[The cicatrization of corneal wounds].

The tissular mending of the corneal surface is the result of a complex series of various physiopathological responses. This structural regeneration involves a primary reconstruction and a secondary one. The primary reconstruction of the barrier function provides the restoring of the normal equilibrium of osmotic, thermal and metabolic exchanges. The primary cicatricial response's goal is the fast coating of the corneal plague and mainly involves an inflammatory response. The major stages of this initial sequence are: the migration of the polynuclear neutrophils into the plaque, the establishment of a fibrinous cork, the collapsing and then the migration of the epithelial cork, and the contraction of the keratocyte mesh.
