Retinopathy of blood dyscrasias.
BACKGROUND: Retinopathy often accompanies blood dyscrasias. METHODS: Three cases are presented: 1) a 75-year old patient with anemia of chronic disease, extensive posterior pole hemorrhaging and ischemic changes, 2) a 70-year old patient in whom retinopathy was the presenting sign of his chronic myelocytic leukemia and 3) a 56-year old patient with polycythemic retinopathy and papilledema. RESULTS AND CONCLUSIONS: These unusual cases are presented with a general discussion of retinal vascular manifestations of blood dyscrasia.
