One-year outcomes of combined phacoemulsification and viscogoniosynechialysis with and without endoscopic cyclophotocoagulation in primary angle-closure glaucoma

Purpose To compare the outcomes of combined phacoemulsification and viscogoniosynechialysis (VGSL) with and without endoscopic cyclophtocoagulation (ECP) in primary angle-closure glaucoma (PACG). Methods In this prospective interventional case series 52 eyes of 50 patients were enrolled. Twenty-seven eyes underwent combined phacoemulsification and VGSL (PV group) and 25 eyes underwent the same procedure plus circumferential ECP (PVE group). All eyes were followed 1 day, 1 week, 3 months, 6 months, and 1 year after the procedure. Intraocular pressure and antiglaucoma medications were compared between and within groups using generalized estimating equations. Kaplan–Meier survival analysis was carried out to compare intensity to failure between groups. Results The mean ± SD age was 63.23 ± 6.87 years and 50% of the cases were male in the entire group. Intraocular pressure (IOP) and antiglaucoma medications were significantly reduced at all time points in comparison with the baseline in both groups ( p < 0.05). There was no significant difference between groups in either IOP or medications at specific time points ( p > 0.05). One eye in each group developed a fibrinous reaction in the postoperative period. There was no statistically significant difference between groups regarding the intensity to failure ( P = 0.169). Conclusion There were no significant differences in IOP and medication reduction between groups. Also, the complications were comparable between groups.
