Anterior chamber angle

Anterior Chamber Angle is a part of the eye that plays a crucial role in the aqueous humor drainage system. It is located between the cornea and the iris, and its primary function is to facilitate the outflow of the aqueous humor from the eye to the bloodstream.

Etymology

The term "anterior chamber angle" is derived from its location and structure. "Anterior" refers to its position at the front of the eye, "chamber" signifies its role as a space for the aqueous humor, and "angle" describes its angular shape formed by the junction of the cornea and iris.

Structure

The anterior chamber angle is a critical component of the eye's drainage system. It is formed by the meeting of the peripheral iris and the cornea. The angle houses the trabecular meshwork, a spongy tissue that serves as the primary site for aqueous humor outflow. The Schlemm's canal, which is located within the angle, collects the aqueous humor drained through the trabecular meshwork and delivers it to the bloodstream.

Function

The primary function of the anterior chamber angle is to facilitate the drainage of the aqueous humor, a clear fluid that nourishes the eye's tissues and maintains intraocular pressure. The aqueous humor is produced by the ciliary body, flows into the anterior chamber, and then drains out through the trabecular meshwork in the anterior chamber angle. This process is crucial for maintaining the eye's intraocular pressure and overall health.

Clinical significance

Abnormalities in the anterior chamber angle can lead to various eye conditions. For instance, a narrow or closed anterior chamber angle can impede the outflow of the aqueous humor, leading to increased intraocular pressure and potentially causing glaucoma. This condition, known as angle-closure glaucoma, is a serious eye disorder that can result in vision loss if not treated promptly.
