Non-Needle Retrobulbar Local Anesthesia Technique for Optic Nerve Sheath Fenestration Procedures

Over the past 8 months, we have come to rely on non-needle local anesthesia for a significant percentage of our optic nerve sheath fenestrations. This operation is performed via local infiltrative anesthesia thereby avoiding the potential risks of general inhalational anesthesia to a compromised (at times a marginally perfused) optic nerve
