AIM: To investigate postoperative binocular visual function reconstruction in intermittent exotropia children with binocular visual training.

METHODS: The clinical data of 108 cases of intermittent exotropia children admitted to our hospital from April 2013 to April 2016 were retrospectively analyzed. Among them, 45 cases with binocular visual function training were included in the control group; the other 63 cases with TSJ-IV synoptophore training software for binocular vision training were included in the observation group. The binocular visual function reconstruction and eye position regression of the two groups were observed.

RESULTS: Baseline data of binocular visual function and strabismus in two groups had no significant difference before surgery(P>0.05). At 3mo after operation, the visual function of grade three in the observation group was significantly improved, and the proportion of simultaneous vision, visual fusion and stereopsis in the observation group were significantly higher than those in the control group(P<0.05). The proportion of patients with macular stereopsis and foveal stereopsis in the observation group was significantly higher than that in the control group, and the proportion of patients without stereopsis in the observation group was significantly lower than that in the control group, and the difference was statistically significant between groups(P<0.05). At 3mo after operation, the proportion of strabismus ≤30^△ in the observation group was significantly higher than that in the control group, with statistical significance(P<0.05). In addition, the eye position regression rate of the observation group was significantly lower than that of the control group in the postoperative 1a follow-up, and there was significant difference between the two groups(P<0.05).

CONCLUSION: The children with intermittent exotropia taking postoperative synoptophore training can promote binocular visual function reconstruction, ameliorate the degree of strabismus, and avoid postoperative eye recession.
