BACKGROUND: To evaluate the safety and efficacy of sub-Tenon anesthesia for @entity1347 . METHODS: Thirty-two @entity1 diagnosed with @entity1713 were treated with @entity1347 under sub-Tenon anesthesia. After topical anesthesia, a buttonhole was made through the conjuntiva and Tenon's capsule 4 mm posterior to the limbus. Four milliliters of anesthetic solution was then delivered into the posterior sub-Tenon space using a blunt cannula. The buckling procedure was done immediately after the completion of anesthesia. We evaluated @entity910 and recorded the @entity158 with a visual analogue scale after surgery. RESULTS: There were no anesthesia related complications. Twenty-two @entity1 (69%) reported no @entity158 during surgery. Nine @entity1 (28%) felt @entity158 during surgery. However, the @entity158 was tolerable and the surgeries were finished smoothly with or without a supplemental anesthetic solution. One @entity1 (3%) experienced uncomfortable @entity158 and needed an additional retrobulbar block. Five @entity1 (16%) retained @entity1319 5 min after anesthesia, and only 4 @entity1 (13%) experienced total @entity910 . At the end of the surgery, 16 @entity1 (50%) had total @entity910 and 2 @entity1 (6%) retained @entity1319 . CONCLUSIONS: Sub-Tenon anesthesia is efficient and safe in @entity1347 . It can prevent the complications of peribulbar or retrobulbar anesthesia and is a good alternative to both methods of anesthesia, especially in highly myopic eyes.
