Sub-Tenon's anesthesia: an update

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.
