Correlation of fundus lesions and hematologic findings in leukemic retinopathy.
This prospective study evaluated the relationship between the fundus findings in leukemic retinopathy and hematologic parameters. Seventy-four newly diagnosed consecutive patients with acute leukemia were included, 49 with acute myelocytic leukemia (AML), and 25 acute lymphocytic leukemia (ALL). Blood parameters were based on data obtained before starting any therapeutic modalities. Leukemic retinopathy was detected in 32 patients (43%). Patients with ALL and retinal hemorrhages had significantly lower hemoglobin and hematocrit levels than those without hemorrhages (p = 0.004 and 0.018 respectively). AML patients with white-centered hemorrhages had a significantly higher leukocyte count than those without (p = 0.0002). ALL patients with cotton-wool spots had significantly lower hemoglobin levels and hematocrit than patients without such lesions (p = 0.044 and 0.05 respectively). AML patients with cotton wool spots had significantly lower leukocyte and platelet counts than those without (p = 0.019 and 0.003 respectively). Our results suggest that anemia is related to the findings of retinal hemorrhage and cotton-wool spots in ALL patients, that high leukocyte count is associated with white centered hemorrhage in AML patients, and that thrombocytopenia is not associated with retinal hemorrhage in this group of patients.
