Sequential glaucoma drainage implants markedly reduce IOP, medication use

PHILADELPHIA — Second glaucoma drainage implants significantly reduced IOP and medication use but had a high failure rate, according to a study presented here. “Trabeculectomies have always been the gold standard for glaucoma surgery … but the rates of tube shunt surgery have been going up in the past decade significantly, especially with publication of the Tube Versus Trabeculectomy Study, which showed that Baerveldt tube shunts have about the same IOP lowering as trabeculectomy,” Wanda D. Hu, MD, said at the Wills Eye Annual Conference.
