[Aging changes in conjunctival blood vessels]. 1985

H Siprová, and L Vacek

The relation of the changes in the conjunctival blood vessels to the age were studied in a group of 217 persons aged 20 to 79 years. All persons suffering from arterial hypertension, diabetes, systemic diseases and manifested forms of arteriosclerosis were excluded. It has been proved that examination of the conjunctival blood vessels by means of the slot-lamp facilitates the study of the changes in the microscopic blood vessels in relation to the age. Most conspicuous was the increase of the meander course of the blood vessels, also the increasing number of blood vessels is more frequent in the group of older persons. Clusters of vessels and a narrowing of the diameter of the arterioles was seen only in persons over fifty years of age. The "upright" course of the arterioles was found only in individual cases and without any special dependence to age. Sacculations on the small veins and microaneurysms on the arterioles were not observed in any of the examined group of healthy persons.
