title: Trypan blue to assess Baerveldt tube patency after repair of its obstruction.
abstract: Tubal obstruction is a recognized complication of glaucoma drainage implants. In correcting a blocked tube, the surgeon may be uncertain about shunt competence even after removing the suspected cause of obstruction. We report the use of trypan blue dye to show tubal patency directly after the repair of a blocked Baerveldt tube.
