In the last decade, anesthesiologists have become increasingly involved in administering regional eye blocks, while providing care for patients undergoing ophthalmic surgery. This article describes the two major approaches to regional eye block, namely retrobulbar and peribulbar, with special consideration given to relevant orbital anatomy and technical guidelines. Potential complications, ocular and systemic, with their risk factors, are reviewed. Anesthesiologists wishing to acquire skill in administering safe regional blockade are encouraged to familiarize themselves with regional anatomy and specific guidelines suggested herein.
