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.
管腔阻塞是青光眼引流植入物的一种公认并发症。在纠正阻塞的管腔时，即使在去除怀疑的阻塞原因后，外科医生也可能无法确定分流器的功能。我们报告了使用台盼蓝染料在修复阻塞的 Baerveldt 管后直接显示管腔通畅性。
