摘要
目的:比较间歇性外斜视(IXT)患者与眼位正常儿童在双眼视功能、发生阅读学习障碍方面的差异并分析其相关性。方法:前瞻性临床研究。采用随机数字抽样法收集2021年7月至2022年3月在广州市妇女儿童医疗中心眼科门诊就诊的IXT儿童(39例,作为IXT组)和眼位正常儿童(44例,作为对照组)。检查并记录2组性别、年龄、最佳矫正视力(BCVA)、等效球镜度(SE)、远近水平眼位、集合近点、近立体视、调节幅度、单双眼调节灵活度,完成《儿童汉语阅读障碍量表》和《儿童学习障碍筛查量表》。使用独立样本t检验、非参数检验法差异性检验(曼-惠特尼法)、卡方检验、K-W检验、Spearman相关系数对数据进行统计分析。结果:IXT组与对照组性别、年龄、BCVA、SE比较差异无统计学意义(均P>0.05)。2组儿童远近眼位、近立体视、集合近点、双眼调节灵活度差异均有统计学意义(均P<0.001)。调节幅度和单眼调节灵活度在2组中差异无统计学意义(P>0.05)。IXT组的年龄组间各指标差异无统计学意义(P>0.05)。IXT组和对照组在阅读障碍发生率和学习障碍评分方面差异有统计学意义(χ^(2)=8.45,P=0.004;t=-4.07;P<0.001)。阅读障碍与远近水平眼位、近立体视、集合近点、双眼Flipper检查结果和学习障碍评分显著相关(r=-0.43、-0.37、-0.57、0.41、-0.54、-0.62,均P<0.05)。结论:IXT患儿与眼位正常儿童相比,存在部分双眼视觉功能异常,容易出现阅读困难及学习障碍。
Objective:To determine the differences and correlations of binocular visual function,reading dyslexia and learning disorder between intermittent exotropia(IXT)patients and orthophoric children.Methods:In this prospective clinical study,39 IXT children(IXT group)and 44 orthophoric children(control group)were sampled by random number method among children who visited the ophthalmology clinic of Guangzhou Women and Children's Medical Center from July 2021 to March 2022.Gender,age,best corrected visual acuity(BCVA),spherical equivalent(SE),horizontal squint,near point of convergence,near stereopsis,amplitude of accommodation,monocular and binocular Flliper test of the two groups were checked and recorded.The participants had completed the Dyslexia Checklist for Chinese Children(DCCC)and The Pupil Rating Scale Revised Screening for Learning Disabilities(PRS).Independent sample t-test,Mann-Whitney U test,Chi-square test,Kruskal-Wallis test,Spearman correlation analysis were used to statistically analyze the data.Results:There were no significant difference in gender,age,BCVA and SE between the two groups(P>0.05).There were statistically significant differences in horizontal squint,near stereopsis,near point of convergence,and binocular Flliper test between the two groups(P<0.001).There was no significant difference in the amplitude of accommodation and the monocular Flliper test between the two groups(P>0.05).There was no difference in all indicators between age groups of IXT group(P>0.05).There were significant differences in the incidence of dyslexia and the grade of PRS(χ^(2)=8.45,P=0.004;t=-4.07,P<0.001).The occurrence of the dyslexia was significantly correlated with the results of horizontal squint,near stereopsis,near point of convergence,binocular Flipper test and PRS grade(r=-0.43,-0.37,-0.57,0.41,-0.54,-0.62,respectively,all P<0.05).Conclusions:Compared with orthophoric children,patients with IXT have partial abnormal binocular vision function,and are prone to get reading dyslexia and learning disorder.
