Angle-closure glaucoma is an anatomical disorder of the anterior segment of the eye characterized by permanent closure of part of the filtration angle. Demographic and anatomical factors play significant roles in the development of angle-closure glaucoma.[21–23] Ethnicity was recognized as a major risk factor for primary angle-closure glaucoma in a comprehensive review of the literature conducted by Congdon et al in 1992, with Asians among those with the highest risk and Whites having substantially lower risk. Previous studies have also shown that greater lens thickness (LT), smaller anterior chamber depth (ACD), and shorter axial length (AL) are risk factors for PACG.[25–29] Recent studies have also shown that LP, RLP, and LT can be predictive for angle closure.[30–32] In this current study of a clinic population, our findings suggest that the position and thickness of a lens may also be significantly different among ethnic groups and help explain the differential risk for angle closure among these groups. Hispanics and Asians had the smallest LP and RLP and the thickest LT among the four major racial groups in our study.
