SureSight检查与睫状肌麻痹验光的相关性研究

Correlation analysis between the optometry measured by SureSight refractometer and retinoscopy with atropine cycloplegia

目的评价学龄前儿童应用SureSight验光仪与阿托品睫状肌麻痹验光结果之间的相关性。方法选取2017年1~12月在北京市海淀区妇幼保健院眼科门诊就诊的2~6岁儿童422例(844眼),其中男199例,女223例,平均年龄(3.12±0.82)岁。分别应用SureSight验光仪和阿托品睫状肌麻痹验光检查屈光度,分析二者的相关性。根据SureSight检查结果将球镜度数分为4组(≤0.00 DS组、+0.25^+2.75 DS组、+3.00^+5.75 DS组和+9.99 DS组),柱镜度数分为4组(-0.75~0.00 DC组、-1.50^-1.00 DC组、-3.00^-1.75 DC组和-9.99 DC组),分别比较各组应用两种检查方法的球镜度和柱镜度的分布差异,并进行相关性分析。比较两种检查方法各组散光轴位符合率。结果SureSight检查结果与睫状肌麻痹验光结果的球镜度、柱镜度具有显著相关性(r=0.59,r=0.85,P均<0.05),柱镜度的相关性更高。分组比较,球镜度为+3.00^+5.75 DS组、+0.25^+2.75 DS组和≤0.00 DS组的两种检查方法具有相关性(r=0.46,r=0.34,r=0.65,P均<0.05)。柱镜度为-0.75~0.00 DC组、-1.50^-1.00 DC组和-3.00^-1.75 DC组的两种检查方法均有相关性(r=0.43,r=0.42,r=0.64,P均=0.00)。两种检查方法散光轴位总体符合率可达88.90%,散光度数越高,符合率越高,差异有统计学意义(χ2=56.12,P=0.00)。SureSight检查球镜度为+9.99 DS者18眼,柱镜度为-9.99 DC者42眼,睫状肌麻痹验光结果均为影响视力发育的严重屈光异常。结论对于屈光异常儿童,SureSight检查与睫状肌麻痹验光具有更高的相关性,SureSight验光仪有助于儿童屈光异常的发现,可用于眼保健工作中大样本儿童屈光状态的筛查。

Objective To observe the correlation between the optometry measured by SureSight refractometer and retinoscopy with 1%atropine cycloplegia for the preschool children.Methods SureSight optometry with noncycloplegia and retinoscopy with 1%atropine cycloplegia were used in 422 cases(844 eyes),their ages were two to six years old.Spherical diopter of SureSight refractometer were divided into four groups[≤0.00 DS,+(0.25-2.75)DS,+(3.00-5.75)DS and+9.99 DS],and cylindrical diopter were divided into four groups[-0.75-0.00 DC,-(1.00-1.50)DC,-(1.75-3.00)DC and-9.99 DC],difference and correlation were analyzed respectively,the astigmatism axis compliance rate of each group was compared with the two methods.Results There was a clear correlation between the two methods,the correlation between cylindrical diopter was higher than that of spherical diopter(r=0.59,r=0.85,P<0.05).There was a moderate positive correlation between the spherical diopter of+(3.00-5.75)DS group,+(0.25-2.75)DS and≤0.00 DS group(r=0.46,r=0.34,r=0.65,all P<0.05).There was a moderate positive correlation between the cylindrical diopter of-0.75-0.00 DC group,-(1.00-1.50)DC group and-(1.75-3.00)DC group(r=0.43,r=0.42,r=0.64,all P=0.00).The overall coincidence rate of astigmatism axis with cycloplegia and noncycloplegia was 88.90%,the higher the cylindrical diopter,the higher the coincidence rate was,the difference was statistically significant(χ2=56.12,P=0.00).SureSight refractometer showed 18 eyes were+9.99 DS,42 eyes were-9.99 DC,the patients were all severe ametropia;when they were measured by retinoscopy with atropine cycloplegia.Conclusions The results of SureSight refractometer are correlated with those of retinoscopy with 1%atropine cycloplegia,for children with ametropia;the two methods have higher correlation.SureSight refractometer can be used for screening refractive status of large sample children in eye care work.
