[Haemodynamic problems and eye (author's transl)].

Haemodynamic problems of ocular circulation are discussed with regard to blood pressure measurment in the eye, giving information about the blood circulation of the internal carotid artery. Investigations on the choroidal and retinal circulations show that, between these two tissue layers, the movement of extravascular fluid predominates from the choroidal capillaries to the retinal capillaries. A model of the pressure relationships in both of these vascular systems is constructed to substantiate this hypothesis.
