Purpose of the Study: The purpose of the study was to report long-term outcomes and complications of Baerveldt glaucoma implant (BGI) surgery with pars plana tube insertion in children. Materials and Methods: The medical records of consecutive aphakic and pseudophakic children (<16 y of age) who underwent BGI surgery with pars plana tube insertion between 1990 and 2013 were retrospectively reviewed. Main outcome measures were intraocular pressure and number of glaucoma medications. Postoperative complications were recorded. Failure was defined as an intraocular pressure <5 or ≥21 mm Hg (with or without glaucoma medications), loss of light perception, or need for additional glaucoma surgery. Results: Thirty-seven children were identified with a mean age of 6.0±4.7 years (range, 4 mo to 14.5 y). Mean follow-up after pars plana BGI surgery was 6.5±3.4 years (range, 9 mo to 12.8 y) for patients who met success criteria. Mean intraocular pressure and mean number of glaucoma medications at most recent follow-up for patients with successful intraocular pressure control were 13.8±4.1 and 2.3±1.9 mm Hg, respectively. The Kaplan-Meier survival analysis revealed 1-, 3-, 5-, and 7-year success rates of 94.5%, 74.6%, 65.0%, and 45.8%, respectively. Complications included tube exposure in 1 patient (2.7%), tube obstruction in 8 patients (21.6%), and retinal detachment in 9 patients (24.3%). Seventeen patients (45.9%) failed due to inadequate intraocular pressure control, of whom 9 (24.3%) required additional glaucoma surgery. Conclusions: Although pars plana BGI surgery is a reasonable option for managing refractory glaucoma in aphakic and pseudophakic children, surgeons must be aware of the potential need for additional glaucoma surgery and/or posterior segment complications with extended follow-up.
