Injection of corticosteroids into the posterior subtenon space is a well established and highly effective modality in the treatment of intermediate uveitis. The conventional technique of posterior subtenon injection involves the use of a sharp tipped 26‐gauge, 5/8 inch needle that must be inserted up to its hub to obtain adequate placement of the drug into the posterior subtenon space. With this technique the risk of perforation of the globe, although minimal, remains a potential complication. Herein is described a new technique for injection of corticosteroids into the posterior subtenon space using an intravenous cannula made of polytetrafluoroethylene (PFTE) that allows safer delivery of the drug into the posterior subtenon space.
