Experience with Ahmed Glaucoma Drainage Implant in Ibadan, Nigeria
Glaucoma
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.
