Background. Non-penetrating trabeculectomy is used as the surgical intervention for open angle glaucoma. It has advantage of creating gradual filtration through the thin trabeculo-Descemet membrane to reduce markedly the postoperative complications typical for penetrating operation. We described our experience of the non-penetrating trabeculectomy for open angle glaucoma. Methods. This is a retrospective study of 28 eyes of 28 patients with primary open glaucoma (POAG). Non-penetrating trabeculectomy was performed by one surgeon from July 1998 to March 2000. Examinations were performed preoperatively and postoperatively in 1 and 7 days and 1, 3, 6, 12 and 21 months. Results. The mean follow-up was 12.5 ± 6.3 months (S.D.). The mean preoperative intraocular pressure (IOP) was 27.8 ± 6.7 mmHg. The mean postoperative IOP was 11.5 ± 6.2 mmHg in 1 day and 15.7 ± 5.8 mmHg in 1 week, and it remained stable in the following 12 months. IOP of 71.3% (20/28) of the eyes could be controlled below or equal to 21 mmHg with no or only topical antiglaucoma medication. There were only few postoperative complications. Conclusions. Non-penetrating trabeculectomy is efficient in controlling intraocular pressure of open angle glaucoma. No entering the anterior chamber diminishes the postoperative complications typical of the penetrating trabeculectomy.
