Abstract
A viscometric study of blood from insulin-treated diabetics separated into three clini.cal groups (without retinopathy, with minimal retinopathy and with moderate or severe retinopathy) has been carried on. Among the studied viscometric parameters, three of them, relative to red blood cells (RBC) aggregation, have been found to be more modified in patients with retinopathy than in those without. The results involve (i) a more difficult break off of the blood structure, (ii) a more rigid network structure, (iii) a strong trouble of the rouleaux disaggregation process. These modifications are found closely linked to plasmatic disorders. Furthermore, the deformability of diabetic RBC, evaluated by viscometry is found decreased.
