To study the possible role of an "increased thrombotic tendency" in the vascular complications of diabetes several tests of haemostatic function were carried out on 91 men and 63 women with diabetes aged 35-54 years and the results compared with findings in 686 men and 393 women of the same age in the Northwick Park Heart Study. Mean values for factors VII and X, fibrinogen, and platelet adhesiveness were higher in the diabetics, but mean fibrinolytic activity and whole blood platelet counts were lower. Antithrombin III values were also higher in the diabetics, which may have constituted a protective response to other changes favouring the onset of vascular disease. Diabetics with retinopathy had higher factor VII and antithrombin III values, and those with proteinuria had higher values for factor VII, fibrinogen, and platelet adhesiveness than those without these complications. These findings suggest a potentially important association between a thrombogenic tendency and vascular disease in diabetes. Nevertheless, prospective data are needed to clarify whether the haemostatic abnormalities precede the onset of clinically manifest vascular complications or are a consequence of them.

The influence of a disturbed hemostasis as one of the causes of retinal or ciliary vascular occlusions is still controversial. Antithrombin III, protein C and its cofactor protein S were investigated in 25 patients; 14 of them with a retinal vein occlusion, five showed an occlusion of retinal arteries and six of ciliary arteries. Patients with a preceding thromboembolic disease were excluded from the investigations. The mean values (+/- SEM) of antithrombin III (12.1 IU/ml +/- 0.4), protein C (116% +/- 4), total protein S (102% +/- 3) and free protein S (46% +/- 2) were equivalent to the mean values of a normal population. Neither does a defect or a lack of coagulation inhibitors have an essential influence on the development of an isolated retinal or ciliary vascular occlusion nor does the local occlusive vascular disorder influence the activity of systemic inhibitors.
