BACKGROUND: To evaluate the efficacy in controlling intraocular pressure (IOP) with endoscopic cyclophotocoagulation (ECP) versus implantation of a second glaucoma drainage device (GDD-2) in the treatment of uncontrolled glaucoma with a prior aqueous tube shunt. DESIGN: A nonrandomized retrospective chart review. PARTICIPANTS: Patients with refractory glaucoma following a failed initial tube shunt (Baerveldt Glaucoma Implant 350), who underwent ECP or GDD-2 with Baerveldt Glaucoma Implant as a second surgery. Twenty-five eyes underwent ECP, and 48 eyes received a GDD-2. METHODS: ECP or second tube-shunt surgery. MAIN OUTCOME MEASURES: Reduction in IOP and antiglaucoma medications, and Kaplan-Meier survival with success defined as lOP ≥ 5 mmHg and ≤ 21 mmHg and ≥ 20% reduction from preoperative IOP. Secondary outcome measures were visual acuity and the presence of any postoperative complications. RESULTS: Both ECP and GDD-2 significantly lowered IOP (Student's t test) and number of antiglaucoma medications (Wilcoxon paired signed rank test). There were no significant differences in postoperative IOP (Student's t test) or antiglaucoma medications (Mann Whitney test) between ECP and GDD-2 at 6 and 12 months. There was also no difference in the Kaplan-Meier survival outcomes between the two groups. CONCLUSION: Both ECP and GDD-2 are both effective as second surgeries for refractory glaucoma that has failed a prior aqueous shunt.
