Differences in ocular biometrics and aqueous humour dynamics between Chinese and Caucasian adults

BackgroundGlaucoma prevalence and subtype profile vary across different racial and ethnic groups. This study provides a comparative evaluation of differences in aqueous humour dynamics (AHD) and ocular biometrics in healthy Chinese and Caucasian adults of two different age groups.MethodsData from two independent studies with identical designs were compared. Cohorts included young adults (20–30 years old, 32 Chinese and 39 Caucasians) and older adults (>50 years old, 37 Chinese and 46 Caucasians). Parameters of AHD and ocular biometrics were evaluated. Group comparisons were made by generalised estimating equation methods.ResultsDifferences in young adult Caucasians compared with similarly aged Chinese were thinner central cornea (−29.27 µm, p
