METHODS: A total of 94 children with intermittent exotropia diagnosed in our hospital from August 2016 to January 2019 were selected and 94 eyes were affected. According to whether the postoperative visual training was divided into two groups, 47 patients(47 affected eyes)were not visually trained after operation and were included in the control group; 47 patients(47 affected eyes)were visually trained 2wk after operation and were included in the observation group. Follow-up for 6mo was performed to observe the recovery of visual function and eye position regression.

RESULTS: Six months after surgery, the proportion of children in the observation group with simultaneous visual function(89%), fusion function(85%)and stereoscopic function(40%)was significantly higher than that in the control group(53%, 47%, 19%), and the orthotopic rate of children in the observation group was significantly higher than that in the control group(91% vs 66%).

CONCLUSION: The binocular visual function training after intermittent exotropia in children can promote the recovery of binocular visual function and reduce the risk of postoperative eye position regression.
