Implantable glaucoma drainage device

Patent Granted Professor Anthony Molteno developed the first glaucoma drainage implant, in Cape Town in 1966.[2] Following on the success of the Molteno implant, several varieties of device have been developed from the original, the Baerveldt tube shunt, or the valved implants, such as the Ahmed glaucoma valve implant and the later generation pressure ridge Molteno implants. These are indicated for glaucoma patients not responding to maximal medical therapy, with previous failed guarded filtering surgery (trabeculectomy). T
