目的观察分析不同发病年龄非调节性内斜视患者手术前后双眼单视功能的变化。方法将40例非调节性内斜视患者按照不同的发病年龄分为4组。用同视机测定双眼单视功能,用《颜少明立体视觉检查图》测定看近立体视锐度。分析比较不同发病年龄的患者手术前后的远双眼单视功能及近立体视锐度的变化。结果不同发病年龄患者术后获得立体视的情况不同,各组间差异有统计学意义(P<0．05)。结论非调节性内斜视发病年龄越小,术后获得立体视的可能性越小。
Objective To observe the changes of binocular vision function in patients with non-accommodative esotropia at different ages of onset. Methods 40 cases of non-accommodative esotropia were divided into 4 groups according to different age of onset. With the same set of eyes binocular vision function, with “Yan Shaoming stereoscopic visual map” to see near stereoacuity. Analysis of patients with different ages of onset before and after surgery far binocular vision and near stereoacuity changes. Results The patients with different ages of onset had different stereopsis after operation, and there was significant difference among the groups (P <0.05). Conclusion The smaller the age of onset of non-accommodative esotropia, the less likely it is to obtain stereopsis after surgery.
