Abstract:

Abstract Clinical case We report a case of a 31 - year - old woman with a sudden visual loss due to a cilioretinal artery occlusion . The physical examination showed hepatomegaly . Serum iron and ferritin and transferrin saturation were unusually high . The Doppler scan of carotid arteries showed no relevant signs of atheromatous disease . Dilated cardiomyopathy was revealed in the B - scan with subendocardial calcium deposits . Genetic tests were positive for hemochromatosis . Discussion Subendocardial calcification due to hemochromatosis could be the embolic source in our patient . This embolic ocular disease is the first presentation of hemochromatosis in this patient .
