OBJECTIVE: To compare the efficacy and safety of the Baerveldt® glaucoma implant (BGI) between a preserved donor scleral patch alone and double scleral flaps, comprising a preserved donor scleral patch and an autologous scleral pedicle flap. METHODS: This was an open-label retrospective study. We analyzed the cases of 52 consecutive patients (56 eyes) who underwent BGI surgery with the Hoffman elbow (#BG 102-350, Abbott) and were followed up for >1 year. Twenty-one eyes underwent BGI surgery with a preserved donor scleral patch alone (donor-patch group), and the other 35 eyes underwent BGI surgery with a preserved donor scleral patch and an autologous scleral pedicle flap (double-flap group)...

PURPOSE: Tube exposure remains one of the most common complications after glaucoma drainage device (GDD) implantation, despite various types of patch grafts available today. We present a 4 patient case series following the effectivity of the keratolimbal allograft (KLAL) as a patch graft for cases of tube exposure. Given its inherent population of stem cells, our hypothesis was that this highly replicative, biological tissue would provide an adequate means of glaucoma tube coverage. The subset of patients chosen for the KLAL patch graft all had a history of abnormally scarred conjunctiva or thin sclera...

PURPOSE: To evaluate the rate of the hypertensive phase (HP) post-Baerveldt implantation and association between HP and surgical outcomes. METHODS: This is a retrospective observational study of glaucoma patients who had Baerveldt implantation in 2004 and completed 18 months of follow-up. At 18 months of follow-up, medical records for HP and its associated factors, and surgical outcomes such as rate of failures, intraocular pressure (IOP), numbers of medications administered, and complications were reviewed and identified...

PURPOSE: To present a modified Descemet's stripping automated endothelial keratoplasty (DSAEK) technique to avoid risks of endothelial cell loss related to the presence of a glaucoma tube in cases with shallow anterior chamber. METHOD: A 72-year-old patient with an only eye and corneal decompensation secondary to a Baerveldt tube was referred for keratoplasty. He was pseudophakic and had shallow anterior chamber. His best-corrected visual acuity was counting fingers close to face...

PurposeTo report long-term outcomes of deep sclerectomy (DS) in eyes with raised intraocular pressure (IOP) and glaucoma secondary to uveitis.Patients and methodsRetrospective consecutive case series of 43 eyes of 43 patients with uveitic glaucoma. Mitomycin C (MMC) 0.2-0.4 mg/ml was applied sub-conjunctivally prior to scleral flap dissection for 2-3 min in 35 eyes (81%). Combined phacoemulsification and DS was done in 4 cases (9%).ResultsMean follow-up was 68.5±33.5 months. In total, 23 eyes (53.5%) had previous intraocular surgery...

Davinder S Grover, Ronald L Fellman
The authors have designed a muscle hook speculum that simultaneously allows the surgeon to isolate and expose both rectus muscles (either the superior and temporal or medial and inferior) for ease of placement of a 350-mm Baerveldt implant. This instrument facilitates the exposure and subsequent placement of either a superior-temporal tube or an infero-nasal tube in a more independent manner. By using the dual muscle hook speculum, an individual surgeon, without a glaucoma-trained assistant, can hook typically both the superior and lateral recti muscles while gaining simultaneous exposure of the quadrant...

IMPORTANCE: This study provides results of a treatment option for patients with failed primary glaucoma drainage device. BACKGROUND: The study aimed to describe and evaluate the long-term intraocular pressure control and complications of a new technique joining a second glaucoma drainage device directly to an existing glaucoma drainage device termed 'piggyback drainage'. DESIGN: This is a retrospective, interventional cohort study. PARTICIPANTS: Eighteen eyes of 17 patients who underwent piggyback drainage between 2004 and 2013 inclusive have been studied...

PURPOSE: Evaluate for normative postoperative magnetic resonance imaging (MRI) characteristics of a Baerveldt Glaucoma Implant (BGI). DESIGN: Prospective case series. PARTICIPANTS: Seven subjects with uncontrolled glaucoma requiring a primary superotemporal BGI.

This study aims to determine the course of vision loss after Baerveldt aqueous tube shunt placement and identify risk factors associated with unexplained severe long-term vision loss, or snuff-out. We retrospectively reviewed 247 eyes of 222 patients who underwent Baerveldt implantations at one of two academic institutions. Postoperative vision loss at 6 months following surgery was categorized as mild-to-moderate versus severe and long-term versus transient. Long-term vision loss, defined as 3 or more lines of Snellen visual acuity (VA) loss compared with preoperative VA, occurred in 63 of 247 eyes (25...

An 88-year-old woman with a history of complicated cataract extraction by phacoemulsification with sulcus intraocular lens (IOL) placement developed pseudophakic pupillary block after reverse implantation of the IOL. In the postoperative period, she had persistently elevated intraocular pressures (IOP) and was diagnosed with chronic angle-closure glaucoma that was treated medically. She presented 5 years later with acute pupillary block. The diagnosis of reverse IOL implantation was confirmed by ultrasound biomicroscopy...

AIM: To describe postoperative surgical success of either Ahmed or Baerveldt tube shunt implantation for eyes with medically uncontrolled traumatic glaucoma. MATERIALS AND METHODS: A review was carried out to identify patients with traumatic glaucoma that required tube shunt implantation between 2009 and 2015 at Rutgers University in Newark, New Jersey, USA.

AIM: To compare the intermediate-term efficacy of a large surface area Baerveldt 350 mm(2) glaucoma drainage device (GDD) with medium surface area implants (Baerveldt 250 mm(2) and Molteno 3, 230, or 245 mm(2)). DESIGN: This is a retrospective, nonrandomized comparative trial. MATERIALS AND METHODS: A total of 94 eyes of 94 patients of mixed glaucoma diagnoses without any prior glaucoma surgical procedures and who had undergone a glaucoma drainage implant surgery with either a large Baerveldt 350 mm(2) GDD or a medium-sized GDD (Baerveldt 250 mm(2) or Molteno 230 or 245 mm(2)) were reviewed for intraocular pressure (IOP), number of glaucoma medications, and visual acuity (VA) preoperatively, and at 1, 2, and 3 years postprocedure...

PURPOSE: To determine the relative efficacy of the Ahmed-FP7 and Baerveldt BG101-350 implants. DESIGN: Pooled analysis of 2 multicenter, randomized clinical trials. METHODS: A total of 514 patients aged 18 or older with uncontrolled glaucoma that had failed or were at high risk of failing trabeculectomy were randomized to receive an Ahmed implant (n = 267) or Baerveldt implant (n = 247). Cumulative failure rates (using an intraocular pressure [IOP] target of 6-18 mm Hg inclusive), de novo glaucoma surgery rates, mean IOP, mean glaucoma medication use, and visual acuity were compared...

PURPOSE OF THE STUDY: The purpose of the study was to report long-term outcomes and complications of Baerveldt glaucoma implant (BGI) surgery with pars plana tube insertion in children. MATERIALS AND METHODS: The medical records of consecutive aphakic and pseudophakic children (<16 y of age) who underwent BGI surgery with pars plana tube insertion between 1990 and 2013 were retrospectively reviewed. Main outcome measures were intraocular pressure and number of glaucoma medications...

PURPOSE: To date, there have only been 5 reported cases of orbital cellulitis following implantation of an aqueous tube shunt for glaucoma. Previously reported cases have involved eyes with significant comorbidities and successful management has often required the removal of the device alongside systemic antibiotic therapy. PATIENTS AND METHODS: We present a 53-year-old man with severe orbital cellulitis, 3 months after routine implantation of a Baerveldt tube shunt for primary open angle glaucoma...
