Abstract
Purpose:
To investigate the normative data of lens vault and their associations with ocular and general parameters in Chinese adults.
Methods:
Design: Population-based study. Methods The Beijing Eye Study 2006 included 3251 subjects. The subjects underwent an ophthalmologic examination including measurement of the anterior chamber dimensions by slit-lamp-based optical coherence tomography (SL-OCT). The value of lens vaults (LV), defined as the perpendicular distance between the anterior pole of the crystalline lens and a horizontal line, were got from the pictures of SL-OCT. The multiple linear regression analysis were used to analysis the relationship between LV and ocular and general parameters.
Results:
In an multiple linear regression analysis, the LV was significantly associated with rural or urban district, gender, age, refractive error, IOP, anterior chamber depth, anterior chamber angle, CCT, primary angle closure glaucoma, primary open angle glaucoma, nuclear cataract, cortical cataract, systolic blood pressure and diastolic blood pressure, but not significantly associated with subcapsule cataract, DM, DR, height, weight, body mass index, fasting blood glucose, blood total cholesterol, blood triglyceride, high density lipoprotein and low-density lipoproteins.
Conclusions:
The lens vaults are maybe a important parameters about to evaluate and diagnose primary angle-closure glaucoma.
