In the present study of a convenience sample of patients scheduled to have cataract surgery, using linear mixed-effect regression models, we found Hispanics have the smallest LP and RLP and Asians have the second smallest LP and RLP while having the greatest lens thickness (LT) value (Table 1). The LP of Whites was greater than all other racial groups (P<0.05 for all comparisons) and the RLP was greater than other races as well. Our findings may help provide anatomic insight into the relative risk for PACG among different ethnic groups and the potential efficacy of cataract surgery on IOP in these different groups.
