Résumé
Treatment of corneal epithelial diseases induced by limbal stem cell deficiency is an important challenge in ocular surface reconstruction. Since the 1990s, corneal stem cells have been localized in the limbus. This new concept completely changed the way we consider ocular surface reconstruction, with new diseases now found to be isolated in the ocular surface. Limbus insufficiency syndromes are specific depending on their origin (congenital or acquired), their expression (unilateral or bilateral, partial or total), their progression (acute or chronic), and the mechanism involved (burn, infection, chronic inflammation, etc.). Some of these diseases are local diseases and others are systemic diseases. Clinically, limbus insufficiency is a switch of the normal corneal epithelial phenotype (expression of a specific keratin, avascularity, and transparency of the corneal matrix) in an opaque and fibrovascularized cornea. In terms of cellular biology, a phenotype is a terminal expression of a cell differentiation process. This process is the outcome of the interaction between the genome of a cell or a group of cells with their microenvironment. In limbus insufficiency, epithelial cells and corneal matrix are destroyed, and it is the destruction of these two components that leads to limbus insufficiency syndrome.
