Viscocanalostomy: Long Term Results

Abstract

Abstract: : Purpose: to evaluate in an open prospective ongoing study the long-term efficacy and safety of Viscocanalostomy. Methods: consecutive uncontrolled glaucoma patients fulfilling the inclusion and exclusion criteria underwent Viscocanalostomy. Uncontrolled primary open-angle and pseudoesfoliative glaucoma were included, while eyes with angle-closure, secondary or advanced glaucoma as well as subjects with legally blind fellow eye were excluded. Results: 100 eyes of 92 patients with 1-year minumum follow-up were included. Mean (SD) follow-up was 27.0 (16.1) months (range 12–60). Initial and final IOP were 26.2 (8.7) and 16.5 (6.7) mmHg respectively. At 54 months (Kaplan-Meier), an IOP [less than or equal to] 21 mmHg was achieved in 45% of the eyes and an IOP [less than or equal to] 16 mm Hg was achieved in 25% of the eyes, without additional laser or medication. At 54 months, qualified success (either with or without medication) was 85% for an IOP [less than or equal to] 21 mmHg and 35% for an IOP [less than or equal to] 16 mmHg. No major complications were found. Conclusions: Viscocanalostomy effectively and safely reduces IOP in open-angle glaucoma.
