Purpose: To evaluate the safety and efficacy of viscocanalostomy in the management of medically uncontrollable primary open-angle glaucoma (POAG) in a developing country. Materials and Methods: This is a prospective, non-randomized case series of 14 consecutive eyes with medically uncontrollable POAG, all subjected to viscocanalostomy. The main outcome measure was success rate based on the intraocular pressure (IOP) level achieved post-operatively. The procedure was considered a complete success if IOP was less than 21 mmHg without any anti-glaucoma medication. Qualified success was defined as IOP of less than 21 mmHg with anti-glaucoma medication. All patients had a regular follow-up of at least 12 months. Results: IOP was reduced from a mean baseline value of 27.9 ± 7.3 mmHg (range: 21-40 mmHg) to a mean final value of 16.0 ± 2.7 mmHg (range: 13-22 mmHg), which was statistically highly significant (P < 0.005). The mean number of pre-operative anti-glaucoma medications was 3.0 ± 0.4 (range: 2-4), which was reduced significantly (P < 0.0001) to 0.3 ± 0.6 (range: 0-2) at the last follow-up visit. One year post-operatively, complete success was achieved in 71% and qualified success was observed in 21.4% of patients, summing up to an overall success rate of 92.4%. There were no major complications in any of the patients. Conclusion: Viscocanalostomy could be performed effectively and safely for control of POAG in developing countries.
