We examined the distribution of intraocular pressure (IOP) and its associated factors in children.
Using a random cluster sampling from kindergartens, primary schools, and junior and senior high schools from rural Guanxian County and the city of Weihai, the school-based cross-sectional Shandong Children Eye Study included children aged 4 to 18 years. All participants underwent an ocular examination, including ocular biometry, cycloplegic refractometry, and noncontact tonometry.
Mean IOP was 17.6 ± 2.7 mm Hg (range, 10-28 mm Hg). The IOP increased up to an age of 10 years and subsequently decreased with older age. In multivariate regression analysis, higher IOP was associated with female sex (P < 0.001; standardized correlation coefficient β, 0.06; regression coefficient β, 0.34; 95% confidence interval [CI], 0.18, 0.50), higher body mass index (P < 0.001; correlation coefficient β, 0.09; regression coefficient β, 0.07; 95% CI, 0.04,0.09), younger age (P < 0.001; correlation coefficient β, -0.15; regression coefficient β, -0.13; 95% CI, -0.17,-0.10), maternal myopia (P < 0.001; correlation coefficient β, 0.05; regression coefficient β, 0.34; 95% CI, 0.15,0.53), and more time spent indoors with reading/writing (P = 0.002; correlation coefficient β, 0.05; regression coefficient β, 0.07; 95% CI, 0.03,0.11), and with the ocular parameters of longer axial length (P < 0.001; correlation coefficient β, 0.14; regression coefficient β, 0.29; 95% CI, 0.21,0.37) and smaller corneal horizontal diameter (P < 0.001; correlation coefficient β, -0.06; regression coefficient β, -0.31; 95% CI, -0.46,-0.15).
In children aged 4 to 18 years, IOP showed an M-shaped association with age. Higher IOP was associated with the nonocular parameters of female sex (P < 0.001), higher body mass index (P < 0.001), younger age (P < 0.001), maternal myopia (P < 0.001), and more time spent indoors with reading/writing (P = 0.002), and with the ocular parameters of longer axial length (P < 0.001) and smaller corneal horizontal diameter (P < 0.001).
我们研究了儿童眼内压（IOP）的分布及其相关因素。
本研究采用多阶段整群抽样方法，从山东省冠县农村地区和威海市的幼儿园、小学、初中和高中抽取了 4 至 18 岁的儿童进行了基于学校的横断面山东儿童眼研究。所有参与者均接受了眼部检查，包括眼生物测量、睫状肌麻痹屈光检查和非接触眼压测量。
平均 IOP 为 17.6±2.7mmHg（范围 10-28mmHg）。IOP 一直升高到 10 岁，然后随着年龄的增长而降低。多变量回归分析显示，较高的 IOP 与女性（P<0.001；标准化相关系数β，0.06；回归系数β，0.34；95%置信区间[CI]，0.18，0.50）、较高的体重指数（P<0.001；相关系数β，0.09；回归系数β，0.07；95%CI，0.04，0.09）、较小的年龄（P<0.001；相关系数β，-0.15；回归系数β，-0.13；95%CI，-0.17，-0.10）、母亲近视（P<0.001；相关系数β，0.05；回归系数β，0.34；95%CI，0.15，0.53）、更多的室内阅读/写作时间（P=0.002；相关系数β，0.05；回归系数β，0.07；95%CI，0.03，0.11）、较长的眼轴（P<0.001；相关系数β，0.14；回归系数β，0.29；95%CI，0.21，0.37）和较小的角膜水平直径（P<0.001；相关系数β，-0.06；回归系数β，-0.31；95%CI，-0.46，-0.15）有关。
在 4 至 18 岁的儿童中，IOP 与年龄呈 M 形关联。较高的 IOP 与女性（P<0.001）、较高的体重指数（P<0.001）、较小的年龄（P<0.001）、母亲近视（P<0.001）、更多的室内阅读/写作时间（P=0.002）、较长的眼轴（P<0.001）和较小的角膜水平直径（P<0.001）等非眼参数有关。
