Corneal limbus

Limbo (Latin for " border ", " seam ", " boundary " ), precise corneal limbus, called the transition zone between the cornea ( cornea) and sclera ( sclera ) of the eyeball. This region is home to stem cells for the epithelium and endothelium of the cornea and is required for their regular cell renewal. The peripheral parts of the cornea are supplied by fine, hairpin-like vessels of the limbal conjunctiva, the so-called edge loop network. Destruction of the Limbus - eg after severe burns or burns - can lead to an overgrowth of the cornea with Konjunktivagewebe and thus blindness of the eye. By Limbustransplantation from the healthy eye is attempted in such cases, to obtain the function of the cornea.

The limbus is the area of the eye that allows the best access to the eye muscles at a strabismus surgery ( Limbusschnitt ).
