This is the first population based study on ocular biometric measurements (OBMs) conducted in Malaysia. Its objective is to measure and compare among children of different ethnicity who have myopia and emmetropia. Subsets of children aged between 7 and 8 years old who participated in a larger population based refractive error study had their axial length, anterior chamber depth, lens thickness and vitreous depth measured using A scan and vertical and horizontal corneal curvature measured using an autokeratorefractometer. Eighty eight of the 870 children (10.1%) examined had myopia. Boys, Chinese and children with myopia had significantly longer axial length and vitreous depth compared to girls, Malay and Indian and children who were emmetropic respectively. Girls and children with myopia had steeper corneal curvature. The baseline OBMs in Malaysian children of different ethnicity are valuable for studies in myopia progression. Like other studies, children with myopia have longer axial length (P <0.001). and vitreous depth (P <0.001) compared to children who are emmetropia (without myopia).
这是在马来西亚进行的第一项基于人群的眼部生物测量（OBM）研究。其目的是测量和比较患有近视和正视眼的不同种族儿童。参与一项更大规模基于人群的屈光不正研究的7至8岁儿童子集，使用A型超声测量其眼轴长度、前房深度、晶状体厚度和玻璃体深度，并使用自动角膜验光仪测量垂直和水平角膜曲率。在接受检查的870名儿童中，88名（10.1%）患有近视。与女孩、马来人和印度人以及正视眼儿童相比，男孩、华裔和患有近视的儿童分别具有显著更长的眼轴长度和玻璃体深度。女孩和患有近视的儿童角膜曲率更陡。不同种族马来西亚儿童的基线OBM对近视进展研究具有重要价值。与其他研究一样，患有近视的儿童与正视眼（无近视）儿童相比，眼轴长度更长（P<0.001），玻璃体深度更长（P<0.001）。
