Abstract：Objective To investigate the effects of multimedia visual function training on visual function recon-struction and perceptual eye position in postoperative patients with intermittent exotropia.Methods A total of 80 patients who underwent surgical treatment for intermittent exotropia between July 2021 and June 2022 were enrolled.The patients were randomly assigned to a control group(40 patients)and an observation group(40 patients)using a random number table method.All patients underwent surgical treatment for intermittent exotropia.The control group did not receive binoc-ular visual function training postoperatively,while the observation group received multimedia visual function training.Both groups were followed up for 3 months after surgery.Visual function,Titmus near stereopsis,perceptual eye position,and strabismus degree were compared before and 3 months after surgery.Results Compared to preoperative measurements,at 3 months postoperative,the proportions of patients with strabismus ≤10°,simultaneous vision,visual fusion,and stere-opsis increased in both groups,with higher proportions in the observation group compared to the control group.The pro-portions of patients with strabismus＞10° and ≤20°,horizontal deviation(pixels),and vertical deviation(pixels)de-creased,with lower values in the observation group compared to the control group.At 3 months postoperative,the propor-tion of patients with macular stereopsis and macular foveal stereopsis increased in the observation group,and these were higher than those in the control group.The proportion of patients without stereopsis decreased and was lower in the obser-vation group compared to the control group.The proportion of patients with orthotropia was higher and those with undercor-rection was lower in the observation group compared to the control group(P＜0.05).Conclusion Multimedia visual function training effectively reduces the degree of strabismus in postoperative intermittent exotropia patients,increases the rate of orthotropia,and significantly improves postoperative binocular visual function,Titmus near stereopsis,and percep-tual eye position.
