Abstract
Posterior peribulbar anesthesia is a safe alternative to retrobulbar anesthesia for ophthalmic surgery. Because the anesthetic is deposited outside the muscle cone, the potential for intraocular or intradural injection is greatly minimized. Furthermore, intraconal hemorrhage and direct optic nerve injury is avoided. We illustrate the details of our technique for posterior peribulbar anesthesia and describe our experience in over 1,600 cases.
