Comparison of anterior ocular segment biometry features and related factors among American Caucasians, American Chinese and mainland Chinese

Abstract

Background: To compare the anterior segment biometric parameters amongst adult American Caucasians, American Chinese and mainland Chinese, in order to determine parameters that may contribute to increased risk for angle closure in Chinese. Design: Cross-sectional clinic-based study Participants: Four gender- and age-matched cohorts included Caucasians, American Chinese, Southern and Northern mainland Chinese. Methods: Anterior segment optical coherence tomography was utilized to image the anterior chamber. Customized software was used to calculate the anterior segment parameters. Main Outcome Measures: Anterior chamber depth, anterior chamber width, lens vault and corneal arc depth. Results:..
