The Limbus: Where the Cornea Meets the Sclera
Definition
The limbus is the border between the cornea and the sclera, the white part of the eye. It is a narrow zone that prevents the opaque conjunctiva from invading the cornea, which is essential for clear vision.
Clinical Significance
The limbus is clinically significant because it is the site of frequent inflammation and other eye conditions. In types 1 and 2 limbal inflammation, the limbus is swollen and neovascularized, which can lead to corneal scarring and vision loss. Corneal dermoids, benign growths that can obstruct vision, also commonly arise from the limbus.
