Abstract:
We report a case of a 47-year-old female who experienced periorbital swelling while descending from a Himalayan mountain climb and was found to have bilateral superior ophthalmic vein thromboses (SOVT). Infectious, autoimmune, and hypercoagulability work-up were negative with no cavernous sinus involvement. Symptoms resolved upon initiation of anticoagulation and oral steroids. SOVT is a rare but serious condition and has a risk of extending into the cavernous sinus if not treated early. Although infection is the most common etiology, venous thrombosis can be precipitated under high altitude and low oxygen pressure environments. We present a case of superior ophthalmic vein thrombosis associated with high-altitude conditions.
