Summary

Aseptic cavernous sinus thrombosis (CST) is rare and may clinically masquerade as a carotid cavernous fistula. Conventional management includes oral anticoagulation, but cases of ocular hypertension affecting vision may require more aggressive intervention. We report a case of a woman with spontaneous bilaterally occluded cavernous sinuses with elevated intraocular pressure (IOP), which resolved immediately following unilateral superior ophthalmic vein (SOV) sacrifice. She was subsequently placed on oral anticoagulants. By 4 months postoperatively her IOP was normalized and her vision had improved. Repeat angiography demonstrated stable venous filling, with some mild improvement of flow through the cavernous sinus. Coil-mediated sacrifice of the SOV might be an effective means to relieve ocular hypertension and preserve vision in the setting of aseptic CST.
