Intraconal [Retrobulbar] anesthesia: evaluation of two different techniques

Two types of needles either straight or curved were used for retrobulbar block during eye surgery the study included 1000 patients classified into 2 groups [group I: 480 patients] we used straight needle for retrobulbar block, [group II: 520 patients] we used curved needle for their retrobulbar block. No major complications occurred in both groups. Side effects in group I [straight needle] were chemosis 30.21%, subconjuntival hemorrhage 4.17%, lid hemorrhage 2.08%, Side effects in group II [curved needle] were chemosis 48.08%, subconjuntival hemorrhage 5.77% and lid hemorrhage 3.85%. We concluded that retrobullbar route using straight or curved needle was a safe and a successful technique
