Dr. Christopher Teng and Dr. Kenneth Schor demonstrate the placement of a glaucoma tube extender to extend a previous glaucoma tube implant. This case is a combined case with the retina surgeon. This patient developed a retinal detachment and needed silicone oil placement. The previously placed supertemporal Baerveldt implant was removed and it was extended, using a Model TE (Tube Extender) from New World Medical, and placed in the inferotemporal quadrant. The tube is then covered with Amnioguard amniotic membrane.
