双眼视功能训练对间歇性外斜视患者术后双眼视功能重建的影响

Effect of binocular visual function training on the reconstruction of binocular visual function in postoperative patients with intermittent exotropia

目的:探讨双眼视功能训练对间歇性外斜视患者术后双眼视功能重建及维持术后眼位稳定的作用。方法:收集2010-01/2015-12在我院行斜视手术的资料完整的间歇性外斜视患者142例,按术后是否进行双眼视功能训练分为治疗组(术后采用DV-100诊疗系统的三级视功能训练光盘针对双眼情况行同时视、融合功能及立体视功能光盘训练)和对照组(术后未行干预治疗)。分析两组患者术前、术后1、3、6mo,1a的斜视度数和双眼视功能情况,比较两组患者双眼视功能和眼位情况的差异。结果:术后6mo,1a,治疗组的眼位情况好于对照组,差异均有统计学意义(P<0.05)。术后1、3、6mo,1a,治疗组的三级视功能均显著优于对照组,差异均有统计学意义(P<0.05)。结论:间歇性外斜视患者通过手术获得眼位正位后,其双眼视功能可有一定程度恢复。术后通过视知觉学习,行双眼视功能训练,可以更快、更好地促进患者双眼视觉的恢复和重建,从而获得立体视觉,可以更好地稳定眼位,有利于减少术后眼位回退。

·AIM:To explore the effect of binocular visual function training on the reconstruction of binocular visual function and maintaining the stable eye position in postoperative patients with intermittent exotropia.·METHODS:A total of 142 patients with intermittent exotropia underwent strabismus surgery in our hospital from January 2010 to December 2015 were enrolled.These patients were divided into two groups according to whether had binocular visual function training after surgery.The treatment group was used the DV-100 system to train the three-level visual function after surgery.For the control group,no intervention was performed after the operation.Respectively analysis the differences of binocular visual function and eye position in the two groups of patients before and 1mo after surgery,3mo after surgery,6mo after surgery,and 1a after·RESULTS:The rate of the positive eye position in the treatment group was higher than the control group in the 6mo and 1a after surgery,and statistically significant difference was found(P<0.05).In 1,3,6mo and 1a after surgery,there were statistically significant differences in binocular visual function between the two groups.The recovery of binocular visual function in the treatment group was significantly better than that in the control group.·CONCLUSION:The binocular visual function may have a certain degree of recovery in the patients with intermittent exotropia after surgery to obtain positive eye position.Through the postoperative visual perception learning and binocular visual function training,the binocular visual function can be better and faster recovered and reconstructed so as to obtain stereoscopic vision.It can better stabilize the eye position and help to reduce the rate of the patient’s eye position fallback after surgery.
