The continuous-injection technique to reduce complications during retrobulbar anesthesia

Retrobulbar as well as peribulbar anesthesia remain relatively risky proced ures; retrobulbar hemorrhage and especially globe penetration or perforatio n can have blinding consequences. Our continuous-injection-technique greatl y reduces these risks whether used for retrobulbar or peribulbar anesthesia . If the ophthalmologist starts injecting the agent while advancing the nee dle, the fluid pushes tissues away, possibly preventing a hemorrhage. Since resistance against the plunger is instantaneously experienced if the needl e impacts the sclera, the ophthalmologist is adequately warned before actua l perforation of the sclera occurs.
