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. Culture of the abscess revealed coagulase-negative Staphylococcus. As alluded to above, the patient also had multiple abscesses on the skin that cultured positive for Staphylococcus aureus. To our knowledge, this is the first case in the literature of coagulase-negative Staphylococcus causing an early postoperative abscess of the scleral patch graft following glaucoma drainage device placement.

Purpose. Refractory glaucoma patients continue to require surgical intervention in the form of trabeculectomy surgery or glaucoma drainage device (GDD). Those patients that require a GDD but have thin sclera or scleromalacia present a challenge. Methods. In this article, we present a novel “TAG sandwich” single surgical procedure in which thinned sclera is reinforced with a pericardial patch graft (“bottom layer of the sandwich”) allowing safe implantation of the GDD (“the tube sandwich filling”) and then placing another patch graft on top of the tube part of the GDD (“top layer of the sandwich”). The surgery was performed on an open-angle glaucoma patient with a generalized thin sclera and uncontrolled intraocular pressure despite maximal topical medication and oral acetazolamide. Results. Reinforcing a compromised sclera with a pericardium patch graft allowed the safe implantation of a glaucoma drainage device. The patient’s intraocular pressure was safely controlled at 7 mmHg almost 1-year postsurgery without intraocular pressure-lowering drops. Conclusions. This scleral strengthening procedure can be considered by readers in other ocular surgeries where there is a risk of scleral perforation, as well as part of a combined surgery where refractory glaucoma patients with thin sclera require scleral reinforcement to allow for safer implantation of a glaucoma drainage device.

Purpose. To report a new technique for anterior placement of tubes for glaucoma drainage devices to reduce the risk of tube erosions.Methods. Retrospective review of select cases of Ahmed Valve surgery combined with the novel method of a limbal-based scleral flap covered by a scleral patch graft to cover the tube at the entrance through the limbus. Intraoperative and postoperative illustrations are shown to highlight the method of tube placement.Results. In this retrospective case series, 3 patients are presented illustrating the technique. Two had neovascular glaucoma and one had primary open-angle glaucoma (POAG). On average, intraocular pressure was reduced from39±14 mmHg to15±2 mmHg and the number of glaucoma medications was reduced from4±1to 0. Preoperative and most recent visual acuities were hand-motion (HM) and HM, 20/60 and 20/50, and 20/70 and 20/30, respectively.Conclusion. The combination of a limbal-based scleral flap with scleral patch graft to cover the tube with glaucoma drainage devices may be an effective means to reduce erosion and protect against endophthalmitis.
