The purpose is to evaluate the effectiveness and safety of Ahmed valve implantation in children with refractory postuveitic glaucoma (PUG). Material methods . was implanted 10 aged 7 17 years (10 eyes) open-angle or mixed PUG uncompensated even by a maximum antihypertensive mode. Previously, all patients had undergone an average 2.1 ± 0.9 surgeries aimed at normalizing intraocular pressure (IOP...

Ahmed Glaucoma Valve Implantation is an important armamentarium in the management of refractory glaucoma like pseudophakic glaucoma in pediatric age group [1]. Though effective, complications are not uncommon [2,3]. However conjunctival dehiscence is relatively rare and previously has not been reported in this age group. Here we present a case of failed repair of conjunctival dehiscence over co...

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 elucidate...

PURPOSE To estimate the incidence of hypertensive phase (HP) following silicone plate Ahmed glaucoma valve implantation and to explore the risk factors for developing HP. METHODS A total of 325 eyes from 325 patients who underwent Ahmed glaucoma valve implantation for uncontrolled intraocular pressure (IOP) and were followed for at least 1 year were included. The HP was defined as IOP>21 mm H...

OBJECTIVE To evaluate the results of Ahmed Glaucoma Valve implantation in African American and white patients. METHODS In this retrospective, comparative case-control study, we reviewed 86 eyes of 86 patients, comparing the surgical outcomes in white patients (n = 43) with matched African American patients (n = 43). Success was defined as an intraocular pressure (IOP) between 6 mm Hg and 21 m...

AIM To evaluate the long-term results and complications of ahmed glaucoma valve (AGV) implantation in refractory glaucoma. METHODS A retrospective review of 13 patients (13 eyes) with refractory glaucoma who underwent AGV implantation and had a minimum follow-up of 18 months was performed. All patients underwent a complete ophthalmologic examination and intraocular pressure (IOP) measurement ...
