330 trabeculectomies--a follow-up study through 1/2-3 years.

In 1967 a new microsurgical procedure for glaucoma known as trabeculectomy was introduced. This method is reported to have few early complications and a good pressure-reducing effect. Our material presents the results of 330 consecutive trabeculectomies with a follow-up period of 1/2-3 years. The following items are discussed: IOP, visual acuity, visual fields, surgical complications, and need of re-operation and medical postoperative therapy. We conclude that trabeculectomy is a safe and efficient antiglaucoma operation, recommended as an attractive alternative to heavy medication.
