Combined viscocanalostomy-trabeculectomy for management of far-advanced glaucoma: evaluation of the early postoperative course.

BACKGROUND AND

OBJECTIVE

To study the early postoperative efficacy and safety of combined viscocanalostomy with trabeculectomy (VISCO-TRAB) for treating far-advanced glaucoma.

PATIENTS AND

METHODS

Patients with far-advanced glaucoma scheduled for glaucoma surgery were enrolled in the study. Surgery included viscocanalostomy until Schlemm's canal was deroofed and dilated with viscoelastic, followed by penetrating corneotrabeculectomy, peripheral iridectomy, and tight closure of lamellar flap. Patients with severe glaucoma who were treated with trabeculectomy only (TRAB) in the preceding year were used for comparison.

RESULTS

The study included 39 eyes in the VISCO-TRAB group and 40 eyes in the TRAB group. Mean intraocular pressure was significantly lower in the VISCO-TRAB group during the early postoperative period (P < .05). The postoperative course was less eventful in the VISCO-TRAB group with minimal hypotony or suture lysis-related complications.

CONCLUSION

During the early postoperative period, VISCO-TRAB proved efficacious and safe in reducing intraocular pressure to target levels in patients with far-advanced glaucoma.
