Ocular dimensions are important in the refractive status of the eye.
The aim of this study is to determine the effect of age and gender on ocular axial dimensions of emmetropic Nigerian Children.
A cross-sectional study of 468 children from selected pre-nursery, nursery and primary schools with normal visual acuity were recruited into the study. Lens thickness (LT), anterior chamber depth (ACD) and vitreous chamber depth (VCD) were measured using a B-mode CLEA Vue 550 PHILLIP ultrasound Machine 2013 model, with a 4-12 MHz linear transducer. Results were entered into the personal computer and analysed using the SPSS statistical package version 21.
There were 235 boys (50.2%) and 233 girls (49.8%) with a ratio of 1.01: 1. Mean age for the study participants as a whole, 8.81 ± 3.81 years. The mean ACD, LT, and VCD were 3.6 mm, 3.7 mm and 17.5 mm in the RE and 3.7 mm, 3.8 mm and 24.8 mm in the LE. Only LT showed a significant difference between the sexes in both eyes. All ocular dimensions increased with age with the exception of ACD in the left eye.
Of all the ocular dimensions, only LT showed the effect of gender, but no effect of age and age groups, particularly on the left eye.
眼部尺寸对眼睛的屈光状态很重要。
本研究的目的是确定年龄和性别对正视的尼日利亚儿童眼部轴长尺寸的影响。
一项横断面研究，从选定的幼儿园、托儿所和小学招募了468名视力正常的儿童参与研究。使用2013款B型CLEA Vue 550 PHILLIP超声仪，配备4 - 12 MHz线性换能器测量晶状体厚度（LT）、前房深度（ACD）和玻璃体腔深度（VCD）。结果录入个人电脑，并使用SPSS统计软件包21版进行分析。
有235名男孩（50.2%）和233名女孩（49.8%），男女比例为1.01:1。研究参与者的平均年龄为8.81±3.81岁。右眼的平均ACD、LT和VCD分别为3.6 mm、3.7 mm和17.5 mm，左眼分别为3.7 mm、3.8 mm和24.8 mm。只有LT在双眼的性别之间显示出显著差异。除左眼的ACD外，所有眼部尺寸均随年龄增加。
在所有眼部尺寸中，只有LT显示出性别影响，但没有年龄和年龄组的影响，特别是对左眼。
