The effect of hydroxyurea on blood viscosity was studied in 10 patients with Philadelphia chromosome positive chronic myelogenous leukemia (CML) and hyperleukocytosis (white blood cell counts over 200 x 10(9)/l). All the patients had visible manifestations of leukostasis such as headache, blurred vision, retinal hemorrhage, pulmonary infiltrates, etc. Contraves LS 30 viscometer was used to measure the blood viscosity at 37 degrees C and at different shear rates on paired leukemic blood samples obtained before and after the hydroxyurea treatment. The blood viscosity was significantly higher in CML patients then normal subjects and decreased after treatment with hydroxyurea. In all the cases plasma viscosity was unaffected by the treatment.

Complications caused by elevated white blood cell count in pediatric patients with CML could be a presenting feature of the disease. Here, we present two adolescents, aged 16 and 17years, who were admitted for investigation of extremely elevated leukocytes and complications of leucostasis. Initial manifestations were priapism and blurred vision, respectively. Diagnosis of chronic phase of chronic myeloid leukemia is established, and conventional measures for leucoreduction began. However, since there were no improvements, a leukapheresis procedure was initiated. After undergoing 3 daily procedures the leukocyte count declined for each patient, with resolution of pripaism and ophtalmological disturbances. Leukapheresis is safe and effective therapeutic option for patients with complications of hyperleucocytosis. If started in a timely manner, permanent organ damage or death could be avoided.

The current study reports a case of a patient with a chronic myelocytic leukemic fundus lesion, initially diagnosed in the Department of Ophthalmology, Rizhao People's Hospital (Rizhao, China). A male, 23-years-of-age, presented with a dark shadow in the front of the right eye, accompanied with blurred vision for 3 days (visual acuity of right eye, 0.4; visual acuity of left eye, 0.6). In addition, the patient had experienced gingival bleeding for 2 years, and recurrent upper respiratory infections for 1 year. A fundus examination revealed mild binocular papillary edema, dilated and tortuous veins, and the retina exhibited large quantities of scattered and dark red bleeding spots. The bleeding spots had white spots in the center, which exhibited typical Roth spots, whilst routine blood examination, abdominal ultrasound, marrow biopsy and other laboratory tests confirmed the diagnosis of chronic myelogenous leukemia. Patients with leukemia typically present with initial symptoms that include fever, fatigue, anemia and hepatosplenomegaly, and a diagnosis as a result of eye-related symptoms is rare, rendering the present case unique.
