A transient, ipsilateral central retinal artery occlusion and contralateral amaurosis developed following retrobulbar injection of 2% lidocaine and 0.75% bupivacaine.

This case further supports the view that intranerve sheath injection can cause these two complications associated with retrobulbar anesthesia.
