目的 探讨视网膜脱离手术后斜视的手术特点和效果。方法 2 3例 2 6眼视网膜脱离手术后斜视 ,手术前后三棱镜加交替遮盖或三棱镜映光法 (Krimsky法 )测定客观斜视角等 ,术后追踪 2～ 2 8月。结果 (1)术中特点 :眼外肌粘连、纤维化的程度不同 ;各直肌附着点距离角膜缘比正常的平均远 2～ 3mm。 (2 )斜视矫正量 :以单纯直肌减弱术矫正量最小 ,直肌减弱联合缩短再复位术矫正量最大。 (3)术后眼位 :第 1正位率 5 6 5 % ,改善率 43 5 %。结论 解除牵制因素联合直肌手术能有效的解除、改善这种特殊的斜视和复视。
Objective To investigate the surgical characteristics and effects of strabismus after retinal detachment surgery. Methods Twenty-three cases of strabismus after retinal detachment surgery were treated with retrograde prisms and Krimsky’s method (Krimsky method) before and after the operation. The postoperative follow-up was performed from February to August. Results (1) intraoperative characteristics: extraocular muscle adhesion, fibrosis different degrees; the rectus abdominis attachment point from the normal than the average distance of 2 ~ 3mm. (2) The amount of strabismus correction: a straight rectus muscle weakening the least amount of correction, rectus abdominis reduction and re-reduction surgery the largest amount of correction. (3) Postoperative ophthalmic position: The first orthosis rate was 56.5% and the improvement rate was 43.5%. Conclusion Relieving the co-factors of rectus surgery can effectively relieve and improve this special strabismus and diplopia.
