PURPOSE: To determine the surgical outcomes of bleb needling and the risk factors of failure of needling after failed filtration surgeries in patients with pediatric glaucoma. METHODS: The medical records of patients who underwent needling with 5-fluorouracil following filtering surgeries (trabeculectomy, combined trabeculectomy, and trabeculotomy) between January 2012 and December 2016 were retrospectively reviewed. At the 1-year follow-up visit, complete success and qualified success were defined as an intraocular pressure (IOP) of less than 18 mm Hg with and without antiglaucoma medication, respectively. RESULTS: Forty-five eyes that underwent needling and fulfilled the study criteria were included in the analysis. The mean age at needling was 9.6 years. The mean time interval between filtration surgery and the first needling procedure was 57.3 days. Thirty-eight of 45 eyes (84.4%) had undergone needling within 3 months after the primary surgery. Cumulative success was achieved in 35 eyes (77.7%) after needling (complete success in 22 eyes and qualified success in 13 eyes). Mean follow-up after needling was 18.9 months. The mean IOP before and after needling was 31.7 ± 9.45 and 16.6 ± 5.68 mm Hg, respectively ( < .00001). Steroid-induced glaucoma ( = .01), high IOP prior to the first filtration surgery ( = .01), and an inability to achieve low IOP (< 9 mm Hg, = .04) immediately after needling were significant risk factors associated with failure. CONCLUSIONS: Bleb needling is an efficient method for lowering IOP after a failed trabeculectomy or combined trabeculectomy and trabeculotomy in the pediatric population.
