摘要
目的:评价双眼外直肌超常量后徙联合缝线松弛治疗大度数间歇性外斜视的安全性及长期疗效。方法:回顾68例大度数间歇性外斜视患者,按遮盖24h后最大手术量设计,双眼外直肌后徙10～14mm包括放松缝线2～4mm。所有患者行详细相关检查。术后随访24mo到3a,分析近期和远期手术效果。结果:术后1wk:41例正位,斜视角为+8△～-8△;有14例轻度过矫。13例明显过矫,其中1例需要再手术。术后3mo,56例正位,斜视角为+8△～-8△;有6例轻度过矫,6例轻度欠矫;术后2～3a,56例正位,斜视度为+8△～-8△,有8例轻度欠矫。4例明显欠矫。眼球运动正常。结论:双眼外直肌超常量后徙联合缝线松弛治疗间歇性外斜视长期手术效果稳定,安全性高。
AIM：To evaluate the long-term results and security with the supernormal bilateral rectus muscle recession, including loose suture in large-angle intermittent exotropia. METHODS：We retrospectively analyzed the preand post-operative alignment of 68 patients with large-angle intermittent exotropia performed by supernormal bilateral rectus muscle recession including loose suture. The amount of recession was between 10-14mm, including loose suture for 2-4ram per lateral rectus muscle. The angle of exotropia was measured by the prism and cover test. The amount of surgery performed was based on the distance exotropic deviation after being occluded for 24 hours. All detailed ophthalmological examinations were made in every patient preoperatively and postoperatively. The follow-up period ranged from 24 to 36 months （average 27 months）. Long-term and short-term surgical outcomes were analyzed for all patients included in the study.RESULTS： After 1 week of post-operation of follow-up, 41 patients who underwent supernormal bilateral rectus muscle recession including loose suture, 64 patients were normtropia （-8^△≤deviation ≤8^△）, 14 patients were overcorreded lightly （8^△≤deviation ≤15^△）, 13 patients were overcorrected （15^△≤deviation ≤25^△ ）, 1 patient needed a re-operation. After 3 months of post-operation of follow-up, 56 patients who underwent supernormal bilateral rectus muscle recession including loose suture were normtropia （-8^△≤deviation ≤8^△）, 6patients were overcorrected lightly （8^△≤deviation ≤15^△）, 6 patients were undercorrected lightly （-15^△≤deviation ≤-8^△）. After average 27 months （between 24 months and 3 years） of post-operation of follow-up, 56 patients who underwent supernormal bilateral rectus muscle recession including loose suture were normtropia （-8^△≤ deviation ≤-8^△）.8 patients were undercorrected lightly （-8^△≤deviation ≤-15^△）, 4 patients were undercorrected obviously （-8^△≤deviation）. All patients had full ductions and versions postoperatively. CONCLUSION： Supernormal bilateral rectus muscle recession including loose suture in large-angle intermittent exotropia has good and stable long-term effeds and security.
