Purpose: To report long-term success of surgical correction of exposed glaucoma drainage device (GDD) tubes with a commercially available tube extender. Design: Observational case series. Methods: Chart review of surgical correction for GDD tube exposure by rerouting the tube using the New World Medical Tube Extender (NWMTE; New World Medical, Rancho Cucamonga, California, USA). Results: Surgical revision of GDD tube exposure with the NWMTE controlled intraocular pressure without repeat exposure up to three years after surgery. Conclusions: A tube extender can provide long-term correction of an exposed GDD tube by bypassing weakened tissue, thus avoiding or delaying a second implant surgery.
