Procedural treatments: Glaucoma drainage devices

Abstract

Since the principle goal of tube shunt surgery is to lower IOP, the answer to this question easily could be considered the main factor in selecting a device. However, no one shunt has become the predominant choice of glaucoma surgeons, yet. The reason for this may be that there is not a clearly superior design with regards to IOP, that there is a superior design but the available evidence does not reveal this fact, or that factors other than IOP lowering ability influence a surgeons' selection of device. © 2010 Springer-Verlag Berlin Heidelberg.
