目的 :研究交替性内斜视的手术量。方法 :对 72例交替性内斜视采用相同检查方法 ,一组给同等量内直肌后徙术 ,另一组给不同量内直肌后徙术。结果 :在术后 1～ 6年的随访中 ,同等量后徙组保持正位(± 10 △) ,术后成功率为 89% ,非同等量后徙组手术成功率为 80 %。术后三级功能的建立 ,同等量后徙术显著优于非同等量后徙术。结论 :交替性内斜视手术采用同等量内直肌后徙术 ,不但手术成功率高 ,而且有利于手术后双眼三级功能的建立。
Objective: To study the amount of surgery for esotropia. Methods: 72 cases of alternative esotropia using the same examination method, one group to give the same amount of rectus muscle resettlement, the other group to different amount of rectus muscle resettlement. Results: In the follow-up of 1 to 6 years after operation, the same amount of posterior group maintained the positive position (± 10 △), the success rate was 89%. The success rate was 80% in the non-same group. After the establishment of three levels of function, the same amount of post-operative migration was significantly better than the same amount of post-operative migration. CONCLUSION: The same procedure of rectus abdominis replantation is used in alternative esotropia, which not only improves the success rate of operation, but also contributes to the establishment of tertiary function of both eyes after surgery.
