title: Internal glaucoma drainage device tube fenestration for uncontrolled postoperative intraocular pressure.
abstract: OBJECTIVE
  To describe a novel approach to early postoperative intraocular pressure (IOP) control after glaucoma drainage device (GDD) implantation.
  
  
  METHODS
  Two patients with elevated IOP after GDD implantation underwent internal GDD tube fenestration using a 30-gauge needle to perforate the GDD tube.
  
  
  RESULTS
  IOP was lowered in each case by over 50% without complication.
  
  
  CONCLUSIONS
  Transanterior 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.
