Internal glaucoma drainage device tube fenestration for uncontrolled postoperative intraocular pressure.
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.
