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。
Objective To evaluate the effect of antegrade retrograde migration of underdegree exotropia. Methods Twenty-two patients in the study group and 8 patients in the control group were included in this study. The near-oblique viewing angle was at least 15 PD. The study group included 22 external oblique rectus procedures and the control group received 8 standard external rectus muscles Migratory surgery. Results The study group 18/2 2 after surgery to see the near-out-slope ≤ 10PD, 2 2/2 2 to see the far-out slope ≤ 10PD, to see the far angle bevel average difference from preoperative 2 5 ± 8 11PD Reduce to postoperative 5 2 3 ± 4 0 3PD. The control group only 3/8 to see near the outside slope ≤ 10PD, 6/8 to see the far slope ≤ 10PD. Conclusions The results show that the effect of oblique posterior foraminotomy of exotropia with inferior collimator is better than that of standard external rectus muscle posterior retrusion.
