[Trabeculectomy: surgical technique, results, indications (author's transl)]. 1977

B Gloor, and W Niederer, and B Daicker

In this teaching-course special emphasis is given on surgical techniques and postoperative care of trabeculectomy. The follow-up of 114 eyes of 103 patients is reported. High tension in the early postoperative phase allowed no prediction of the later results. After 3 months 11%, and after one year 39% of the operated eyes with simple glaucoma had a tension higher than 22 mm Hg, even if drugs were given. Different sites of the excision in regard to the trabecular meshwork and Schlemm's canal gave no statistically different results. The filtering blebs have the tendency to develop in two directions, either scarring or becoming cystic. The cystic filtering blebs give better functional results. The development of the filtering bleb was inversely proportional to the height of the tension but went parallel to the facility of outflow. The visual acuity diminished in 35%, mostly due to cataract-formation and improved in 3%. Different complications happened in 6%. The authors consider the trabeculectomy to be the operation of choice for almost all forms of glaucoma.

D005901	Glaucoma	An ocular disease, occurring in many forms, having as its primary characteristics an unstable or a sustained increase in the intraocular pressure which the eye cannot withstand without damage to its structure or impairment of its function. The consequences of the increased pressure may be manifested in a variety of symptoms, depending upon type and severity, such as excavation of the optic disk, hardness of the eyeball, corneal anesthesia, reduced visual acuity, seeing of colored halos around lights, disturbed dark adaptation, visual field defects, and headaches.
