[Corneal dystrophies]

Corneal dystrophies are rare and have multiple clinical expressions. Some of them are isolated, without any systemic background, and often familial; they evolve slowly with opacification or deformation of the corneal stroma or with recurrent erosions; treatment consists of corneal grafting which generally has a favourable outcome. Other corneal dystrophies are manifestations of a systemic metabolic disorder; they are often associated with other ocular lesions and their prognosis is rather poor.
