Outcomes of Ahmed Glaucoma Valve Implantation in the Ciliary Sulcus Versus the Anterior Chamber

The authors aimed to compare the surgical outcomes of Ahmed glaucoma valve (AGV) implantation through the ciliary sulcus (CS) versus the anterior chamber (AC) in terms of intraocular pressure (IOP) control and corneal endothelial cell loss. Their findings indicate that while AGV-CS implantation has similar success rates for IOP control as AGV-AC, it is associated with more intraoperative challenges and postoperative hyphema, yet results in significantly less corneal endothelial cell loss. Thus, with proper technique, CS can be a viable option for refractory glaucoma treatment.
