Surgical Technique: Pars Plana Ahmed Glaucoma Valve Implantation
نویسندگان
چکیده
The pars plana model of the Ahmed Glaucoma Valve (AGV) is inserted into the vitreous cavity through a sclerostomy, and has a specially designed clip anchors that it in place and avoids tube kinking. The tube deliver aqueous from within the eye to the episcleral plate covered by Tenon’s capsule and conjunctiva, which stimulates fibrovascular encapsulation around the plate. This article elucidates the technique of its implantation, and critically evaluates its efficacy in refractory glaucomas.
