Limited data exist on the recovery of ocular motility after adjustable suture strabismus surgery performed under local anesthesia. The timing of adjustment has been chosen empirically and has varied widely. We sought to more precisely quantify the recovery of motility by measuring ductions before and after surgery with a modified arc perimeter. Twenty-one eyes of 20 patients were studied. All patients underwent adjustable suture strabismus surgery under retrobulbar or peribulbar anesthesia using 2% lidocaine with hyaluronidase. Mean ductions orthogonal to the field of action of the operated muscle(s) returned to 90% of preoperative levels between 5 and 6 hours after injection. We recommend adjustment 6 or more hours after injection, or at least 5 to 6 hours postoperatively, when 2% lidocaine with hyaluronidase is used for local anesthesia.
关于局部麻醉下可调节缝线斜视手术术后眼球运动恢复的资料有限。调整时间一直是凭经验选择的，且差异很大。我们试图通过使用改良弧形视野计测量手术前后的眼外肌运动，来更精确地量化运动恢复情况。对20例患者的21只眼进行了研究。所有患者均在球后或球周麻醉下，使用含透明质酸酶的2%利多卡因进行可调节缝线斜视手术。与手术肌肉作用方向垂直的平均眼外肌运动在注射后5至6小时恢复到术前水平的90%。我们建议，当使用含透明质酸酶的2%利多卡因进行局部麻醉时，在注射后6小时或更长时间，或术后至少5至6小时进行调整。
