Sub-Tenon's Infusion of Local Anesthetic for Strabismus Surgery

Abstract

We used a blunt irrigating cannula to infuse tetracaine 0.5% solution into the posterior sub-Tenon's space in 26 consecutive patients undergoing strabismus surgery under local anesthesia. All patients were sedated with combinations of fentanyl citrate and either propofol or midazolam. The results suggest that this technique is a safe and effective method of performing strabismus surgery under local anesthesia.
