BackgroundThere is little information available about surgical management after failed glaucoma drainage device (GDD) surgery. We present the outcome of capsule excision after failed GDD surgery compared to capsule excision with additional use of a biodegradable implant (Ologen™, version 2) as a placeholder.MethodsIn an observational comparative case series of 19 patients undergoing excision of the GDD capsule, ten prospectively observed consecutive patients were treated by excision of the… Expand
Encapsulated Bleb Excision with Collagen Matrix Implantation Following Failed Ahmed Glaucoma Valve Implantation
TLDR
Encapsulated bleb excision with collagen matrix implantation resulted in a significant IOP-lowering effect 6 months after surgery, and fibrovascular ingrowth into the AGV was common but did not seem to be a major cause of AGV implantation failure. Expand
Failed glaucoma drainage implant: long-term outcomes of a second glaucoma drainage device versus cyclophotocoagulation
TLDR
After failure of an initial drainage implant to control IOP, a sequential tube had a high initial rate of success but a relatively high likelihood of long-term failure, generally after 6 years. Expand
Excisional Bleb Revision for Management of Failed Ahmed Glaucoma Valve
TLDR
Excisional bleb revision could be considered as a relatively effective alternative option for management of inadequate intraocular pressure control after AGV implantation. Expand
Tube Shunt Revision With Excision of Fibrotic Capsule Using Mitomycin C With and Without Ologen—a Collagen Matrix Implant: A 3-Year Follow-up Study
TLDR
Revision of a failed tube shunt by excision of the encapsulated bleb offers good medium-term outcomes by reducing the intraocular pressure and glaucoma medications. Expand
Tenon Cyst Patch Graft for Ahmed Glaucoma Valve Tube Exposure: Case Series Report
TLDR
The use of a Tenon's cyst autograft for the surgical repair of a tube exposure is valuable, as it involves using autologous scar tissue that is available in eyes that have undergone Ahmed Glaucoma Valve implantation. Expand
A Prospective Randomized Trial of Ahmed Glaucoma Drainage Device Implantation With or Without Ologen Collagen Matrix.
TLDR
OCM-augmented AGV surgery may provide better IOP control in the intermediate post-operative period, and blunt the hypertensive phase, compared to AGV implantation alone. Expand
Efficacy of Ologen matrix implant in Ahmed Glaucoma Valve Implantation
TLDR
Ologen does not increase safety or efficacy in Ahmed valve surgery at one-year follow-up and is the first study that shows no benefit of Ologen adjunctive to this surgery. Expand
Comparison of outcomes of trabeculectomy with mitomycin C vs. ologen implant in primary glaucoma
TLDR
The success of trabeculectomy and complications were similar in both Ologen and MMC groups at the end of 6 months, and the incidences of early post-operative complications weresimilar in the 2 groups. Expand
The use of collagen matrix (Ologen) as a patch graft in glaucoma tube shunt surgery, a retrospective chart review
TLDR
The results suggest that collagen matrix patch grafts may be used successfully as a patch graft in glaucoma tube shunt surgery, and may be advantageous because they do not have to be harvested from human donors. Expand
Improving Glaucoma Surgical Outcomes with Adjunct Tools
TLDR
The use of adjuncts, such as collagen matrix implants, fibrin adhesives, and amniotic membrane transplantation, have been found to be effective in modulating fibrosis and scarring during the wound-healing process, reducing postoperative inflammation, and repairing bleb leakage or conjunctival erosion.

Management of encapsulated blebs after glaucoma drainage device surgery
TLDR
Very good results are obtained using subconjunctival 5-FU injections, associated in complicated or refractory cases to needling revision, in eyes with encapsulated blebs after glaucoma drainage device surgery, with no major complications. Expand
Needling Revision of Glaucoma Drainage Device Filtering Blebs
TLDR
Needling revision can be useful in the management of poorly functioning GDD blebs, although the risk for severe complications exists. Expand
Baerveldt-350 Implant versus Ahmed Valve for Refractory Glaucoma: A Case-Controlled Comparison
TLDR
In a case-controlled comparison, the Baerveldt-350 implant and the Ahmed valve had similar IOP control and surgical outcomes in patients with refractory glaucoma at 1-year follow-up. Expand
Clinical experience with the Baerveldt 250-mm2 Glaucoma Implant.
TLDR
The Baerveldt 250-mm2 Glaucoma Implant provides good intermediate-term success for the treatment of adult refractory glaucomA. Expand
Aqueous shunt devices compared with trabeculectomy with Mitomycin-C for children in the first two years of life.
TLDR
Aqueous shunt implantation offers a significantly greater chance of successful glaucoma control in the first 2 years of life, compared with trabeculectomy with MMC, however, the enhanced success with aqueousShunt devices is associated with a higher likelihood of postoperative complications requiring surgical revision, most commonly tube repositioning. Expand
Efficacy of the Ahmed S2 glaucoma valve compared with the Baerveldt 250-mm2 glaucoma implant.
TLDR
The study suggests that the Ahmed S2 Glaucoma Valve may be less effective at lowering intraocular pressure than the Baerveldt 250-mm(2) GlAUcoma Implant. Expand
Shunt revision versus additional tube shunt implantation after failed tube shunt surgery in refractory glaucoma.
TLDR
It is shown that after failedtube shunt surgery, an additional tube shunt offers better intraocular pressure control than revision by excision of an encapsulated bleb. Expand
Ultrasound Biomicroscopy and Optical Coherence Tomography Imaging of Filtering Blebs after Deep Sclerectomy with New Collagen Implant
TLDR
UBM and OCT examinations are useful methods to evaluate outflow mechanisms after glaucoma surgery and deep sclerectomy with Ologen implantation seems to be an effective and well-tolerated method to reduce intraocular pressure. Expand
Intra-individual comparison after combined phaco-trabecular aspiration in pairs of pseudoexfoliative eyes
TLDR
The postoperative outcome in an eye after combined phaco-trabecular aspiration is predictive for the second eye and the prognosis for the same strategy in the fellow eye is also good. Expand
Control of filtering bleb structure through tissue bioengineering: An animal model.
TLDR
Implantation of a biodegradable, porous collagen matrix in the subconjunctival space offers the potential for a new means of avoiding early scar formation and maintaining long-term IOP control by creating a loosely structured filtering bleb. Expand
