Abstract

Introduction: Valved Glaucoma Drainage Devices (GDDs) such as the Ahmed device were designed to offer better pressure dependent  aqueous outflow control. These have traditionally been reserved for recalcitrant glaucoma, though there’s increasing  evidence that they are just as effective and safe as Trabeculectomy[1,2]. This study highlights the authors experience with Ahmed tube  implant in Nigerian patients.

Methods: This was a retrospective case series  in which we reviewed the outcome of Ahmed Glaucoma Drainage Implant (GDI)  surgeries in the University College Hospital (UCH), Ibadan, Nigeria between July 2010 and Dec 2015. Main outcome measures included  intraocular pressure (IOP), use of adjunctive medical therapy and surgical complications. Absolute success was defined as achieving  target pressure without adjunctive medical therapy or further surgery.
