[Congenital fibrosis syndrome. Considerations on etiology, genetics and surgical therapy]

Fibrosis syndrome has been a well-known clinical entity for more than a century.

On the basis of their experience in 12 cases (2 unilateral, 10 bilateral, 7 with eye muscles and/or lid surgery), the authors attempt to help answer these questions.
