Reversal of visual loss due to optic neuropathy and exudative retinal detachment after closure of a traumatic carotid-cavernous fistula

ABSTRACT

To report a case of traumatic carotid-cavernous fistula [CCF] in whom loss of vision was reversed after closure of the fistula. Case report. A 15-year-old female had a 12-day history of visual loss, proptosis, and redness in the right eye after sustaining trauma to the head in a road traffic accident. Examination revealed the presence of optic neuropathy and exudative retinal detachment. Angiography demonstrated a CCF. Vision was completely restored and exudative retinal detachment resolved after closure of the fistula. Although CCFs frequently are associated with permanent visual loss, a subset of patients demonstrates reversible ocular findings:
