Isolated Superior Ophthalmic Vein Thrombosis

The purpose of this article is to report a rare case of isolated superior ophthalmic vein thrombosis. A 74-year-old female presented to the emergency department with a sudden onset of eye pain and bulging. Ophthalmological examination was remarkable for proptosis and ptosis with chemosis of the OS. Neuroimaging demonstrated an isolated superior ophthalmic vein thrombosis secondary to presumed thrombosis of the superior vein varix. Hypercoagulable, infectious, and autoimmune lab workups were unremarkable. The patient was initiated on anticoagulation with the eventual resolution of her symptoms. Isolated superior ophthalmic vein thrombosis is an uncommon diagnosis that requires urgent evaluation to prevent vision loss. Risk factors are multifactorial with infectious being the most common etiology. Our case is unique in that there was no identifiable risk factor.
