Corneal limbus
Corneal Limbus
The Corneal Limbus (kohr-nee-uhl lim-buhs) is a vital part of the human eye. It is the border area where the cornea, the clear, dome-shaped surface that covers the front of the eye, meets the sclera, the white part of the eye.
Etymology
The term "limbus" comes from the Latin word for "border" or "edge". The corneal limbus is so named because it forms the border between the cornea and the sclera.
Function
The corneal limbus plays a crucial role in maintaining the health and clarity of the cornea. It is the location of the limbal stem cells, which are responsible for the continuous renewal of the corneal epithelium, the outermost layer of the cornea. These cells also play a role in wound healing when the cornea is injured.
