摘要：
A method of treating glaucoma in an eye by managing fluid flow past an implanted shunt having an elastomeric plate and a non-valved elastomeric drainage tube. The plate is positioned over a sclera of the eye with an outflow end of the elastomeric drainage tube open to an outer face of the plate. An inflow end of the drainage tube tunnels through the sclera to the anterior chamber of the eye. The plate may have regions of greater propensity for cell adhesion alternating with regions of lesser cell adhesion. For example, regions of texturing around the plate or drainage tube may be provided to control the size of a bleb that forms over the implant. The effective surface area of the plate may be balanced against a number of fenestrations. The drainage tube has a reduced profile and may be shaped with a non-circular external cross-section to reduce its height. A scleral groove may be used to further reduce the height of the drainage tube on the sclera. A flow restrictor for the early post operative period will immediately lower the intraocular pressure (IOP) and simultanously prevent hypotony.
