title: The dual chamber single plate implant--its use in neovascular glaucoma.
abstract: The insertion of an artificial draining implant consisting of a silicone tube, opening onto the upper surface of a circular episcleral plate, will provide long-term drainage in cases of neovascular glaucoma. A simple modification of the episcleral plate, the addition of a subsidiary pressure ridge, allows the episcleral tissues to function as a temporary pressure-sensitive valve which limits the escape of aqueous in the early postoperative period. The surgical technique used with this modified implant is described, together with the results in the first 24 eyes in which it has been used.
