间断遮盖法联合视知觉学习治疗儿童弱视的疗效观察

Effect of Intermittent Occlusion Combined with Visual Perceptual Learning on Amblyopia in Children

【目的】探讨间断遮盖法联合视知觉学习治疗儿童弱视的临床疗效.【方法】选择本院2016年1月至2018年1月诊治的80例弱视患儿,采用随机数表法分为观察组和对照组,每组40例.对照组采用间断遮盖法治疗,观察组在对照组基础上加用视知觉学习治疗.比较两组治疗前及治疗后3个月、6个月、12个月后视觉改善情况.【结果】观察组基本治愈率优于对照组,差异具有统计学意义(P<0.05);两组治疗前和治疗3个月最佳矫正视力(BCVA)比较差异无统计学意义(P>0.05),治疗6个月、12个月观察组BCVA优于对照组,其差异具有统计学意义(P<0.05);观察组治疗3~6个月期间最佳矫正视力平均提高(1.00±0.40)行,优于对照组的(0.70±0.30)行,其差异具有统计学意义(P<0.05);治疗后两组Titmus立体视均提高,观察组Titmus立体视恢复≤60″人数比例优于对照组,组间差异具有统计学意义(P<0.05).【结论】间断遮盖法联合视知觉学习可改善弱视患儿矫正视力,提高治愈率,疗效显著,值得临床推广应用.

【Objective】To explore the clinical effect of intermittent occlusion combined with visual perceptual learning on amblyopia in children.【Methods】Eighty cases of amblyopia in our hospital from January 2016 to January 2018 were randomly divided into observation group and control group,40 cases in each group.The control group was treated with intermittent occlusion,and the observation group was treated with visual perception learning on the basis of the control group.The visual improvement of the two groups before treatment and after 3 months,6 months,12 mon ths were compared.【Results】The basic cure rate of the observati on group was better than that of the control group,the difference was statistically significant(P<0.05);there was no statistically significant difference in BCVA between the two groups before and 3 months after treatment(P>0.05),and the BCVA of the observation group was better than that of the control group at 6 and 12 months after treatment,the difference was statistically significant(P<0.05);the best corrected visual acuity of the observation group increased by(1.00±0.40)lines on average during 3-6 months of treatment,which was better than that of the control group(0.70±0.30).The difference was statistically significant(P<0.05);after treatment,the stereopsis of both groups was improved.The proportion of people whose stereopsis recovery≤60" in the observation group was better than that in the control group,and the difference between the two groups was statistically significant(P<0.05).【Conclusion】 Intermit te nt occlusion combined with visual perceptual learning can improve the corrected visual acuity of children with amblyopia and improve the cure rate.It is worthy of clinical application.
