摘　　要：间歇性外斜视是儿童眼科的常见疾病之一,也是目前眼科学研究的热点领域之一.本研究使用多物体跟踪实验范式,系统考察了间歇性外斜视儿童,相对于弱视儿童以及正常对照儿童,注意的容量是否存在异常.实验结果发现间歇性外斜视儿童和弱视儿童的注意跟踪能力都显著地差于正常对照儿童,而且间歇性外斜视儿童和弱视儿童的跟踪成绩基本没有差别,他们的注意跟踪功能的受损程度相近.本研究首次报道了间歇性外斜视儿童注意能力的行为异常,对进一步研究间歇性外斜视的发病机理和早期临床诊断具有潜在的参考意义.Intermittent exotropia is a common pediatric ocular disease, which is also a hot research area in ophthalmology. In this study, we tested the tracking ability of children with intermittent exotropia using multiple object tracking （MOT） paradigm, and compared with amblyopic children and normal children. The experimental results showed that the tracking capacity of children whether with intermittent exotropia or amblyopia was significantly decreased as compared with normal children, and children with intermittent exotropia suffers the same degree of damage with children with amblyopia. It is the first report of the abnormal attentive ability of children with intermittent exotropia, which may be beneficial to future research of pathogenesis and early diagnosis of the disease.
