Effect of Partial Occlusion and Visual Perception Training on Visual Function Recovery in Children with Intermittent Exotropia after Surgery
Objective To investigate the effects of partial occlusion and visual perception training on visual function recovery in children with intermittent exotropia after surgery.Methods A total of 232 children with intermittent exotropia who received surgical treatment from September 2020 to August 2022 were randomly divided into control group(n=116)and observation group(n=116).The patients in the control group received visual perception training 7 days after operation,while the patients in the observation group received partial occlusion of one eye on the basis of the control group.The degree of strabismus,binocular visual function and quality of life were compared between the two groups.Results Three months after operation,the proportion of strabismus degree≤30° in the observation group was significantly higher than that in the control group(P<0.05),the recovery rate of binocular vision and fusion function and the number of macular fovea stereopsis in the observation group were significantly higher than those in the control group(P<0.05),the number of stereoscopic blindness cases was lower than that of the control group(P<0.05),and the scores of visual function and social psychology in the observation group were significantly higher than that of the control group(P<0.05).Conclusion Compared with the visual perception training,the combined treatment of partial occlusion of single eye can obviously improve the recovery of visual function and the quality of life of children after operation.
