Abstract Objective To study the efficacy of retrobulbar anesthesia in nonquantitative strabismus surgery. Methods A prospective, case-control study was performed on 85 patients who were presented for nonquantitative strabismus surgery. Retrobulbar anesthesia (61 eyes of 50 cases) and local infiltration anesthesia (40 eyes of 35 cases) was performed before operation respectively. Intraoperative and postoperative pain was assessed by using verbal rating scales, and anesthesia efficiency and operation efficiency were recorded. Data were analyzed with χ² test. Results Operation was well tolerated with no complication in patients with retrobulbar anesthesia. 54% patients showed no pain and 46% patients showed mild pain according to verbal rating scales, and this was significantly better than that of the control group (χ²=13.833, P<0.01). The success rate of surgery was 100%. Conclusion Retrobulbar anesthesia proves to be an efficient and safe procedure for nonquantitative strabismus surgery.
