As intraocular pressure is increased, facility of aqueous outflow decreases. For many years
this fact was obscured by the often used procedure of experimental perfusion into the
anterior chamber. Anterior chamber perfusion deepens the anterior chamber;
retrodisplacement of the iris-lens diaphragm tenses the trabecular mesh with resulting
facility increase and obscuration of the facility-reducing effect of pressure. The probable
mechanism of facility reduction under experimental conditions is apposition of the inner wall …
