Internal Glaucoma Drainage Device Tube Fenestration for Uncontrolled Postoperative Intraocular Pressure

PurposeTo describe a novel approach to early postoperative intraocular pressure (IOP) control after glaucoma drainage device (GDD) implantation. MethodsTwo patients with elevated IOP after GDD implantation underwent internal GDD tube fenestration using a 30-gauge needle to perforate the GDD tube. ResultsIOP was lowered in each case by over 50% without complication. ConclusionsTransanterior chamber internal GDD tube fenestration is a novel, straightforward approach to early IOP control after GDD implantation. This procedure adds to our armamentarium of methods for controlling IOP during the early postoperative period.
