Experiences with trepano-trabeculectomy.

The technique, results, and possible mode of action of trepano-trabeculectomy were presented. In our hands the operation proved to be relatively easy to perform, to be free of consequential complications, and effective in normalizing the intraocular pressure. It should be emphasized that the presented results apply only for this type of trabeculectomy. Black patients appear to respond better to this than to other antiglaucomatous procedures.
