Permanent blindness following retrobulbar hemorrhage after peribulbar anesthesia for cataract surgery.

We present a case in which a modified peribulbar anesthesia, administered with a 24-gauge (0.55 x 25 mm) sharp, disposable needle, induced an orbital hemorrhage, resulting in complete and permanent loss of vision. To our knowledge, this is the first report of severe complications following a peribulbar block.
