Analysis of the children's dynamic and static stereopsis of intermittent exotropia

Abstract

AIM: To compare and analyze the stereopsis of intermittent exotropia children under the different backgrounds of dynamic stimuli and static stimuli.METHODS: We collected 56 children(male 26, female 30 with intermittent exotropia at the age from 5y to 12y and examined their stereopsis under the different backgrounds of dynamic stimuli and static stimuli using a multidimensional sense perception training software. The differences between the dynamic stereopsis and static stereopsis were compared.RESULTS: Totally 17 cases(30%)had both dynamicstereopsis and static stereopsis, 39 cases(70%)had either dynamic or static stereopsis deficit, only 10 cases(26%)had dynamic stereopsis, 25 cases(64%)static stereopsis left and 4 cases(10%)were without any form of stereopsis. The positive rate of dynamic stereopsis was better than the positive rate of static stereopsis, with statistical significance(PCONCLUSION: Dynamicstereopsis is better than the static stereopsis to intermittent exotropia children.
