学龄期外斜视儿童快速命名特征分析

Rapid automatized naming characteristics of school-age exotropia children

目的比较学龄期外斜视儿童与正常儿童在快速命名任务中的表现并分析外斜视相关临床指标对快速命名的影响,为相关领域的研究提供参考。方法依《斜视分类专家共识(2015年)》诊断标准,从中山大学附属眼科中心招募45名外斜视儿童为病例组,同时期在社区招募视力正常儿童,按年龄、性别、父母文化水平进行成组匹配,最终纳入45名儿童为对照组。对其进行外斜视相关临床指标的检测,并采用经典的快速命名任务对两组被试进行快速命名能力的评估。结果外斜视组儿童字母快速命名时间长于对照组[(26.87±10.18)(21.98±7.29) s],差异有统计学意义(t=2.73,P=0.01);外斜视各项临床指标中的斜视度、症状时长、AC/A值、疾病分类、同时视、近立体视、远立体视与字母快速命名得分相关无统计学意义(r值分别为-0.16,0.23,0.20,0.06,0.09,0.05,0.20,P值均>0.05)。结论学龄期外斜视儿童存在快速命名缺陷,且与临床指标无显著相关。

Objective To understand the characteristics of rapid naming in exotropia children,and to analyze the influence of clinical indicators related to exotropia on the rapid naming.Methods A total of 45 exotropia children were recruited according to the diagnostic criteria of consensus of strabismus classification experts( 2015) from the Zhongshan ophthalmic center as the case group,and 45 children of the same age,gender and parental educational status were recruited as the control group without any ocular diseases.All children were evaluated the ability of the rapid naming by classical rapid naming test.Results The letter rapid naming time of children with exotropia was longer than that in control group [( 26.87±10.18)( 21.98±7.29) s],and the difference was statistically significant( t = 2.73,P = 0.01),however there was no significant correlation between strabismus degree,symptom duration,AC/A ratio,disease classification,simultaneous vision,the near stereopsis,the far stereopsis and the letter rapid naming in the clinical indicators of exotropia( r =-0.16,0.23,0.20,0.06,0.09,0.05,0.20,P>0.05).Conclusion Rapid naming might be impaired among children with exotropia,with no significant correlation between this defect and its clinical indicators.
