Neovascular glaucoma is commonly treated surgically with implantation of glaucoma drainage devices. We report the case of a 57-year-old man who underwent an uneventful Ahmed glaucoma valve (AGV) placement for radiation-induced neovascular glaucoma but later developed early postoperative infection with tube exposure. The infection was identified 3 weeks postoperatively and antibiotic treatment w...

We report the MR imaging findings of an unusually large fluid collection, so-called giant reservoir, around an Ahmed glaucoma valve implant that caused progressive proptosis in a patient with posttraumatic glaucoma. Although other cystic lesions of the juxtalacrimal area of the orbit, such as dermoid cyst, can present similar imaging findings, the characteristic morphology and location should l...

CASE REPORT We report the case of a 29-year-old man who underwent Ahmed valve implantation in both eyes as treatment for uveitic glaucoma, subsequently presenting with bilateral ocular decompression retinopathy in the postoperative period. DISCUSSION Ocular decompression retinopathy is a rare complication of filtering surgery in patients with glaucoma; however, the course is benign in most ca...

OBJECTIVE To compare 2 commonly used aqueous drainage devices for the treatment of refractory glaucoma. DESIGN International, multicenter, randomized trial. PARTICIPANTS Patients aged 18 years or older with uncontrolled or high-risk glaucoma refractory to maximum medical therapy, many of whom had failed trabeculoplasty and trabeculectomy. METHODS Eligible patients were randomized to an Ah...

PURPOSE To evaluate the results of Ahmed glaucoma valve surgery in neovascular glaucoma and control patients. METHODS In this retrospective comparative study, we reviewed 76 eyes of 76 patients, comparing the surgical outcomes in control patients (N=38) to matched neovascular glaucoma patients (N=38). Success was defined as intraocular pressure (IOP) > or =6 mm Hg and < or =21 mm Hg, without ...

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 ...

PURPOSE To evaluate the efficacy and safety of Ahmed Glaucoma Valve (AGV) implantation with adjunctive use of preserved amniotic membrane for surgical management of refractory glaucoma. METHODS Seven patients (5 female subjects) with refractory glaucoma were included in the study. An AGV (model FP7) was implanted in the usual manner and was covered with two layers of cryopreserved human amnio...

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...
