lens thickness (LT) in healthy subjects of Southern China and to evaluate its associated factors. This was a prospective, clinic-based, observational, cross-sectional study. A total of 526 eyes from 263 healthy subjects aged between 5-84 years (mean age, 38.48 ± 22.04 years) were included in the study. All subjects underwent detailed ophthalmic examination, including the measurement of ocular biometric parameters by LenStar LS900. The study focused on LT and its association with general and ocular factors. The generalized estimation equation (GEE) model was used for statistical analysis. The Mean LT was 4.01 ± 0.57 mm(95% CI, 3.97 - 4.06; median, 3.94 mm; range, 3.10 - 5.36). In a univariate regression analysis, the LT was associated significantly age, body weight, body height, body mass index (BMI), systolic pressure, diastolic pressure, spherical equivalent (SE), intraocular pressure (IOP), anterior chamber depth (ACD) and axial length (AL) (all PPPP |
