Chambers of the Eye

There are three distinct and interconnected chambers found inside the eyeball:

• The anterior chamber occupies the space between the corneal endothelium (anterior boundary) and the anterior surface of the iris, the pupillary portion of the lens, and the base of the ciliary body (posterior boundary). The circumferential angle of the anterior chamber is occupied by the trabecular meshwork, a drainage site for the aqueous humor into the canal of Schlemm.
• The posterior chamber is limited anteriorly by the posterior surface of the iris and posteriorly by the lens and the zonular fibers (suspensory ligaments of the lens). The circumferential angle is occupied by the ciliary processes, the site of aqueous humor production.
• The vitreous cavity is occupied by a transparent gel substance-the vitreous humor-and extends from the lens to the retina. The vitreous humor contains mostly water (99%), hyaluronic acid, and collagen fibers, both produced by hyalocytes.
