We have studied 93 cases of trabeculectomy, most of them performed on primary chronic open angle glaucomas, with a follow up of 2 to 11 years. Reviewing of the results point out that intraocular pressure stabilization over a long time period is correlated to the existence of an effective subconjunctival filtering bleb. Recurrence of hypertension increases with time, but most of the cases are stabilized by medical treatment, or by laser trabeculoplasty, when it is possible. Cataract producing concerns 46% of the cases, happening within one to three years in most of them. It is greatly influenced by patients age. On the other hand, effective subconjunctival filtering bleb and transient post operative athalamy are not major factors.
