목적 : To report a case with branch retinal vein occlusion (BRVO) in company with superior ophthalmic vein (SOV) thrombosis resultant from severe SOV enlargement in patient with graves’ ophthalmopathy (GO).
방법 : A 78 year-old woman diagnosed with BRVO presented with reduced vision. She had a history of unilateral graves’ ophthalmopathy before more than 20 years. Fluorescein angiography (FAG) and spectralis optical coherence tomography (OCT) revealed BRVO with cystoid macula edema. 5 months later, she complained of advanced left proptosis. Computed tomography (CT) scan showed dilated superior ophthalmic vein (SOV) with internal high attenuation by SOV thrombosis in the left orbit.
결과 : Because of uncertain onset of SOV thrombosis and minimal acute congestive orbital sign, we prescribed for her to take prophylactic daily aspirin for blood flow improvement instead of heprainization treatment. In addition, she was treated with lubricants for exposure keratopathy and dorzolamide/timolol eyedrop (Cosopt®) to prevent an intraocular pressure from increasing.
결론 : This is the first case to represent that venous stasis due to SOV enlargement in chronic severe GO can result in BRVO in company with SOV thrombosis leading to proptosis increase even in chronic stage of GO.
