Case ReportsOrbital supratrochlear fistula secondary to anaesthetic block in cataract surgery.
A case is described of a woman with history of right peribulbar nerve block prior to cataract surgery that, within a few days, presented with a trochlear intraorbital arteriovenous fistula. This was resolved without sequelae after three months by performing intermittent homolateral carotid massages. This is the first case of supratrochlear intraorbital arteriovenous fistula. There are only 8 cases reported of traumatic intraorbital arteriovenous fistula, and only one was with post-peribulbar anaesthesia.
