[Use of periocular and subfascial anesthesia in ophthalmic surgery].

The authors described the technique, usefulness and complications of 2 types of local anesthesia applied in patients who underwent ocular surgery. In 25 cases, peribulbar and in 136 sub-Tenon anesthesia were performed. Both methods were evaluated as efficacious. It was found that the simple and safer sub-Tenon anesthesia could replace retrobulbar blockade.
