purpose: to evaluate the effect of early aqueous suppressants initiation on ahmed glaucoma valve success rate. methods: in this randomized clinical trial, a total of 94 eyes of 94 patients with refractory glaucoma were enrolled. the eyes were randomly selected into 2 groups. in group 1 (n=47), patients received early topical combination of timolol-dorzolamide twice daily after ahmed glaucoma va...

PURPOSE To compare the surgical results of trabeculectomy and Ahmed glaucoma valve implantation after a previous failed trabeculectomy. METHODS A retrospective comparative case series review was performed on 31 eye surgeries in 20 patients with primary congenital glaucoma who underwent trabeculectomy or Ahmed glaucoma valve implantation after a previous failed trabeculectomy with mitomycin C....

PURPOSE To compare the histopathologic and morphologic findings of encapsulated blebs following Ahmed glaucoma valve implantation and primary standard trabeculectomy with mitomycin-C. METHODS We reviewed the records of patients with otherwise uncontrollable glaucoma who had undergone Ahmed glaucoma valve implantation or trabeculectomy with mitomycin-C. Five eyes that underwent Ahmed valve imp...

purpose : to examine the safety and efficacy of simultaneous ahmed glaucoma valve (agv) implantation with intravitreal and intracameral injection of bevacizumab (ivb and icb) in patients with refractory acute neovascular glaucoma (nvg) with very high intraocular pressure (iop) and active neovascularization of the iris (nvi) and/or the angle (nva) methods : in a prospective interventional study,...

PURPOSE Long-term intraocular pressure reduction by glaucoma drainage devices (GDDs) is often limited by the fibrotic capsule that forms around them. Prior work demonstrates that modifying a GDD with a porous membrane promotes a vascularized and more permeable capsule. This work examines the in vitro fluid dynamics of the Ahmed valve after enclosing the outflow tract with a porous membrane of e...

Purpose. Cyclectomy/trabeculectomy and Ahmed glaucoma valve implant are operations suggested for refractory glaucomas. In this study, we have evaluated the outcomes that we observed with these two techniques in neovascular glaucoma patients. Material and Methods. Thirty-five eyes with neovascular glaucomas were included in this study. Ahmed Glaucoma valve (group A) was applied to ten eyes, whil...

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...

PURPOSE To report a case of Propionibacterium acnes endophthalmitis in a patient with an Ahmed glaucoma valve. CASE REPORT A nine-year-old boy with bilateral congenital glaucoma, with an Ahmed glaucoma valve implanted in the left eye, had recurrent conjunctival dehiscence and endophthalmitis. RESULTS Vitreous cultures demonstrated the presence of Propionibacterium acnes. CONCLUSIONS This ...

purpose: to evaluate the early and intermediate outcomes of ahmed glaucoma valve implantation in pediatric glaucoma at labbafinejad medical center. methods: this was a retrospective chart review of 101 eyes of 80 consecutive patients with pediatric glaucoma who underwent ahmed glaucoma valve implantation. success was defined as an intraocular pressure less than 21 mmhg with or without medicatio...

BACKGROUND To investigate the surgical results of Ahmed valve implantation with intravitreal triamcinolone acetonide injection (IVTA) in patients with aphakic or pseudophakic glaucoma. METHODS Fifty-nine patients who underwent Ahmed valve implantation were consecutively recruited from November 2005 to August 2011 at the Beijing Tongren Hospital. In the IVTA group (29 eyes), 4 mg of TA was inj...
