The anterior chamber is larger than the posterior chamber and is the area of the eye from the back of the cornea to the iris.
Through a small gap between the iris and the lens, the aqueous humor flows from the posterior chamber into the anterior chamber and finally drains in the peripheral area of the eye (the chamber angle), where the iris and cornea meet.
Through this small canal (Schlemm’s canal), the aqueous humor is directed into the bloodstream. If this drainage is impaired, intraocular pressure can increase, and the risk of glaucoma rises.
