CORNEAL LIMBUS Meaning and
Definition
-
The corneal limbus, commonly known as the limbus or the corneoscleral junction, refers to the area where the transparent cornea meets the white sclera of the eye. It is the outermost edge of the cornea and is located at the border between the clear front part of the eye and the opaque outer part. The corneal limbus is crucial for maintaining the structural integrity and functionality of the eye.
Anatomically, the corneal limbus is characterized by a gradual transition from the transparent cornea to the opaque sclera, with distinctive features that differentiate it from the adjacent regions. It often appears as a slightly raised, circular ridge that encircles the cornea. The limbal area contains specialized cells, such as limbal stem cells, which play a major role in regenerating and repopulating the cornea. These stem cells are essential for the continuous renewal of the corneal epithelium, which is the outermost layer of the cornea.
Functionally, the corneal limbus is responsible for several important processes. It serves as a barrier between the external environment and the inner structures of the eye, protecting the delicate cornea from foreign particles, infections, and other potential damages. Additionally, the limbus is responsible for maintaining the structural stability and shape of the cornea. It houses blood vessels that provide nourishment to the cornea and facilitates the exchange of nutrients and waste products. Furthermore, the corneal limbus contains specialized nerve endings that contribute to the sensory perception of the eye, such as pain and touch sensations.

Etymology of CORNEAL LIMBUS
The word "corneal" is derived from the Latin word "cornea", which means "horn-like" or "like a horn". The cornea is the clear, dome-shaped surface that covers the front of the eye.
The term "limbus" also comes from Latin and means "border" or "margin". In the context of the eye, the corneal limbus refers to the border or transition area between the cornea and the white part of the eye called the sclera. It is where the transparent cornea merges with the opaque sclera.
