Value of strabismus correction combined with visual training in the treatment of intermittent exotropia and its effect on multifocal visual evoked potential

目的探讨斜视矫正术联合视觉训练治疗间歇性外斜视的临床价值及对多焦视觉诱发电位的影响。方法收集邯郸市眼科医院2019年1月~2022年1月收治的间歇性外斜视患儿80例,按抽签法分为观察组和对照组,每组各40例。对照组给予斜视矫正术治疗,观察组给予斜视矫正术联合视觉训练治疗,比较两组治疗后视觉感知不适症状发生率,比较两组治疗前后斜视度数(视近度、视远度、平均斜视度)、融合范围、生存质量、多焦视觉诱发电位变化。结果治疗后两组视近度、视远度、平均斜视度均明显较治疗前下降,且观察组视近度、视远度、平均斜视度明显低于对照组(P<0.05);治疗后观察组患儿融合范围明显高于治疗前及对照组治疗后(P<0.05);治疗后观察组患儿社会心理、视觉功能评分明显高于治疗前及对照组治疗后(P<0.05);观察组治疗后视觉感知不适症状总发生率明显低于对照组(P<0.05);治疗后观察组第1环潜伏期、第2环潜伏期明显低于治疗前及对照组治疗后(P<0.05)。结论斜视矫正术联合视觉训练用于间歇性外斜视患儿治疗后,能明显改善斜视度,增加其融合范围,提高生存质量,减少患儿视觉感知不适症状发生率,改善多焦视觉诱发电位。

Objective To explore the clinical value of strabismus correction combined with visual training in the treatment of intermittent exotropia and its influence on multifocal visual evoked potential.Methods Eighty children with intermittent exotropia admitted to Handan Eye Hospital from January 2019 to January 2022 were divided into observation group and control group by lot drawing,with 40 cases in each group.The control group was treated with strabismus correction,and the observation group was treated with strabismus correction combined with visual training.The incidence of visual perception discomfort after treatment was compared between the two groups,and the number of strabismus degrees(nearsightedness,farsightedness,average strabismus),fusion range,quality of life,and multifocal visual evoked potential changes before and after treatment were compared between the two groups.Results After treatment,the near,far and average strabismus of the two groups were significantly lower than those before treatment,and the near,far and average strabismus of the observation group were significantly lower than those of the control group(P<0.05);After treatment,the fusion range of children in the observation group was significantly higher than before treatment and after treatment in the control group(P<0.05);After treatment,the scores of children’s social psychology and visual function in the observation group were significantly higher than those before treatment and after treatment in the control group(P<0.05);The incidence of visual perception discomfort in the observation group after treatment was significantly lower than that in the control group(P<0.05);After treatment,the latency of the first loop and the second loop in the observation group were significantly lower than those before treatment and after treatment in the control group(P<0.05).Conclusion The strabismus correction combined with visual training can significantly improve the strabismus degree,increase the fusion range,improve the quality of life,reduce the incidence of visual perception discomfort,and improve the multifocal visual evoked potential in children with intermittent exotropia.
