目的探讨不同年龄组共同性外斜视术后眼位变化,双眼单视功能重建及欠矫的相关因素。方法对163例不同年龄组的共同性外斜视患者术前术后行眼位及双眼单视功能测定,进行临床分析。结果3-7岁组45例,术后眼位稳定,双眼单视功能重建,欠矫3例;8-12岁组52例,眼位较稳定,双眼单视功能重建,但融合范围小,术后欠矫6例;≥13岁组66例,术后欠矫15例,双眼单视功能部分恢复。结论手术治疗是共同性外斜视的最佳选择,且年龄越小效果越好,术后双眼单视功能重建对眼位的稳定影响甚大;大龄组手术矫正眼位后,双眼单视功能重建和完善较困难,术后欠矫是普遍存在的,术中如无复视,保持适度过矫,可降低远期欠矫的发生。
Objective To explore the relationship between ocular position changes, binocular single vision function reconstruction and undercorrection after common exotropia in different age groups. Methods 163 cases of common exotropia in different age groups underwent preoperative and postoperative ocular and binocular single vision function analysis for clinical analysis. Results 45 cases of 3-7 years old group had stable ophthalmopathy, reconstruction of binocular single vision function and three cases of undercorrection. In the group of 8-12 years old, 52 cases had stable ophthalmic position and reconstruction of binocular monovision. However, the fusion range was small, Six patients had undercorrection after operation, 66 patients ≥13 years of age, and 15 patients undercorrected after operation. Monocular visual function was partially recovered in both eyes. Conclusions Surgical treatment is the best choice for common exotropia, and the younger the effect is, the better postoperative binocular single vision reconstruction has a great effect on the stability of the ocular position. In the older age group, Improve the more difficult, less postoperative correction is ubiquitous, intraoperative without diplopia, to maintain a moderate overcorrection, can reduce the occurrence of long-term undercorrection.
