Retinal neovascularization after internal carotid artery occlusion.
OBJECTIVE
To report a case of retinal neovascularization after surgical ligation of the internal carotid artery for treatment of direct carotid-cavernous fistula.


METHODS
Case report.


RESULTS
A 44-year-old Asian woman presented with unilateral retinal neovascularization and vitreous hemorrhage. Surgical ligation of the ipsilateral internal carotid artery had been performed 14 years earlier as a treatment for carotid-cavernous fistula after failed attempts at fistula embolization. Vitrectomy was performed for removal of nonclearing vitreous hemorrhage, with intraoperative peripheral retinal ablation and cryotherapy of the lesion.


CONCLUSIONS
We report a case of retinal neovascularization associated with total occlusion of the ipsilateral internal carotid artery 14 years earlier.
