Central retinal vein occlusion associated with thrombotic thrombocytopenic purpura/ hemolytic uremic syndrome: complete resolution is possible.

We aim to describe a case of central retinal vein occlusion associated with this is a case report of a 45-year-old patient who was admitted for management of thrombotic thrombocytopenic purpura (TTP). He developed left central retinal vein occlusion three months later. The retinal vein occlusion resolved gradually as his TTP started to respond to medical treatment but significant macular edema persisted. Focal argon laser treatment resulted in complete resolution of the macular edema.
