Pannus(redirected from corneal pannus)
Also found in: Dictionary, Medical.
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.
