The clinical significance of the reduced capillary resistance factor in the diabetic patient.
A statistical survey in a group of 235 subjects (174 diabetic patients and 61 nondiabetic control subjects) was conducted to evaluate the incidence of reduced capillary resistance factor in respect to diabetic disease, to its duration, and to the severity of retinopathy. To evaluate the capillary resistance we used a cupping-glass method (Parrot's angiosterrometer test). The incidence of reduced capillary resistance proved to increase in frequency with diabetes, with its duration, and with the severity of retinopathy. Thus, reduced capillary resistance represents a negative prognostic element for retinopathy.
