Anterior chamber of eyeball

The anterior chamber of eyeball is the fluid-filled space inside the eye between the posterior surface of the cornea and the anterior surface of the iris and the central part of the lens. It forms part of the anterior segment of the eye and contains aqueous humor, a clear fluid that maintains intraocular pressure and provides nutrients to avascular ocular structures.

Anteriorly, the anterior chamber is bounded by the corneal endothelium, while posteriorly it is bounded mainly by the iris and, in the pupillary region, by the anterior surface of the lens. Peripherally, the anterior chamber forms the iridocorneal angle (a.k.a. the anterior chamber angle), which contains the trabecular meshwork and scleral venous sinus (canal of Schlemm), important structures for aqueous humor drainage.

Aqueous humor is produced by the ciliary processes in the posterior chamber, passes through the pupil into the anterior chamber, and drains through the trabecular meshwork into the canal of Schlemm. This circulation helps maintain normal intraocular pressure and optical clarity.

The normal depth of anterior chamber of eye 3.5mm to 2.5mm.
