摘　　要：目的探索学龄期外斜视儿童的视空间短时和工作记忆特征,为制定相关临床干预措施提供参考。方法采用病例对照研究法,于2017—2019年从中山大学中山眼科中心斜视弱视专科预约斜视矫正手术的患者中招募45名8~12岁外斜视学龄儿童和45名正常儿童,采用"方块敲击试验(tapping test)"评估儿童视空间短时记忆和视空间工作记忆。结果外斜视组与对照组儿童视空间短时记忆得分差异无统计学意义[(7.64±1.69)(8.00±1.66),t=-1.00,P=0.32];视空间工作记忆得分外斜视组儿童低于对照组儿童,差异有统计学意义[(5.98±1.23)(6.80±1.53),t=-2.81,P=0.01]。多元线性回归分析发现,在倒序敲击试验中,近立体视越好,得分越高(B=0.78,95%CI=0.23~1.33,P=0.01),恒定性外斜视儿童的得分高于间歇性外斜视(B=1.25,95%CI=0.16~2.34,P=0.03)。结论学龄期外斜视儿童视空间工作记忆受损,外斜视儿童的视空间工作记忆受近立体视和斜视恒定性的影响。Objective To explore the visuospatial memory characteristics of school-age children with exotropia and to analyze associated factors.Methods Based on a case-control study,45 exotropia children aged 8-12 years and 45 normal control children were recruited from 2017-2019.The " tapping test" was used to evaluate the visuospatial short-term and working memory of children.Results There was no significant differences in the scores of visuospatial short-term memory between the exotropia group and the control group [( 7.64±1.69)( 8.00±1.66),t =-1.00,P = 0.32 ].The scores of visuospatial working memory in the control group were higher than those in the exotropia group [( 5.98±1.23)( 6.80±1.53),t =-2.81,P = 0.01].In the reverse tapping test,the better the near stereopsis was,the higher the score was( B = 0.78,95% CI = 0.23-1.33,P = 0.01),and the constant exotropia children performed better than the intermittent exotropia children( B = 1.25,95%CI = 0.16-2.24,P = 0.03).Conclusion Visuospatial working memory is impaired in school-age children with exotropia,and the visuospatial working memory of exotropia children is affected by the near stereopsis and exotropia constancy.
