BACKGROUND Paediatric aphakic glaucoma presents months or years after cataract surgery in children and is a major long term complication. The results of surgical treatment are poor and many children require multiple and repeat procedures with poor visual outcomes. METHODS 13 children (19 eyes) had Ahmed valve implantation surgery, nine of the children had previous procedures such as cycloabla...

OBJECTIVE To create and test a slow-release antifibrotic drug-coated glaucoma drainage device using in vitro and in vivo experiments. METHODS A slow-release device incorporating mitomycin C in poly(2-hydroxyethyl methacrylate) disks was developed using redox-polymerization techniques. A standardized preparation of this drug delivery device was attached to the Ahmed glaucoma valve (model FP7; ...

We present our experience with implantation of an Ahmed glaucoma valve in a 9-year-old girl with Sturge-Weber syndrome with choroidal hemangioma. In this case of childhood glaucoma, the choice of surgical procedure should be based on the efficacy and elimination of intra-and post-operative complications. An Ahmed glaucoma valve offered safety and efficacy in controlling glaucoma. This technique...

AIMS To evaluate the efficacy and safety of the Ahmed glaucoma valve implant in Chinese eyes with complicated glaucomas. METHODS This retrospective study reviewed the final intraocular pressure, visual outcome, and incidence of complications in all patients with the Ahmed glaucoma valve implant performed at the Prince of Wales Hospital, Hong Kong, between June 1996 and November 1998. RESULT...

purpose: to compare the efficacy and safety of ahmed glaucoma valve (agv) implantation in the superior versus inferior quadrants. methods: this prospective parallel cohort study was performed on 106 eyes of 106 patients with refractory glaucoma. main outcome measures included intraocular pressure (iop) and rate of complications. other outcome measures included best-corrected visual acuity (bcva...

PURPOSE To describe clinical findings after Ahmed valve drainage implantation in children. DESIGN All records in one practice were reviewed to identify and describe clinical findings in all children who had undergone Ahmed Glaucoma Valve S2 model insertion for uncontrolled primary or secondary glaucoma. RESULTS A total of 6 patients were identified, ranging in age from 2-15 years. Mean foll...

INTRODUCTION The purpose of this study was to determine whether the outcomes following placement of a fluocinolone acetonide implant (Retisert(®); Bausch & Lomb, Inc.) combined with an Ahmed™ glaucoma valve (New World Medical, Inc.) in eyes with uveitic glaucoma (UG Retisert) were different when compared to an Ahmed valve alone in eyes with uveitic glaucoma or primary open angle glaucoma (UG no...

PURPOSE To describe short term outcomes of Ahmed Glaucoma Valve [AGV] implantation in East African patients. MATERIALS AND METHODS In this multi-center retrospective case series we reviewed eyes of Black African patients with refractory glaucoma, treated consecutively with Ahmed Glaucoma Valve implantation, in two centers in Kenya between January 2006 and October 2007. RESULTS About 25 case...

Surgical management of elevated intraocular pressure (IOP) in an eye with scarred conjunctiva, an encircling band, and silicone oil has limited options. By combining the flow restrictor of the Ahmed Glaucoma Valve (New World Medical, Rancho Cucamonga, California) and the capsule of the encircling band as a conduit for aqueous flow, immediate pressure reduction could theoretically be achieved in...
