[Role of the trabecular meshwork in chamber water exchange based on model experiments].

On the basis of our experiments with models, we suppose that the trabecular meshwork possesses a pump mechanism with a sucking and compressing effect, forming a basic hydrodynamic mechanism together with the humour aqueous production and the uveal and episcleral outflow. This mechanism is able - in spite of the changes of certain factors - to keep the aqueous outflow and the intraocular pressure at a standard level in normal physiologic circumstances. Finally, it is possible that this mechanism can be influenced by the neurohormonal system, or in other words, it may be the physical manifestation of the neurohormonal effects.
