Abstract: Sub-Tenon's block has become the most common technique of orbital regional anesthesia in many centers. It provides effective anesthesia to the orbit with a lower incidence of sight-threatening complications than sharp needle techniques. This article will discuss the relevant anatomy, finer points of sub-Tenon's block technique, and the evidence supporting its safety.

Keywords: anesthesia local, anesthesia ophthalmic, sub-Tenon's block, techniques, complications
