摘要
目的:分析高度散光儿童眼前节生物学参数的特征。方法:系列病例研究。收集2020年10月至2021年10月就诊于河南省儿童医院的散光患儿82例(82眼),其中高度散光患儿64例(散光≥2.00 DC),中低度散光患儿18例(散光<2.00 DC)。采用SIRIUS天狼星三维角膜地形图及眼前节分析系统测定患儿眼前节生物学参数,包括角膜参数和前房参数。角膜参数包括角膜最薄点厚度、角膜最薄点位置、中央角膜厚度、角膜体积、角膜前后表面K1、角膜前后表面K2、角膜前后表面球镜度、角膜前后表面柱镜度、光学区4 mm球镜度、光学区4 mm柱镜度;前房参数包括前房深度、水平虹膜直径、虹膜角膜夹角、前房直径。采用独立样本t检验、单因素方差分析等方法对眼前节各生物学参数进行统计学分析。结果:高度散光组儿童与中低度散光组相比,前房参数、角膜厚度和角膜体积差异均无统计学意义,2组角膜最薄点位置分别有97%和89%位于颞下方,高度散光组角膜前、后表面K1值较低(t=-2.61,P=0.011;t=2.40,P=0.019),角膜前、后表面散光及光学区4 mm散光度数较大(t=-11.00,P<0.001;t=5.58,P<0.001;t=-10.25,P<0.001)。散光程度较高组,前房直径较大,2组差异具有统计学意义(F=3.03,P=0.036)。高度散光组屈光状态转化为等效球镜度,等效球镜度越小,前房深度和房角越大,组间差异具有统计学意义(F=11.12,P<0.001;F=5.07,P=0.009)。结论:高度散光组儿童的角膜前后表面散光及光学区4 mm散光较大,角膜最薄点位置大多位于颞下方,角膜前后表面K1值较低,散光程度较高组儿童,前房直径较大,高度散光组等效球镜度越小,前房深度和房角越大。
Objective:To analyze the characteristics of biological parameters of anterior segment in children with high astigmatism.Methods:In this case-series study.A total of 82 cases with 82 eyes of children with astigmatism in Henan Children's Hospital from October 2020 to October 2021 were collected,including 64 children with high astigmatism(astigmatism≥2.00 DC),and 18 children with moderate to low astigmatism(astigmatism<2.00 DC).Use SIRIUS three-dimensional corneal topography and anterior segment analysis system to determine the biological parameters of cornea and anterior chamber.Corneal parameters include corneal thinnest point thickness,corneal thinnest point position,central corneal thickness,corneal volume,corneal anterior and posterior surface K1,corneal anterior and posterior surface K2,corneal anterior and posterior surface spherical lens,corneal anterior and posterior surface cylindrical lens,optical zone 4 mm spherical lens,optical zone 4 mm cylinder;anterior chamber parameters include anterior chamber depth,horizontal iris diameter,iris corneal angle,and anterior chamber diameter.The biological parameters of the anterior segment were statistically analyzed by independent samples t test and one-way ANOVA.Results:There were no significant differences in anterior chamber parameters,corneal thickness and corneal volume between the high astigmatism group and the moderate-low astigmatism group.In the two groups,97%and 89%of the corneal thinnest points were located in the inferior temporal area,respectively,the K1 value of the anterior and posterior corneal surfaces of the high astigmatism group was lower(t=-2.61,P=0.011;t=2.40,P=0.019),and the astigmatism of the anterior and posterior corneal surfaces and the 4 mm astigmatism of the optical zone were larger(t=-11.00,P<0.001;t=5.58,P<0.001;t=-10.25,P<0.001).Children in the higher astigmatism group had larger anterior chamber diameter,and the difference between the groups was statistically significant(F=3.03,P=0.036).The refractive state of the high astigmatism
