title: Pretrabecular filtration for secondary glaucoma.
abstract: The available drainage procedures in cases of glaucoma cause many early and late postoperative problems, including non-formation of the anterior chamber, excessive hypotony, changes in the lens, and unsafe filtering blebs. New microsurgical techniques involving the area of trabecular meshwork and Schlemm's canal include trabeculotomy, sinusotomy, and trabeculectomy. In a new drainage procedure devised by us a covered filtering track is created, which opens in front of the trabecular meshwork. This procedure, designated "pretrabecular filtration", has been a standard primary procedure in all types of glaucoma in our hospital for the last 3 years.
