We report a case of glaucoma implant tube lumen obstruction visualized with anterior segment optical coherence tomography (ASOCT) and present its surgical management. The patient was a 66-year-old man with refractory glaucoma associated with traumatic aphakia in the right eye after trabeculectomy, several bleb needling procedures, and scleral fixation of the intraocular lens with pars plana vitrectomy. Finally, we performed Baerveldt implantation at the pars plana of the temporal inferior quadrant with a several Sherwood slit...

We report the case of a 69-year-old female who underwent a Baerveldt implant placement for severe-stage primary open-angle glaucoma and developed a bacterial infection of the conjunctiva and abscess of the scleral patch graft with subsequent tube exposure. The infection was identified 3 weeks postoperatively and a topical antibiotic was immediately initiated. A concurrent systemic staphylococcal infection was discovered by an outside physician and oral cephalexin was initiated. Despite antibiotic treatment, the conjunctival erosion progressed, and tube revision was required...

AIM: To examine the efficacy and safety of Baerveldt tube (BT) implantation compared with combined phacoemulsification and Baerveldt tube (PBT) implantation in patients with refractory glaucoma. METHODS: Seventy-six eyes of 76 patients were enrolled, 38 pseudophakic eyes underwent BT implantation alone and 38 phakic eyes underwent the BT implantation combined with phacoemulsification. Groups were matched for preoperative intraocular pressure (IOP) and number of glaucoma medications...

PURPOSE: To describe and characterize a novel observation of intraluminal deposits of glaucoma tube shunts (TS) using spectral domain (SD) ocular coherence topography (OCT). PATIENTS AND METHODS: Fifteen TS in 11 patients diagnosed with primary open angle, neovascular, aphakic, and uveitic glaucomas. Both Ahmed (n=11) and Baerveldt (n=4) TS were examined with 5-line raster anterior segment SD-OCT imaging. RESULTS: The exposed tubes of two patients had highly reflective intraluminal deposits in the corresponding exposed areas...

PURPOSE: To describe a novel technique for tissue dissection during Baerveldt tube surgery. METHODS: We present a technique for posterior dissection of conjunctiva and Tenon tissue for the placement of a glaucoma drainage device. Hyaluronidase is used in the early stages of surgery in order to minimize tissue trauma and facilitate easy dissection even through existing adhesions and conjunctival scarring. RESULTS: The technique facilitates convenient dissection through tissues...

PURPOSE: To describe a venting stitch modification for valveless glaucoma aqueous shunts and characterize early postoperative intraocular pressure (IOP) and glaucoma medication use following the modification. MATERIALS AND METHODS: Retrospective chart review of 61 sequential patients undergoing Baerveldt Glaucoma Implant (BGI)-350 implantation at the Doheny Eye Institute. Twenty four patients received a glaucoma shunt with venting stitch modification (modified BGI) and 37 patients received an unmodified shunt (BGI-only)...

PURPOSE: To apply propensity score matching to compare Baerveldt glaucoma drainage implant (BGI) to Trabectome-mediated ab interno trabeculectomy (AIT). Recent data suggests that AIT can produce results similar to BGI which is traditionally reserved for more severe glaucoma. METHODS: BGI and AIT patients with at least 1 year of follow-up were included. The primary outcome measures were intraocular pressure (IOP), number of glaucoma medications, and a Glaucoma Index (GI) score...

PURPOSE: To evaluate long-term outcomes on efficacy and safety of severe uveitic glaucoma treated with a Baerveldt glaucoma implant (BGI). METHODS: A retrospective study of 47 eyes of 47 patients with uveitic glaucoma treated by a BGI between September 2002 and September 2015. Main outcome measures were intraocular pressure (IOP), number of glaucoma medications, course of the uveitis, visual acuity (VA) and complications. RESULTS: Mean IOP dropped from 30...

We evaluated bleb fluid images taken after Baerveldt glaucoma implantation. T2-weighted images of bleb fluid were scanned with 3 Tesla magnetic resonance imaging in 52 patients who had undergone tube-shunt surgery using the 350-mm(2) endplate Baerveldt glaucoma implant; three-dimensional images were constructed from these images. Bleb fluid images were classified into either a layer of bleb fluid on either side of the endplate (double bleb layer group; n = 24) or one layer outside the endplate (single bleb layer group; n = 28)...

PURPOSE: Evaluate factors contributing to ptosis after glaucoma surgery. METHODS: Three-year retrospective chart review from January 1, 2012, to January 1, 2015, 157 eyes, 3 surgeons, at Boston Medical Center, to determine the incidence of ptosis and the effects of each variable contributing to ptosis at 3 months after surgery. Each variable was analyzed using the chi-square or independent samples t-test analysis to determine statistical significance of ptosis compared with above variables...

BACKGROUND: Aqueous shunts are employed to control intraocular pressure (IOP) for people with primary or secondary glaucomas who fail or are not candidates for standard surgery. OBJECTIVES: To assess the effectiveness and safety of aqueous shunts for reducing IOP in glaucoma compared with standard surgery, another type of aqueous shunt, or modification to the aqueous shunt procedure. SEARCH METHODS: We searched CENTRAL (which contains the Cochrane Eyes and Vision Trials Register) (2016, Issue 8), MEDLINE Ovid (1946 to August 2016), Embase...

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...
