Comparative Study
[Evaluation of single-injection caruncular sub-Tenon's anesthesia].
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. We have been performing local anesthesia using caruncular sub-Tenon single injection for many years. This technique is evaluated. ⋯ 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.
