IRIDIAL ANGLE Meaning and
Definition
-
Iridial angle refers to the anatomical location where the iris, a colored muscular structure in the eye, meets the cornea, the clear front structure of the eye. It is the angle formed by the meeting of these two structures. The iridial angle, also known as the iridocorneal angle or the angle of the anterior chamber, plays a crucial role in the drainage and regulation of the fluid inside the eye.
The iridial angle contains several important structures, including the trabecular meshwork, Schlemm's canal, and the collector channels. These structures are responsible for maintaining the balance of fluid pressure inside the eye, allowing the aqueous humor (a clear, watery fluid) to drain properly. The proper functioning of the iridial angle is necessary for the prevention of elevated intraocular pressure, which can lead to conditions such as glaucoma.
The iridial angle can be examined by an ophthalmologist using specialized techniques such as gonioscopy. This evaluation allows for the assessment of the angle's openness or narrowness, which is crucial in the diagnosis and management of various eye diseases.
Understanding the iridial angle and its role in eye health is essential for the early detection and management of conditions affecting the drainage of fluid within the eye, aiming to prevent complications and preserve visual function.

Etymology of IRIDIAL ANGLE
The word "iridial angle" is a combination of two terms - "iridial" and "angle".
1. "Iridial" is derived from the word "iris", which refers to the colored muscular ring surrounding the pupil of the eye. The word "iris" comes from the Latin word "īris", which translates to "rainbow". This is because the iris often exhibits various colors, similar to the colors of a rainbow.
2. "Angle" is derived from the Latin word "angulus", meaning "corner" or "bend". It refers to the geometric concept of the space between two lines or surfaces that meet.
Therefore, the term "iridial angle" is used to describe the angle or configuration formed at the juncture of the iris with another structure or border, often in the context of ophthalmology or eye anatomy.
