Pannus

 

a morbid condition of the limbus and cornea of the eye resulting from a local chronic inflammation. It occurs most often in conjunction with trachoma but may also develop with tubercular-allergic keratoconjunctivitis. The infiltrate formed beneath the epithelium of the cornea is replaced by scar tissue; this causes a significant decrease in vision. Treatment consists of eliminating the primary disease. In the case of trachomatous pannus, surgery is recommended.

Because necrotic corneal tissue and corneal pannus can bring and attract inflammatory cells, which generate and release enzymes degrading corneal collagen and proteoglycans, we suggest that it is important to remove the necrotic corneal tissue and pannus before the suture of the corneal graft.
