PURPOSE: Ahmed glaucoma valve (AGV) is an effective treatment method for refractory glaucoma (RG), however, additional surgical interventions may be required over the course of follow-up due to complications. Our aim is to investigate the causes, types, and outcomes of revisional surgical interventions apart from revisions aiming IOP control, following AGV implantation in patients with RG. METHODS: The pre- and postoperative month 1-3-6-12 and last visit examination findings of the patients who underwent various surgical revisions of AGV between January 2015 and April 2018 in our clinic were recorded, as well as the interval between AGV implantation-revision surgery and the presence of any other complications necessitating additional surgery. The success criteria were defined on the basis of need for additional procedures. RESULTS: Twenty-six eyes of 24 patients were included. The follow-up time and the interval between AGV implantation-surgical revisions were median 12 (6-92) and median 9.7 (1-72) months, respectively. The most common complication requiring revision was tube exposure in 15 (57.7%) followed by tube malposition in 11 (42.3%) eyes. Further interventions were required only in one eye with recurrent exposure. CONCLUSION: AGV implantation has early and late tube-related complications necessitating revisional surgical interventions; which makes it important to have extended follow-up period for patients with AGV implants. Revisional interventions for AGV implants with tube-related complications are efficient procedures for the majority of patients, but recurrence may occur requiring additional revisions.
