脑视觉功能训练联合遮盖方案治疗儿童屈光不正性弱视的临床效果

Observation of Brain Visual Function Training and Occlusion Therapy in Clinical Treatment of Children Refractive Amblyopia

【目的】探讨脑视觉功能训练联合遮盖方案治疗儿童屈光不正性弱视的效果。【方法】本院收治的96例屈光不正性弱视患儿,根据信封法将患儿分为观察组和对照组。对照组采用遮盖疗法联合精细化训练治疗,观察组采用遮盖疗法联合脑视觉功能训练治疗。比较两组患儿治疗总有效率、立体视锐度SA≤60"情况、矫正视力、屈光度、调节幅度、调节灵活度及调节滞后量及不良反应发生情况。【结果】观察组治疗总有效率为90.74%(49/54),高于对照组患儿的69.64%(39/56)(P<0.05);治疗前,两组患儿立体视锐度SA≤60"的发生率比较,差异无统计学意义(P>0.05);治疗后,观察组立体视锐度SA≤60"的发生率为75.51%(37/49),高于对照组的38.30%(18/47)(P<0.05);治疗前,两组患儿矫正视力及屈光度比较,差异无统计学意义(P>0.05),治疗6个月后、治疗12个月后,两组矫正视力较治疗前升高,且观察组升高幅度大于对照组(P<0.05);治疗6个月后、治疗12个月后,两组屈光度较治疗前下降,且观察组降低幅度大于对照组(P<0.05);治疗前,两组调节幅度、调节灵活度及调节滞后量比较,差异无统计学意义(P>0.05),治疗后,两组患儿调节幅度及调节灵活度较治疗前升高,且观察组升高幅度大于对照组(P<0.05),两组患儿治疗后调节滞后量比治疗前下降,且观察组低于对照组(P<0.05);两组不良反应总发生率比较,差异无统计学意义(P>0.05)。【结论】脑视觉功能训练联合遮盖方案治疗儿童屈光不正性弱视,可显著提高患儿视力,有效改善患眼调节功能,且安全性高,值得临床推广使用。

【Objective】To observe the application effect of brain visual function training and occlusion therapy in the clinical treatment of children refractive amblyopia.【Methods】A total of 96 cases of children with refractive amblyopia admitted to our hospital were divided into two groups according to the random envelope method.In the control group,47 patients were treated with occlusion therapy combined with refine training,while 49 patients in the observation group were treated with occlusion therapy combined with brain visual function training.The total treatment effective rate,stereoscopic visual acuity(SA≤60"),corrected visual acuity,refraction,diopter,adjustment amplitude,adjustment flexibility,adjustment lag and the occurrence of adverse reactions were compared between the two groups.【Results】The total effective rate in the observation group was 90.74%(49/54),which was higher than that in the control group(69.64%,39/56)(P<0.05).Comparison of the incidence of SA≤60"in the two groups before treatment,the difference was not statistically significant(P>0.05).The incidence of stereoacuity SA≤60"in the posttreatment observation group 75.51%(37/49)was higher than that in the control group 38.30%(18/49)(P<0.05).The comparison of corrected visual acuity and refraction diopter in the two groups before treatment did not show statistical difference(P>0.05);However,the corrected visual acuities in two groups were higher after 6 months and 12 months treatment;And it was even higher in the observation group than in the control group(P<0.05).After 6 months and 12 months treatment,the refraction diopters in both groups decreased,and the reduction in the observation group was greater than that in the control group(P<0.05).In terms of the adjustment amplitude,adjustment flexibility and adjustment lag,there were no statistically significant differences between two groups before treatment(P>0.05).The amplitude and flexibility of children in the two groups increased after treatment.And children in the observation group showed better results compared to the control group(P<0.05).Meanwhile,the adjustment lag of the two groups decreased compared to before treatment;And the adjustment lag of the observation group was even lower than that of the control group(P<0.05).The overall incidence of adverse reactions in two group was no difference(P>0.05).【Conclusion】The occlusion therapy combined with brain visual function training refractive amblyopia treatment can significantly improve the vision of children,effectively improve the regulation function of the affected eye.It is very safe and is worth popularizing in clinical use.
