儿童间歇性外斜视手术前后双眼视功能的临床研究

Clinical study on preoperative and postoperative binocular visual function of children with intermittent exotropia

目的观察儿童间歇性外斜视手术后双眼视功能的恢复情况。方法选取168例间歇性外斜视患儿,行斜视矫正手术。手术前后应用同视机检测I级视功能和Ⅱ级视功能,用Titmus立体视觉检查图观察Ⅲ级视功能,并对数据进行统计学分析。结果 168例患儿中,术前Ⅰ级视功能82例,术后增加到130例,手术前后比较差异有统计学意义(P<0.05);术前Ⅱ级视功能54例,术后增加至130例,差异有统计学意义(P<0.05);Titmus立体视觉检查图发现,术前远立体视19例,术后增加至71例,82例患者术前有不同程度的近立体视,术后增加至136例,差异均有统计学意义(P<0.05,P<0.01)。结论手术治疗有助于间歇性外斜视患儿双眼视功能的重建。

Objective To investigate the recovery of postoperative binocular visual function of children with intermittent exotropia. Methods A total of 168 children with intermittent exotropia were taken corrective procedures to correct strabismus. Synoptophore was used to detect visual function at I stage and at II stage. Titmus stereogram was used to detect visual function at III stage. All data were statistically analyzed. Results In 168 children with intermittent exotropia,There were 82 children with visual function at I stage preoperatively, and 130 children postoperatively, there was statistical difference（P 〈0.05）. There were 54 children with visual function at II stage preoperatively,and 130 children postoperatively, there was statistical difference （P 〈 0.05 ）. Titmus stereogram showed that there were 19 cases with distant stereopsis preoperatively and 71 children postoperatively, 82 children with near stereopsis preoperatively and 136 children postoperatively, there were statistical differences （P 〈 0. 05,P 〈 0. 01 ）. Conclusion Operation is good for reconstruction of binocular visual function for children with intermittent exotropia.
