“…We found a success rate of 86.4% with at least 1 year of follow-up. Our results support the findings of a previous prospective study, 11 which reported a rate of success of 86% during a 6-month followup period.…”

“…The absence of early postoperative complications in our study could be partially because of the fact that all surgeries were done by one experienced surgeon in long-tube glaucoma implant surgery. In addition, one previous prospective study with multiple well-trained surgeons investigating the SGDD implant also found low rates of early complications (5.2%) 11…”

“…In this study, no motility disorder was reported. However, Biteli et al 11 found a 9% rate of motility disorders with the SGDD, although they were all transient and did not require further treatment. Because of its size and placement beneath 2 adjacent rectus muscles, 36 motility problems with the Baerveldt 350 shunt have been reported to vary between 3% and 18%.…”

“…In addition, one previous prospective study with multiple welltrained surgeons investigating the SGDD implant also found low rates of early complications (5.2%). 11 There was only 1 case (4.5%) of late hypotony that resolved with tube ligature (silk 8-0) in a patient that had previously undergone endocyclodesctructive procedure, which could predispose to hypotony. 30,31 In this case, IOP remained low with no medications after tube ligature, probably because of ciliary body failure.…”

“…One previous study investigating Susanna implant safety showed low rates of serious complications, with 2 cases of conjunctival erosion (3.44%) and 2 cases of late hypotony (3.44%). 11 Although promising results, this study had a relatively short-term follow-up (7.1 ± 3.8 mo) and long-term data is still not available in the literature.…”

Precis: This study found a rate of failure of 13.6% of the new Susanna Glaucoma Drainage Device (SGDD) after 1 year of follow-up. Severe complications occurred in 1 patient (4.5%). Purpose:The purpose of this study was to determine the success and complications rates of the SGDD implant in refractory glaucoma.Patients and Methods: This is a retrospective study. Medical records from all consecutive refractory glaucoma patients (failed trabeculectomies with the use of adjunctive mitomycin) followed in a private clinical practice were included in the study. All patients had undergone SGDD implant surgery from September 2016 to July 2019 were included. All surgeries were done by the same surgeon (R.S.). Primary outcome was surgical failure, defined as intraocular pressure (IOP) > 18 mm Hg and/or < 20% IOP reduction from baseline, IOP < 5 mm Hg, reoperation for glaucoma, need of implant removal or loss of light perception vision. Secondary outcomes included mean IOP, use of supplemental medical therapy, and complications.Results: In all, 22 eyes were analyzed. Mean patient age was 63 ± 15 years (range: 27 to 87 y). Mean IOP decreased from 23 ± 7 to 11 ± 8 mm Hg (P < 0.001, paired t test) at an average of 18 ± 9 months after the tube implant. The mean SD number of glaucoma medications was reduced from 3.3 ± 1 to 1.5 ± 1.2 at the last postoperative visit (P < 0.01, paired t test). No early postoperative complications occurred. There was 1 case of late persistent hypotony in a patient with previous endocyclophotocoagulation that was solved with tube ligature with silk 8-0. Failure because of high IOP occurred in 2 cases. There was no extrusion or erosion of the tube and the plate. Conclusion:The SGDD presented a 13.6% failure rate (86.4% success rate) with very few complications, being an efficient and safe alternative for refractory glaucoma.

Glaucoma drainage devices are important therapeutic options for cases of refractory glaucoma, in which trabeculectomy with antimetabolites has shown high risk of failure. There are devices with different sizes, designs and materials, and several studies have been conducted to test their safety and effectiveness. Despite known complications, their use has progressively increased in recent years, and they are the primary surgical option, in some situations. The aim of this review is to discuss the importance, mechanisms, biomaterials, results and complications of glaucoma drainage devices. RESUMOOs dispositivos de drenagem para glaucoma são importante opção terapêutica em casos de glaucomas refratários, nos quais a trabeculectomia com antimetabólitos tem alta chance de falência. Há dispositivos com diferentes tamanhos, desenhos e materiais, e muitos estudos foram realizados para testar sua segurança e eficácia. Apesar de suas conhecidas complicações, seu uso tem aumentado progressivamente nos últimos anos, inclusive como primeira opção cirúrgica, em algumas situações. O objetivo desta revisão foi discutir a importância, os mecanismos, os biomateriais, os resultados e as complicações dos dispositivos de drenagem para glaucoma.
