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.
