OBJECTIVE: To introduce an anti-glaucoma filtering surgery, modified trabeculectomy, which may have a continuous drainage of the aqueous. DESIGN: Retrospective, comparative case series. PARTICIPANTS: 41 patients (51 eyes) with primary open angle glaucoma. METHODS: Remove a perpendicular scleral flap along with the trabecular meshwork and followed with a peripheral iridectomy and tenonnectomy. The excision of a portion of Tenon's capsule ensures that the superior end of the tunnel remains open. Patients were followed over one year period. The therapeutic efficacy of the modified operation versus traditional operation were compared. Main outcome measures: Pre-and post-operative intraocular pressure(IOP), uncorrected visual acuity (UCVA), best-corrected visual acuity (BCVA), postoperative bleb formation and postoperative complications. RESULTS: A total of 41 patients (51 eyes) were included in this study. Chronic open angle glaucoma was the most common type of glaucoma. During the one-year follow-up, 97.2% (25/26) of the modified operation treated eyes achieved IOP below 20 mmHg and 76.0% (19/25) of traditional operative procedure, below 21 mmHg. The postoperative BCVA in both groups did not show significant changes. CONCLUSION: In the modified surgery, a perpendicular sclera strip with trabecular meshwork was excised. Postoperative IOP was reduced and visual acuity remained stable. IOP may be controlled for a long term in modified trap procedure, which seems to be a safer and more effective treatment for open angle glaucoma. LA: Chinese
