目的 评价改良式球周麻醉下行青光眼小梁切除术治疗青光眼的安全性和有效性。方法对418例596眼各类型青光眼采用改良式球周麻醉，行常规青光眼小梁切除术，观察麻醉效果及其并发症。结果 408例患者（574眼）麻醉满意，患者能配合顺利完成手术，术中、术后未出现严重并发症。术后矫正视力提高2行以上333眼，视力不变220眼，视力下降43眼。术后眼压在9～15mmHg（1kPa=7．5mmHg）者489眼，16～21mmhg者88眼，21～25mmHg者19眼。结论改良式球周麻醉行青光眼小梁切除术安全性高，麻醉效果好，麻醉并发症少，是一种值得推广的麻醉方法。
Objective To evaluate the efficacy and safety of the modified peribulbar anesthesia in trabeculectomy of glaucoma. Methods Five hundred and ninety-six eyes of 418 cases of glaucoma patients received the operation of trabeculectomy under the modified peribulbar anesthesia. Both the efficacy of the anesthesia and intraoperative or postoperative complications were evaluated. Results Four hundred and eight patients （574 eyes） cooperated well during the operation. No serious intraoperative or postoperative complications were observed. Three hundred and thirty-three eyes got an improved corrected vision of 2 rows more than the preoperative one. While 220 eyes＇ corrected vision got no improved and 43 eyes＇ dropped. The IOPs of 489 eyes, 88 eyes and 19 eyes were controlled in the ranges of 9-15 mmHg（1 kPa=7.5 mmHg）, 16-21 mmHg and 21-25 mmHg respectively. Conclusion The modified peribulbar anesthesia is safe and effective for the trabeculectomy of glaucoma and is appropriate for more applications.
