Arteriovenous fistula induced by a peribulbar nerve block.
Arteriovenous fistula (AVF) of the head and neck region is an uncommon clinical condition that can be of congenital or acquired etiology. We report a case of AVF of the left supraorbital vessels that developed after a peribulbar nerve block was given for cataract surgery.
