In patients suffering from arteriosclerosis and its complications, special patterns of the small vessels in the conjunction and nailbed are described and illustrated. These patterns may serve as signs aiding in the diagnosis of arteriosclerosis. The patterns in conjunctiva or nailbed were found in over 80 per cent of patients with clinical arteriosclerosis and in 36 per cent of persons over the age of 56 without clinical arteriosclerosis. In younger patients the pattern was seen in arteriosclerosis and in hypertension. In arteriosclerosis the arterioles and arteriolar limbs of the capillaries were moderately narrowed. In the conjunctiva the ratio of arteriole to venule diameter became 1:3 and may reach 1:6 or more. Severe capillary narrowing is uncommon in arteriosclerosis. In hypertension severe capillary narrowing (diameter less than 3.5 �) is common. Blood pressure in terminal digital vessels in arteriosclerosis is normal. In severe hypertension it is very high.
