Outcomes of a combination of augmented MicroPulse and limited Continuous Wave Cyclophotocoagulation in patients with refractory glaucoma

Purpose To assess the safety and effectiveness of augmented MicroPulse (MP-TSCPC) with limited Continuous Wave Transscleral Cyclophotocoagulation (CW-TSCPC) in patients with refractory glaucoma. Methods Thirty-eight eyes of 38 patients underwent combined MP-TSCPC and CW-TSCPC at Massachusetts Eye and Ear. Kaplan–Meier survival curves and Wilcoxon paired sign rank tests were performed to evaluate intraocular pressure (IOP), glaucoma medication burden, best corrected visual acuity (BCVA), and adverse events. Results With success defined as IOP reduction ≥ 30% and IOP between 5 and 18 mmHg, the cumulative probability of success at 1 year and 1.5 years were 0.81 (95% confidence interval (CI), 0.68–0.96) and 0.65 (95% CI, 0.50–0.86), respectively. With success defined as IOP reduction ≥ 50% and IOP between 5 and 18 mmHg, the success probability at 1 year and 1.5 years were 0.72 (95% CI, 0.57–0.89) and 0.56 (95% CI, 0.40–0.78), respectively. IOP and medication burden reductions were significant at all follow-up visits compared to baseline. Average IOP decreased from 27.9 mmHg at baseline to 11.4 mmHg at 1 year ( p
