【摘要】 目的 评价集合不足型外斜视外直肌斜向后徙的效果。方法 研究组 2 2例 ,对照组 8例 ,看近斜视角大于看远斜视角至少 15PD ,研究组 2 2例行外直肌斜向后徙术 ,对照组 8例行标准的外直肌后徙术。结果 研究组 18/2 2术后看近外斜度≤ 10PD ,2 2 /2 2术后看远外斜度≤ 10PD ,看近看远外斜角平均差值由术前 2 5± 8 11PD减少到术后 5 2 3± 4 0 3PD。对照组仅 3 /8术后看近外斜度≤10PD ,6/8术后看远外斜度≤ 10PD。结论 集合不足型外斜视外直肌斜向后徙术效果优于标准的外直肌后徙术。

【Abstract】 Objective To evaluate the efficacy of slanted recession of the lateral rectus(LR) muscle for exotropia(XT)with convergence weakness.Methods 22 study patients and 8 control subjects with XT greater at near than at distance by≥15 prism diopters(PD),22 patients underwent slanted LR recession,and 8 control subjects underwent standard LR recession.Results Slanted LR recession reduced the XT to≤10PD in all patients at distance and in 18/22 patients at near.Additionally,the mean difference between the distance and near exodeviation was reduced from 25±8.11PD preoperatively to 5.23±4.03PD postoperatively.6/8 in the control group demonstrated postoperative deviations of ≤10PD at distance,but 3/8 had residual exodeviations ≥10PD at near.Conclusions Slanted recession of the LR is superior to standard recession in reducing both distance and near XT and in collapsing the difference between them.
