Molteno drainage implant for neovascular glaucoma
Neovascular glaucoma is the most difficult form of glaucoma and responds poorly to medical treatment and conventional filtering procedures. Neovascular glaucoma most commonly occurs after a central retinal vein occlusion or in association with proliferative diabetic retinopathy. It is a secondary glaucoma caused by the development of fibrovascular tissue growing over the surface of the iris and trabecular meshwork. The Molteno drainage implant described in 1977 was used in 36 ages with neovascular glaucoma and the methods and results are described.
