Childhood or pediatric glaucomas are a heterogeneous group, comprising the true primary developmental glaucomas, associated with developmental anomalies in the eye since birth and other secondary glaucomas. Early onset primary open angle glaucoma, the so called juvenile glaucoma, as well as angle closure glaucomas both primary and secondary are also seen in the pediatric age group. Pediatric gl...

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...

OBJECTIVES The purpose of this study was to identify risk factors for exposure of glaucoma drainage devices (GDD). SETTING This retrospective, observational study was conducted in the eye clinic of an academic medical centre. PARTICIPANTS Participants included 1073 consecutive adults who underwent GDD surgery between 1 January 2005 and 1 January 2011. Participants were included if chart rev...

AIM To describe the surgical management of glaucoma in a patient with severe scleromalacia, and secondary angle closure. INTRODUCTION The management of glaucoma with coexisting scleromalacia plus secondary angle closure is challenging as most commonly performed incisional glaucoma surgery as well as minimally invasive glaucoma surgery (MIGS), which targets the drainage angle are all contraind...

Purpose Retinal changes secondary to hypotony are usually described as wrinkling or folding of the inner portion of the choroid, the retinal pigment epithelium (RPE), and the outer retinal layers in the macular area due to scleral wall collapse. We describe a new retinal finding in children with suspected hypotony after implantation of Baerveldt Glaucoma Implant (BGI). Observations Four patie...

OBJECTIVE To describe an alternative method to repair exposed glaucoma drainage devices (GDDs) when conventional attempts have failed. METHODS Four eyes, from 3 patients, with severe ocular surface disease were included in the study. All eyes had previously received a Baerveldt GDD for uncontrollable intraocular pressure and postoperatively had exposed GDDs. The conjunctival defects were unre...

PURPOSE ExPress devices are available as P50 and P200 models, the numbers related to their luminal diameters in μm. We compared their Poiseuille's Law-based theoretical resistance values with experimental values and correlated these with their luminal dimensions derived from electron microscopy. METHODS Scanning electron microscopy was performed on P50 and P200 devices. Bench-top flow studies...

Purpose. Tube-related exposure is a known complication of glaucoma drainage device (GDD) surgery. Our objective is to report the early (approximately 1 year) tube exposure rate of implants covered with a keraSys (IOP Inc., Costa Mesa, CA, USA) tissue reinforcement graft. Patients and Methods. A retrospective, noncomparative, consecutive case series of 42 eyes with GDD implantation with keraSys ...
