ABSTRACT
PURPOSE: Spontaneous superior ophthalmic vein thrombosis (SOVT) is a rare entity. We describe three patients with spontaneous ophthalmic vein thrombosis, each with various risk factors. PATIENTS AND METHODS: A retrospective review of three patients with a diagnosis of superior ophthalmic vein thrombosis. Clinical characteristics, radiographic features, management techniques and outcomes are described. RESULTS: All patients presented with unilateral painful proptosis. Two patients had intact light perception, whereas one patient presented with absent light perception. All patients had identifiable risk factors for thrombosis, which included sickle cell trait, hereditary hemorrhagic telangectasia and colon cancer with recurrent deep vein thrombosis. Anticoagulation was initiated in two patients. Resolution of proptosis was seen in all patients, with no recovery of vision in one patient. CONCLUSIONS: Risk factors for spontaneous superior ophthalmic vein thrombosis are multifactorial. MRI and MRV confirm the diagnosis of SOVT. Despite urgent intervention devastating visual loss may occur.
