Implantation of Ahmed glaucoma valve is an effective surgical technique to reduce intraocular pressure in patients affected with glaucoma. While in the past, the use of this device was reserved to glaucoma refractory to multiple filtration surgical procedures, up-to-date mounting experience has encouraged its use also as a primary surgery for selected cases. Implantation of Ahmed glaucoma valve...

AIMS To compare outcomes of resident-performed Ahmed valve surgery vs trabeculectomy in a Veteran Affairs medical facility. MATERIALS AND METHODS A retrospective cohort of 103 eyes in 91 patients receiving Ahmed valve (valve) or trabeculectomy (trab) performed at a Veterans Administration Medical Center by residents in their third year of training. The primary outcomes included intraocular pr...

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...

BACKGROUND Neovascular glaucoma is a refractive glaucoma. Recently, anti-VEGF factors have been used alone or in combination for the treatment of neovascular glaucoma. However, the medium- and long-term efficacy of such drugs remains to be evaluated. This study was to determine the efficacy of intravitreal ranibizumab combined with Ahmed glaucoma valve implantation for the treatment of neovascu...

PURPOSE To describe clinical results of Ahmed glaucoma valve implantation in Mexican patients with neovascular glaucoma (NVG). MATERIALS AND METHODS We reviewed records of 60 eyes of 60 patients with NVG who underwent Ahmed valve implantation, with a follow-up period of 1 year. We identified successful and failed cases and compared baseline and follow-up characteristics to identify possible d...

PURPOSE Ahmed glaucoma valves were implanted into the ciliary sulcus of two patients diagnosed with neovascular glaucoma with favorable outcomes. METHODS The study patients presented to our hospital with ocular pain caused by increased intraocular pressure (IOP). A thorough history was taken, and an ophthalmic examination was performed. RESULTS A 71-year-old male patient and a 57-year-old f...

AbstractGlaucoma management in pregnant patients is a real challenge, especially when the glaucoma is not controlled with medications. We report the results of 6 incisional glaucoma surgeries for the management of medically uncontrolled glaucoma patients during pregnancy. This retrospective, case series was conducted on the 6 eyes of 3pregnant patients with uncontrolled glaucoma using maximum t...

This study was designed to investigate whether 5-fluorouracil (5-Fu)-polycaprolactone sustained-release film in Ahmed glaucoma valve implantation inhibits postoperative bleb scarring in rabbit eyes. Eighteen New Zealand white rabbits were randomly divided into three groups (A, B and C; n = 6 per group). Group A received combined 5-Fu-polycaprolactone sustained-release film application and Ahmed...

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...
