[Physical symptoms in the orbit during ophthalmodynamography (author's transl)].
Analysing physical process occurring in the orbit during ophthalmodynamography the author comes to the conclusion that the "systolic pressure" as recorded ophthalmodynamographically is not a real pressure present in the ophthalmic artery, but a sum of this pressure and of that which is necessary to overcome the resistence of the orbital tissues. A considerable influence of the blood flow in the system of the external carotid artery is explained by superficial localisation of arterial branches belonging to the system and consequently by direct transmission of volume and pressure changes in the blood flow to the registering device, practically without damping effect of the orbital tissues.
