Comparative Study, Safety and Efficacy, Ahmed Glaucoma Drainage Device, Model M4 Model S2 in Neovascular Glaucoma

May 29, 2024 updated by: Asociación para Evitar la Ceguera en México

Comparative Study of the Safety and Efficacy of the Ahmed Glaucoma Valve Drainage Device, Model M4 (High Density Porous Polyethylene) and the Model S2 (Polypropylene) in Patients With Neovascular Glaucoma

Objective: Prospectively evaluate the safety and efficacy of the Ahmed Glaucoma Drainage Device, model M4 compared with the model S2.

Method: Mexican patients with Neovascular Glaucoma will be randomly included for each group (M4 and S2). They will be operated using conventional techniques and creating a sub-episcleral tunnel to place the valve's tube in the anterior chamber. They will be monitoring for one year and the results will be evaluated with respect to a postoperative reduction in pressure, changes in visual acuity, the need for drugs and complications, in addition to the demographic characteristics of each group.
