Peribulbar anesthesia and sub-Tenon injection for vitreoretinal surgery: 300 cases.
We carried out a prospective study in order to evaluate the efficacy and safety of peribulbar anaesthesia supplemented by a sub-Tenon injection in case of inadequate analgesia during vitreoretinal surgery. ⋯ Our results demonstrate that peribulbar anaesthesia alone offers excellent analgesia in 85% of patients and supplemented by a sub-Tenon injection in 99%.
