POSTERIOR CHAMBER Meaning and
Definition
-
The posterior chamber is a term used in anatomy and medicine to describe a specific region within the eye. It is a small space located between the iris, the colored part of the eye, and the lens, a transparent structure responsible for focusing light onto the retina. The posterior chamber is filled with a watery fluid, known as the aqueous humor, which circulates around the eye, maintaining intraocular pressure and providing essential nutrients to various structures.
The main function of the posterior chamber is to help maintain the shape and structure of the eye. It acts as a cushioning agent, providing support and protection to delicate structures like the lens and the retina. It also plays a crucial role in regulating intraocular pressure, ensuring that the pressure within the eye remains within a normal range.
The posterior chamber is a highly dynamic space, as it constantly produces and drains aqueous humor. The fluid is produced by the ciliary body, a structure located behind the iris, and it flows through the posterior chamber before exiting through the drain, called the trabecular meshwork, at the angle between the cornea and the iris.
Overall, the posterior chamber is a vital component of the eye, participating in the regulation of intraocular pressure and maintaining the overall health and function of the eye structures.

Etymology of POSTERIOR CHAMBER
The word "posterior" comes from the Latin word "posterus", meaning "coming after" or "behind". The term "chamber" originates from the Latin word "camera", which initially referred to a vaulted room or small dwelling. In the context of anatomy, a chamber refers to a hollow or enclosed space within a structure.
Therefore, "posterior chamber" in the medical field refers to the space or cavity located behind another structure. In particular, the term is commonly used to describe the posterior chamber of the eye, which is a space filled with aqueous humor located behind the iris and in front of the lens.
