[Regulation of intraocular pressure and haemodynamics in patients with severe polytrauma (author's transl)]

In 18 polytraumatized patients injuried by an accident, the intraocular pressure was measured and the aqueous humour production and regulatory capacity were determined by means of the perilimbal suction cup with simultaneous recording of haemodynamic parameters. The measurements were carried out 1. in the immediate acute stage, 2. in the period of circulatory recovery, and 3. under stable circulatory conditions. It became evident that the production of aqueous humour was suspended in the acute stage. With improving stabilization of the circulatory system, the aqueous humour minute volume and the regulatory capacity of the eye were raised. The cause of the reduction of both these parameters in the acute stage of a polytrauma has to be seen in an affection of the intraocular vascular nervous system in dependence of the general shock situation.
