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 < 0.001) and 10.0 mmHg at 1.5 years (p < 0.001). Average medication burden decreased from 3.8 to 1.7 at 1.5 years (p = 0.001). No significant differences in visual acuity were observed at any time point. No long-term sight-threatening complications due to the combined procedure were observed, and most of the complications observed were mild and transient. CONCLUSION: In patients with refractory glaucoma, the combination of augmented MP-TSCPC with limited CW-TSCPC provides a significant IOP-lowering effect and decrease in medication burden without increased risk of postoperative complications.
