INTRODUCTION: Because of its complications, particularly globe perforation, retrobulbar injection has been progressively replaced by peribulbar anesthesia. However, with peribulbar anesthesia, the excessive rate of imperfect blockade requires supplemental injection. The authors have been performing local anesthesia by single caruncular sub-Tenon injection for many years. This technique is evaluated here. PATIENTS AND METHODS: A prospective study was carried out on 183 eyes. Regional anesthesia was given by a single caruncular sub-Tenon injection. In each case, the authors studied akinesia, analgesia, pain before, during, and after surgery, the number of supplemental injections, eyeball orientation, and surgical conditions. RESULTS: A total motor blockade was obtained in 157 cases (85.8%) and total lid akinesia in 176 (96.2%). Eight patients (4.4%) needed a second injection. During surgery, ten patients complained of pain (5.5%). The authors found that 27 eyes (14.7%) were divergent and 12 (6.5%) convergent. Surgical conditions were good or very good in 90% of cases. No complications due to the injection (perforation or lesion of the eyeball or the optic nerve) were noted. CONCLUSIONS: Single-injection caruncular sub-Tenon anesthesia is an alternative technique to classical peribulbar anesthesia. This technique is efficient, simple, easy to learn, reproducible, and seems to have a low rate of complications.LA: French
