Bilateral Central Retinal Vein Occlusion in a Patient With Occult Colon Cancer

Arch Ophthalmol. 2001;119(10):1552-1553. doi:

Cancer is known to be a hypercoagulable state as described initially by Trousseau in 1865.1 The mechanism is not well understood. Among the thrombotic events that may accompany tumors, ophthalmic thrombosis, especially retinal vein occlusion, is a known but uncommon phenomenon. However, simultaneous bilateral central retinal vein occlusion is quiet rare and was never described in the literature as a symptom of cancer.
