title: Retrograde infusion of fluorescein to confirm location and patency of a glaucoma drainage device.
abstract: BACKGROUND
  During surgical revision of a glaucoma drainage device, the status of the implant tube can be in question. We report two cases in which retrograde infusion of fluorescein-stained balanced salt solution was used to confirm the patency and location of the tube.
  
  
  METHODS
  Fluorescein-stained balanced salt solution was made by dipping a sterile fluorescein strip into a 3-mL syringe of balanced salt solution until the fluid was visibly yellow. A 30-gauge canula was inserted into the tube at the reservoir end, and fluorescein-stained balanced salt solution was infused into the eye.
  
  
  RESULTS
  Retrograde infusion of fluorescein-stained balanced salt solution confirmed the location and patency of the glaucoma drainage device implant tube, obviating the need for more extensive surgical intervention in these two cases. Neither patient experienced an adverse event.
  
  
  CONCLUSIONS
  Retrograde infusion of fluorescein-stained balanced salt solution is a useful adjunctive technique for surgical revision of glaucoma drainage devices.
