How to intubate the eye in severe glaucoma?

A new approach for the treatment of serious and/or uncurable glaucoma is proposed by the adjonction of a drain, cut in a crinotube, with micro-perforations and set in the classical opening of a trabeculectomy. In four years, for nine cases of particularly severe hypertonia, we observed one relative unsuccess, three real and stable improvements during two years and then with the necessity of local treatment (for rather young patients), and five clear and till today durable improvements. We have also observed a very good local tolerance for all cases, with never a persisting major hypotonia. This simple and efficient process seams susceptible to find its room in the treatment of severe hypertonia.
