Hypertensive choroidopathy in atypical hemolytic-uremic syndrome.

Although multiple organ systems are commonly affected in hemolytic uremic syndrome, ocular involvement has only been described in very few cases. Ocular manifestations in atypical hemolytic uremic syndrome include retinal, choroidal and vitreal hemorrhages, retina and/or ischemic signs. Bilateral serous retinal detachment may also be a sign of atypical hemolytic uremic syndrome or even the first manifestation of a hypertensive event.
