目的探讨大角度外斜视行外直肌悬吊后徙术与外直肌超常量后徙术的比较,观察手术效果。方法两组病例共42例,手术前后均采用角膜映光法、三棱镜遮盖试验测定眼位。一组实施外直肌悬吊后徙术,另一组则行外直肌超常量后徙术。结果两组术前斜视角大小无显著性差异。术后眼位:外直肌悬吊后徙组≤±10~Δ18例,正位率85.71%;外直肌超常量后徙组≤±10~Δ19例,正位率90.48%,两组正位率比较差异无显著性。结论采用外直肌悬吊后徙术矫正大角度外斜视,既可以达到外直肌超常量后徙术的效果,又降低了巩膜意外损伤的危险,具有合理、实用、安全、简便等特点。 Objective To investigate the comparison of retrograde rectus abdominis replantation with rectus abdominis rectus after large angle exotropia and observe the effect of surgery. Methods A total of 42 cases of two groups of patients, before and after surgery were used corneal mapping, prism cover test to determine the eye position. A group of postoperative rectus abdominis migration surgery, while the other group is outside the rectus abdominoma resettlement surgery. Results There was no significant difference between the two groups in preoperative squint angle. Postoperative ocular: posterior rectus femoris group ≤ ≤ 10 ~ Δ18 cases, the positive rate was 85.71%; exoskeleton hypervariability posterior group ≤ ± 10 ~ Δ19 cases, the positive rate of 90.48%, the two groups were positive No significant difference in bit rate. Conclusions It is reasonable, practical, safe and easy to correct the large-angle exotropia with the rectus abdominis rectocele after rectus ablation. It can not only achieve the effect of extrinsic posterior extremity reimplantation but also reduce the risk of scleral accidental injury.
