[Attempt to minimize postoperative trauma after trabeculotomy].
We tried to modify the technique of trabeculotomy in order to minimize the trauma to the anterior part of the eye, when tearing the trabecular meshwork. (1) With help of an annular probe, having a lumen, a nylon thread is pushed through Schlemm's canal and the trabecular meshwork cutted circumferentially. (2) With a 'flat probe', corresponding to the configuration of Schlemm's canal, the trabecular meshwork is torn. (3) A so-called 'hook probe' is described, which tears the trabecular meshwork while being sucessively pulled backwards. According to our experiments, the usefulness of the thread technique and of the 'flat probe' is not yet to be decided upon. On the other hand, the advantages of the 'hook probe' are clearly visible, in avoiding the complications connected with twisting the probe into the anterior chamber.
