PURPOSE: To compare the effectiveness of sub-Tenon's versus peribulbar anesthesia in extracapsular @entity231 surgery. SETTING: Department of Ophthalmology and the Maccabi Eye Institute, @entity9604 Aviv, Israel. METHODS: Sixty-four consecutive @entity1 who had extracapsular @entity231 surgery were randomized to have sub-Tenon's or peribulbar anesthesia. Intraocular pressure (IOP) was measured before and 1 and 10 minutes after injection. The motility of the rectus muscles was evaluated before and 20 minutes after the injection, and the @entity1 's @entity148 level was recorded immediately after the injection. @entity158 was assessed intraoperatively and 1 and 24 hours postoperatively by @entity1 self-grading. RESULTS: One minute after the injection, IOP increased significantly in the peribulbar group (mean 7.97 mm Hg +/- 8.80 [SD]) (P < .05). There was no significant increase in the sub-Tenon's injection group (mean 0.12 +/- 3.09 mm Hg). In both groups, IOP returned to preinjection levels by 10 minutes postoperatively. @entity1 with peribulbar anesthesia reported a significantly higher level of @entity148 than those who had sub-Tenon's anesthesia (P < .05). Although the @entity158 levels were the same, the sub-Tenon's group reported significantly higher levels of @entity158 1 and 24 hours postoperatively; 16% in the sub-Tenon's group and none in the peribulbar group reported moderate @entity158 24 hours after anesthesia. Ocular motility was the same except for the inferior rectus muscle, which was less motile on average in the peribulbar group. CONCLUSION: Sub-Tenon's anesthesia led to less IOP elevation than peribulbar anesthesia and provided similarly good globe immobilization and approximately the same @entity158 levels intraoperatively.
