Trabeculectomy: Histological and clinical comparisons of the anterior and posterior approaches

Abstract

Trabeculectomy is an effective surgical method for controlling glaucoma. Histologic examination of operative specimens can be performed most effectively with scanning electron microscopy. An anterior approach has been developed and is described. It is easier and safer to perform than the posterior approach, and is equally effective in pressure control. Neither removal of the canal of Schlemm, nor bleb formation are prerequisites for intra-ocular pressure control. The peri-operative use of antiglaucoma treatment did not affect long-term results.
