ANGULUS IRIDIS Meaning and
Definition
-
Angulus iridis, commonly known as the iridocorneal angle, is a term used in anatomy and ophthalmology to describe a specific region within the eye where the cornea and the iris meet. It refers to the angle formed by the junction of the cornea, the clear front part of the eye, and the iris, the colored portion of the eye that regulates the size of the pupil.
Located in the periphery of the anterior chamber of the eye, the angulus iridis plays a crucial role in the drainage system of the aqueous humor, a clear fluid that fills the front part of the eye and maintains intraocular pressure. It is through this angle that the aqueous humor flows out of the eye. The proper functioning of the angulus iridis is vital to maintain a healthy balance of intraocular pressure and prevent conditions such as glaucoma, where the fluid drainage becomes impaired, leading to increased pressure inside the eye.
Clinicians and ophthalmologists often evaluate the angulus iridis during eye examinations to assess its structure, width, and any signs of abnormalities. Various diagnostic techniques, such as gonioscopy, are employed to visually inspect the angle and determine its characteristics. Understanding the angulus iridis and its role in intraocular fluid dynamics is crucial for diagnosing and managing conditions affecting the drainage system of the eye.
