Ahmed Glaucoma Valve Implantation with Ologen augmentation in secondary pediatric glaucomas: A 2-year randomized controlled trial. Background: Many studies have investigated the clinical benefits of Ologen for trabeculectomy. However, its benefits for Ahmed glaucoma valve implantation have not been widely investigated. Purpose: The aim of this study was to compare the 2-year outcomes of AGV implantation with and without Ologen adjuvant for the treatment of children with 2ry pediatric glaucoma. Design: This is a single-center, randomized, controlled study. Participants: Consecutive children with refractory pediatric glaucoma requiring AGV implantation were enrolled in this study. Methods: Refractory pediatric glaucoma was defined by at least 2 repeated IOP measurements greater than 21 mmHg and accompanying signs of buphthalmos, corneal edema, Haabs striae, or optic nerve cupping despite maximal tolerated medical therapy. The primary outcome measure was AGV success. Complete success was defined as intraocular pressure (IOP) between 6 and 20 mmHg without glaucoma medications and additional IOP-lowering surgeries. Qualified success was defined as above, except IOP control maintained with glaucoma medications. In Ologen eyes, a round 12 × 1 mm circular Ologen disc will be placed over the FP7 or FP8 AGV-plate immediately before conjunctival closure. Control eyes received conventional FP7 or FP8 AGV surgery without Ologen augmentation.
