Prospective study of a single-injection peribulbar technique

Abstract

The single-injection peribulbar technique is an effective method of obtaining anesthesia and akinesia prior to anterior segment eye surgery. I conducted a prospective study of 2,684 consecutive cases of a particular peribulbar block that I performed for more than three years. The incidence of sight-threatening complications was 0.6%. None of the cases was canceled because of peribulbar hemorrhage. Only 1.2% of the cases required a supplemental injection of anesthesia.
