Aim: To prospectively study the success rate and complications of the non-penetrating glaucoma surgery , viscocanalostomy.
Methods: 31eyes of 31 patients who had medically uncontrolled primary open angle glaucoma were enrolled in this prospective study, in which viscocanalostomy was performed on all patients with injection of viscoelastic (HEALON) in the surgically de-roofed Schlemm's canal and in the scleral bed, the superficial scleral flap was sutured and the conjunctiva tightly closed. Intraocular pressure, visual acuity, and visual field analysis were performed post operatively and recorded
Results: The Patients in this study were followed–up for a mean period of 21.2 months. The mean preoperative intraocular pressure (IOP) was 26.4 mmHg and the mean lOP on the first postoperative day was 8.4 mm Hg and 18.5 mmHg at the end of follow-up period (24 months). 67% of patients in this study achieved an lOP below 20 mmHg without medication ( complete success ), seven patients , 22.5% required medical treatment to achieve an IOP of < 20mmHg ,while 3 patients,9.6% required further surgical intervention to control their IOP.
Conclusion: Viscocanalostomy may be a good and promising surgical approach for glaucoma patients.
