5~6岁儿童的立体视锐度及其相关因素研究

Stereoacuity and related factors in children aged 5 to 6 years

目的:探讨5~6岁儿童的立体视锐度分布及立体视锐度与眼球参数之间的关系。方法:于2017年招募南京市雨花台区5~6岁儿童进行相关检查,检查项目包括视力、眼位、眼球运动、眼前节、眼底、眼生物学参数、小瞳屈光度、睫状肌麻痹验光、随机点立体视等。分析5~6岁儿童立体视锐度分布情况,采用双变量相关分析及多元线性回归模型分析立体视锐度与眼球参数的关系。结果:共1154名儿童纳入研究,立体视锐度为40弧秒(652例)占56.5%,60弧秒(388例)占33.6%。多元线性回归结果显示,双眼眼轴差值(P<0.001)、生活视力(P<0.001)、双眼球镜度数差值(P<0.001)均与立体视锐度相关。结论:5~6岁儿童的双眼眼轴差值越大、生活视力越差、双眼球镜度数差值越大,则立体视越差。

Objective:To investigate the distribution of stereoacuity and the relationship between stereoacuity and ocular parameters in children aged 5 to 6 years.Methods:Children aged 5 to 6 years from Yuhuatai District,Nanjing City were recruited in 2017 for relevant examinations,including visual acuity(VA),ocular alignment and movements,anterior segment and fundus examination,refraction,axial length(AL),interpupillary distance,randot stereotest,etc.The distribution of stereoacuity in children aged 5 to 6 years was analyzed,and the relationship between stereoacuity and ocular parameters was analyzed by using bivariate correlation analysis and multiple linear regression model analysis.Results:A total of 1154 children were included in the study,with stereoacuity of 40 arc seconds(652 cases)accounting for 56.5%and 60 arc seconds(388 cases)for 33.6%.Multiple linear regression showed that interocular difference in AL(P<0.001),VA(P<0.001)and interocular difference in spherical refractive errors(P<0.001)were all correlated with stereoscopic vision.Conclusion:The children aged 5 to 6 years with higher interocular difference in AL,worse VA and higher interocular difference in spherical refractive errors have worse stereoacuity score.
