2、麻痹前后的电脑验光,记录全眼散光及轴向;ZeissIOLMaster测量眼轴长度。每例均取右眼进行统计分析。对完成所有检查的13080例有效样本的全眼散光进行Thibos矢量分析,将近视性散光转换为M、Jn和J45。睫状肌麻痹前后的各数据差异采用配对t检验进行统计分析。结果睫状肌麻痹前后,3~6岁儿童主要表现为顺规性散光,特别是在柱镜值≥1.00D的高度散光组,其次为斜轴性散光.最后为逆规性散光。在睫状肌麻痹后,高度散光的比例略有下降.从19.96%降至18.41%:而O.25~0.75D的正常散光比例略有增加,从28.
3、59%增加到33.72%。同时在睫状肌麻痹后,顺规性散光比例增高,逆规性散光和斜轴性散光比例都略有下降。而在高度顺规性散光组中,睫状肌麻痹后全眼散光值下降[(一1.612_+0.763)Ds.(一1.457_+0.645)D,=一6.396,P4、ain3-6yearsoldpreschoolchildrenFENGYon—qing,HUANGJia,CHENLu,Shu—qin,ZHANGZhi-jie,HUANGXiao—qian,WANGJia,ZOUco,WANGBei,ZHOUXing-too.YangpuDistrictEyeDiseasePreventionandControlCenter&Departmentofophthalmology,KongfiangHospital,Shanghai200093,ChinaCorrespondingauth5、or:WANGBei,Email:fyq2299@163.com;ZHOUXing-tao,Email:xingtaozhou@163.com【Abstract】ObjectiveAnalyzeastigmatismin3-6yearsoldpreschoolchildrenusingvectoranalysisandtoinvestigatetheeffectofcycloplegiaonastigmatism.MethodsInthiscross—sectionalstudy,refractionandeyeheal6、thwereexaminedin141163-6yearsoldchildren(7310boys,6806girls)inYangpuDistrict,Shanghai,China,fromJanuary2012toOctober2012.Pre—andpost—cycloplegicrefractivemeasurementsweretakenwithanautorefractor(CanonRK—F1,Japan)andaxiallengthwasmeasuredwithanIOLMaster(CarlZeiss,7、Germany).Of13080eligiblechildren,allthedatafromtherighteyeswereanalyzed.MeasurementsofspherocylinderweretransposedintoM,J0andJ45componentsbyFouriertransformation.Datawereanalyzedusingapairedttest.ResultsAstigmatisminpreschoolchildren3-6yearsoldwasmainlywith—the—r8、ule(WTR),especiallyinthehi【ghastigmatismgroup(HAG,≥1.0D),followedbyobliqueaxisastigmatism,andthenagainst—the-rule(ATR)astigmatism.Aftercycloplegia,theprevalenc
