What is the term for the border or margin where the cornea meets the sclera?

The term that defines the border or margin where the cornea (the clear front part of the eye) meets the sclera (the white outer coating of the eye) is known as the limbus. This anatomical structure plays a crucial role in eye health and function. The limbus contains stem cells that are responsible for the regeneration of the corneal epithelium and also provides a crucial barrier to infections. Additionally, the limbal region is significant because it is where the conjunctiva, the membrane covering the sclera and inner eyelid, also meets the cornea. Understanding this area is important for professionals in vision care as it is integral in various clinical procedures and the overall assessment of ocular health.
