anterior chamber
Fluid-filled space between the cornea and iris containing aqueous humor.
Full Definition
The anterior chamber is the fluid-filled space in the front portion of the eye, bounded by the cornea anteriorly and the iris and lens posteriorly. It contains aqueous humor, which provides nutrition to surrounding tissues and maintains intraocular pressure. The depth and angle of the anterior chamber are clinically significant in glaucoma assessment and cataract surgery planning. Shallow chambers may predispose to angle-closure glaucoma, while deep chambers may indicate certain types of glaucoma or developmental anomalies. Surgical procedures often involve entry into or manipulation of this space.
Usage
Usage note: Often abbreviated as AC in clinical notes. Specify depth measurements when relevant.
