[Some aggregation parameters in the bulbar vessels used for assessing the clinical course of retinopathy in patients with essential hypertension and diabetes mellitus]. / Nekotorye pokazateli agregatsii v bulbarnikh sosudakh v otsenke klinicheskogo techeniia retinopatii u bolhykh gipertonicheskoi bolezníu i sakharnym diabetom.

The aggregation status of the blood in the bulbar vessels was assessed by computer analyzer system of television images of the eye (CASTIE) in 10 patients with hypertensive angiosclerosis, 22 with diabetic proliferative retinopathy, and 15 patients without vascular abnormalities. The aggregation gradients of intravascular bloodflow in the venules were increased and aggregation coefficients in the bulbar veins decreased in the patients with vascular diseases of the retina, this indicating disorders of blood aggregation. CASTIE helps assess the degree of disorders in blood aggregation at the level of the intravascular and parietal bloodflow and single out the groups at risk of developing thrombotic complications of the retina among the patients with essential hypertension and diabetes mellitus.
