[Therapeutic failures in indirect injuries to the optic nerve].

Making an analysis during five years, the authors find a great number of atrophies of optic nerve after indirect trauma on the orbital area or an the head, questioning if the treatment applied had been correct. Studying the literature they find the same feeble results and controversial opinions regarding the therapy of these cases. On tried treatments with macrodoses of dexamethazone i.v., the opening of optic nerve's health or of the optic nerve's duct, the vacating of the retrobulbar haematomas, but the results remained unsatisfying. The problem is if we must console ourselves that the others have the same feeble results or we must try to add to the conservatory treatment applied till now the neurosurgical investigations of the optic duct and heaths of the optic nerve, especially when the vision is lowering progressively and especially when the other eye is also implied.
