Application of modified peribulbar anesthesia in trabeculectomy

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.
