摘　　要：目的:分析学龄期儿童角膜形态特征,为学龄儿童屈光不正检查、角膜病变及治疗提供参考。方法:纳入2020-03/2023-06于我院眼科门诊就诊的6-12周岁儿童为研究对象,根据SE值不同分为正视组(-0.25 D≤SE≤+0.25 D)、近视组(-6.00 D≤SE<-0.25 D)。采用Pentacam眼前节分析仪测量角膜前后表面平坦曲率(K1)、陡峭屈率(K2)、平均曲率(Km)、曲率半径(Rm)、角膜直径(WTW)、中央角膜厚度(CCT),分析比较正视组与近视组、男生与女生以及不同年龄段儿童的角膜形态差异。结果:正视组儿童角膜前表面Km为42.84±0.61 D、Rm为7.85±0.15 mm,后表面Km为-6.23±0.04 D、Rm为6.77±0.15 mm,WTW为11.89±0.28 mm,CCT为557.77±22.44μm。近视组儿童Km为43.68±0.62 D、Rm为7.72±0.16 mm,后表面Km为-6.49±0.03 D、Rm为6.64±0.17 mm,WTW为12.17±0.27 mm,CCT为553.24±22.23μm。正视组与近视组间角膜形态有差异(均P<0.01)。相关性分析显示,角膜形态与年龄、性别显著相关。结论:学龄期儿童角膜形态并不固定,近视的发生除了与眼轴增长有关外,与角膜形态变化显著相关。AIM:To analyze the corneal morphological characteristics of school-age children,and provide reference for the examination of refractive errors,corneal lesions,and treatment in school-age children.METHODS:Children aged 6-12 years in our hospital from March 2020 to June 2023 were included as the research objects,and they are divided into emmetropia group(-0.25 D≤SE≤+0.25 D)and myopia group(-6.00 D≤SE<-0.25 D)according to spherical equivalent(SE).The flat curvature(K1),steep curvature(K2),mean curvature(Km),radius of curvature(Rm),white-to-white(WTW)and corneal central thickness(CCT)were measured by Pentacam anterior segment analyzer.The corneal morphological differences between the emmetropia group and myopia group,boys and girls and children of different ages were analyzed.RESULTS:In the emmetropia group,the anterior corneal surface Km was 42.84±0.61 D,Rm was 7.85±0.15 mm,the posterior corneal surface Km was-6.23±0.04 D,Rm was 6.77±0.15 mm,WTW was 11.89±0.28 mm,CCT was 557.77±22.44μm;in the myopia group,Km was 43.68±0.62 D,Rm was 7.72±0.16 mm,Km was-6.49±0.03 D,Rm was 6.64±0.17 mm,WTW was 12.17±0.27 mm,CCT was 553.24±22.23μm.There was significant difference in corneal morphology between the emmetropia group and the myopia group(both P<0.01).Correlation analysis showed that corneal morphology was significantly correlated with age and gender.CONCLUSION:The corneal morphology of school-age children is not fixed,and the occurrence of myopia is not only related to the growth of axial length,but also significantly related to the changes of corneal morphology.
