RESUMO
PRCIS: This retrospective case series of patients with open angle glaucoma and prior trabeculectomy or tube shunt surgery found that selective laser trabeculoplasty (SLT) resulted in significant intraocular pressure (IOP) reductions in the intermediate follow-up period in select cases. PURPOSE: The purpose of this study was to assess the IOP-lowering effect and tolerability of SLT after prior trabeculectomy or tube shunt surgery. MATERIALS AND METHODS: Open angle glaucoma patients at Wills Eye Hospital who previously underwent incisional glaucoma surgery and subsequently received SLT between 2013 and 2018 were included, along with an age-matched control group. Baseline characteristics, procedural data, and post-SLT data were recorded at 1, 3, 6, 12 months, and most recent visit. The primary success of SLT treatment was defined as IOP reduction of 20% or greater without the use of additional glaucoma medications compared to pre-SLT IOP. Secondary success was defined as IOP reduction ≥20% with the use of additional glaucoma medications compared to pre-SLT IOP. RESULTS: There were 45 eyes in the study group and 45 eyes in the control group. In the study group, IOP decreased from a baseline of 19.5±4.7 mm Hg on 2.2±1.2 medications to 16.7±5.2 mm Hg ( P =0.002) on 2.2±1.1 glaucoma medications ( P =0.57). In the control group, IOP decreased from 19.5±4.2 mm Hg on 2.4±1.0 medications to 16.4±5.2 mm Hg ( P =0.003) on 2.1±1.3 medications ( P =0.36). There was no difference in IOP reduction or change in number of glaucoma medications after SLT at any postoperative visit between the 2 groups ( P ≥0.12 for all). Primary success rates at 12 months were 24.4% for the control group and 26.7% for the prior incisional glaucoma surgery group with no significant difference between the groups ( P =0.92). There were no persistent complications after SLT treatment in either group. CONCLUSION: SLT may effectively lower IOP in patients with open angle glaucoma who have had previous incisional glaucoma surgery and should be considered in select cases.

PURPOSE: Late hypotony is an undesirable and challenging complication of glaucoma surgery. We describe our use of the Ologen Collagen Matrix to treat late hypotony developing after trabeculectomy. STUDY DESIGN: A retrospective study performed at three eye surgery centers in Brazil. PARTICIPANTS: Eighteen patients who underwent 19 eye surgeries. INTERVENTION: Subconjunctival Ologen was implanted at the trabeculectomy sites to treat over-filtering or leaking blebs in patients experiencing late hypotony after trabeculectomy (obtained 6 months after glaucoma surgery). The primary outcome was the intraocular pressure (IOP); we gathered preoperative data records from 19 Ologen treated eyes and days 1, 7, 30, 60, and 180 postoperatively. The secondary outcomes included visual acuity and macular thickness measured via optical coherence tomography; we compared preoperative data to subsequent ones up to sixth-month-evolution. RESULTS: Over the 6-month period, the IOP rose from 2.89 ± 1.59 mmHg preoperatively to 8.21 ± 3.46 mmHg (p = 0.0001). Visual acuity improved from 0.33 ± 0.29 to 0.21 ± 0.31 LogMar (p = 0.0013). Macular thickness fell from 325.62 ± 58.7 to 283.08 ± 47.35 µm (p = 0.0097). We encountered two complications: one related to suture dehiscence following an ocular trauma and one instance of transitory choroidal detachment. CONCLUSION: Subconjunctival Ologen implants preserved bleb function and successfully treated post-trabeculectomy hypotony as revealed by data collected at the 6-month follow-up. Longer follow-up is necessary to confirm long-term efficacy and safety. There are no financial conflicts of interest to disclose.

PURPOSE: The purpose of this study was to investigate the postoperative outcomes and evaluate the success predictors of phacoemulsification with Kahook Dual Blade goniotomy for cataract and glaucoma management in eyes with primary open-angle glaucoma. METHODS: This was a retrospective, non-comparative; inter ventional case series in which all patients with primary open-angle glaucoma who underwent phacoemulsification with Kahook Dual Blade goniotomy between June 2018 and April 2019 were enrolled. All the participants had a minimum follow-up period of 6 months. Preoperative and postoperative intraocular pressure values (at 1, 3, and 6 months), number of antiglaucoma medications, best-corrected visual acuity, surgical complications, and any subsequent related events or procedures were recorded. A logistic regression analysis was performed to investigate the association between the different variables and surgical outcomes. RESULTS: A total of 47 patients (57 eyes) were included (mean age, 70.5 ± 7 years). The mean intraocular pressure was reduced from 15.5 ± 4.2 mmHg to 12.2 ± 2.4 mmHg at the last follow-up visit (p<0.001). The mean number of antiglaucoma medications decreased significantly from 1.9 ± 1.0 to 0.6 ± 1.0 during the same period (p<0.001). On the basis of the predefined criterion (intraocular pressure reduction ≥20% and/or reduction ≥1 medication), the 6-month success rate was 86%. A higher preoperative intraocular pressure value (odds ratio [OR]= 2.01; p=0.016) and greater percentage of initial (30 days) intraocular pressure reduction (OR= 1.02; p=0.033) were sig nificantly associated with surgical success. CONCLUSION: Our findings suggest that phacoemulsification with Kahook Dual Blade goniotomy is an effective and safe alternative for cataract management in eyes with primary open-angle glaucoma that positively impacts intraocular pressure control and medication burden. Eyes with higher baseline intraocular pressure and a more pronounced initial response to the procedure appeared to present better outcomes at 6 months. Further studies are needed to evaluate the long-term efficacy and safety profile of the procedure.

PURPOSE:: The aim of this study was to introduce a reproducible algorithm for the surgical management of late-onset (>2 months) bleb complications after trabeculectomy with mitomycin C. METHODS:: We performed a retrospective review of eyes treated using a reproducible algorithm approach by a single surgeon for the surgical management of late-onset bleb complications from July 2006 to April 2014. Exclusion criteria were bleb revision with less than 3 months of follow-up or bleb revision combined with other glaucoma procedures at the time of surgery. Success was evaluated using the Kaplan-Meier survival method and defined as achieving all of the following criteria: primary surgery indication resolved, no additional surgery required for decreasing the intraocular pressure (IOP), and IOP of ≥6 mmHg and ≤18 mmHg. RESULTS:: Twenty-three eyes from 20 patients were evaluated. Indications for bleb revision were hypotonic maculopathy (47.8%), bleb leak (30.4%), and dysesthetic bleb (21.7%). The overall primary outcome success rate calculated using the Kaplan-Meier survival method was 65.2% at 48 months. When the IOP target was changed to ≤15 mmHg, the bleb survival rate was 47.8% at 48 months. At the most recent postoperative visit, 95.7% of eyes had an IOP of ≤15 mmHg and 56.5% were being treated with an average of one medication per eye. One eye (4.3%) required a second bleb revision for persistent hypotony and two eyes required glaucoma surgery to reduce IOP during follow-up. CONCLUSIONS:: An algorithm approach for the surgical management of late-onset bleb complications with a success rate similar to those reported in specialized literature is proposed. Randomized trials are needed to confirm the best surgical approach.

RESUMO Objetivo: Descrever um algoritmo reprodutível para o tratamento cirúrgico das complicações da bolha de início tardio (>2 meses) após trabeculectomia com mitomicina-C. Métodos: Revisão retrospectiva de olhos que foram submetidos a um algoritmo reprodutível para o tratamento cirúrgico das complicações da bolha de início tardio por um único cirurgião, de julho de 2006 a abril de 2014. Os critérios de exclusão foram revisão de bolha com menos de 3 meses de seguimento ou revisão de bolha combinado com outro procedimento antiglaucomatoso no momento da cirurgia. O sucesso foi avaliado pelo método de sobrevida de Kaplan-Meier e definidos como ter atingido todos os seguintes critérios: indicação de cirurgia primária resolvido, nenhuma cirurgia adicional necessária para diminuir a pressão intraocular (IOP), IOP ≥6 mmHg e ≤18 mmHg. Resultados: Vinte e três olhos de 20 pacientes foram incluídos. Indicações para revisão bolha foram maculopatia hipotônica (47,8%), extravasamento da bolha (30,4%) e bolha elevada (21,7%). A taxa de sucesso do resultado primário global calculada pelo método de sobrevivência de Kaplan-Meier foi de 65,2% aos 48 meses. Quando a IOP foi diminuída para ≤15mmHg, a taxa de sobrevivência bolha foi de 47,8% em 48 meses. Na visita pós-operatória mais recente, 95,7% dos olhos apresentavam PIO ≤15mmHg e 56,5% estavam sob tratamento com uma média de um medicamento por olho. Um olho (4,3%) necessitou de uma segunda revisão da bolha para hipotonia persistente e dois olhos necessitaram cirurgia de antiglaucomatosa para reduzir a IOP durante o seguimento. Conclusões: Um algoritmo de abordagem para o tratamento cirúrgico das complicações tardias da bolha com uma taxa de sucesso semelhante aos relatados na literatura especializada é proposto. Ensaios clínicos randomizados são necessários para confirmar a melhor abordagem cirúrgica.

PURPOSE: To describe the outcomes of eyes that have undergone a second glaucoma drainage implant (GDI) surgery. METHODS: A retrospective review of eyes that underwent a second GDI surgery from 2006 to 2013 was conducted. Primary outcome measures included intraocular pressure (IOP) reduction and success rates. Secondary outcome measures included glaucoma medication use, visual acuity, and number of reoperations. Success was defined as 6 ≤ IOP ≤ 21 with at least 20% IOP reduction, and no increase in the number of glaucoma medications from baseline at 3 months of follow-up or more. RESULTS: Sixty-five eyes (63 patients) had a mean follow-up of 22.4 ± 19.9 months. The most frequently placed second GDIs were an Ahmed FP7 (49%) or a Baerveldt 250 (26%) in the inferotemporal (46%) or inferonasal (35%) quadrant. At 3-year follow-up, IOP was reduced from 25.8 ± 7.7 to 17.4 ± 9.9 mm Hg (P = 0.004) and the number of glaucoma medications decreased from 3.6 ± 1.2 to 2.5 ± 1.4 (P = 0.01) compared with baseline. The median time to failure was 24.7 ± 5.8 months. There was no significant difference in failure rates for type of sequential GDI (P = 0.80) or plate location (P = 0.34). There was no significant difference in visual acuity between baseline and 3-year follow-up (P = 1.0). The most common postoperative complication was corneal edema (n = 9, 14%). CONCLUSIONS: Most eyes undergoing a second GDI achieve adequate IOP control with fewer antiglaucoma medications. Failure rates were similar regardless of quadrant selection or GDI type.

Cyclodialysis is a relatively rare condition usually caused by ocular injury; however, it can also be caused iatrogenically during intraocular surgery. Hypotony maculopathy is the most important complication and the primary reason for visual loss. Clinical diagnosis using gonioscopy may be difficult, and ultrasound biomicroscopy (UBM) can be an alternative. There are different kinds of treatments, and the optimal one remains controversial. Here we describe a case of traumatic cyclodialysis with persistent ocular hypotony treated by direct cyclopexy, as illustrated by UBM performed before and after surgery.

PURPOSE: To describe a modified suturing technique for the treatment of hypotony. METHODS: A prospective case series of 15 patients with hypotony from an overfiltering trabeculectomy underwent full-thickness hypotony sutures. The technique involves placing several radial interrupted 10-0 nylon sutures in the area of the prior trabeculectomy. The suture pass starts at the limbus, travels through the conjunctiva, and full-thickness sclera before exiting the conjunctiva. The sutures were selectively removed postoperatively to titrate the intraocular pressure (IOP). Hypotony resolution, IOP, visual acuity, and complications were assessed on postoperative visits. RESULTS: Before surgery, the mean IOP was 3.3 mm Hg. The mean IOP 1 day after surgery was 23.5 mm Hg, which settled to 12.9 mm Hg 3 months after surgery. Hypotony was reversed in 100% of patients and 87% achieved a goal IOP. Suture removal was performed in 73%, most within the first week after surgery. CONCLUSIONS: Placing full-thickness hypotony sutures is an effective way to treat ocular hypotony. Sutures can be removed postoperatively to titrate the IOP.

Ciclodiálise é uma condição relativamente rara, geralmente devido a um trauma ocular, mas também pode ser causada iatrogenicamente como consequência de cirurgia intraocular. A maculopatia hipotônica é a complicação mais importante e a principal razão para a perda visual nessa situação. O diagnóstico clínico por gonioscopia pode ser difícil e a biomicroscopia ultrassônica (UBM) pode ser uma alternativa. Existem diferentes tipos de tratamentos e algumas controvérsias sobre a melhor opção. Neste relato, nós descrevemos um caso de ciclodiálise traumática com hipotonia ocular persistente tratado por cyclopexia direta avaliado por UBM antes e depois da cirurgia.

PURPOSE: To report on a new treatment for hyperfiltering bleb as well as its diagnostic criteria. METHODS: Twenty eyes with hypotony due to hyperfiltering bleb caused by trabeculectomy with mitomicin C were treated with bleb resection. The diagnosis of hyperfiltering bleb followed these criteria: intraocular pressure lower than six mmHg (Goldmann tonometer); no inflammation in the anterior segment; presence of an elevated and/or diffuse and avascular bleb with or without microcysts; negative Seidel test; no ciliochoroidal detachment found with ultrasound biomicroscopy. We registered the following data pre and post operatively: type of glaucoma, visual acuity, bleb aspect and fundoscopic findings. A successful resolution of hypotony was achieved when intraocular pressure ranged from six to 14 mmHg with or without antiglaucomatous medication. RESULTS: At a minimum follow-up of 19 months ocular hypotony had been reversed in all eyes. At the last exam, intraocular pressure varied from eight to 14 mmHg in 18 (90 percent) eyes; 12 (66.7 percent) eyes had no medication and six (33.3 percent) used antiglaucomatous medication. In two (10 percent) eyes, another trabeculectomy was necessary to control intraocular pressure. Hypotonic maculopathy developed preoperatively in seven eyes and was reversed after bleb resection. Visual acuity improved in 15 (75 percent) eyes but did not change in five (25 percent). CONCLUSION: Bleb resection is a safe and adequate treatment for ocular hypotony due to hyperfiltering bleb. It also restores vision in a considerable number of patients. The diagnosis of hyperfiltering bleb must follow rigorous criteria.
OBJETIVO: Relatar os resultados de uma nova técnica para o tratamento de bolsa hiperfuncionante, assim como seus critérios diagnósticos. MÉTODOS: Vinte olhos (20 pacientes) com hipotonia ocular causada por bolsa hiperfuncionante após trabeculectomia com mitomicina C foram tratados com ressecção da bolsa. O diagnóstico de bolsa hiperfuncionante obedeceu aos seguintes critérios: pressão intraocular inferior a seis mmHg (tonometria de Goldmann); ausência de inflamação do segmento anterior ocular; presença de bolsa fistulante elevada e/ou difusa e avascular com ou sem microcistos; teste de Seidel negativo; ausência de descolamento ciliocoroidiano ao exame de UBM. Foram registrados no pré e pós-operatório: o tipo de glaucoma, a acuidade visual, o aspecto da bolsa e os achados oftalmoscópicos. A resolução da hipotonia foi alcançada quando a pressão intraocular variou de seis a 14 mmHg sem ou sob medicação tópica antiglaucomatosa. RESULTADOS: No seguimento mínimo de 19 meses, a hipotonia ocular foi revertida nos 20 olhos. No último exame, a pressão intraocular variou de oito a 14 mmHg em 18 (90 por cento) olhos; 12 (66,7 por cento) olhos sem medicação e seis (33,3 por cento) olhos sob medicação tópica. Em dois (20 por cento) olhos foi necessário nova trabeculetomia para controle da pressão intraocular. Maculopatia hipotônica foi diagnosticada no pré-operatório em sete olhos e foi revertida em todos eles após a ressecção da bolsa. A acuidade visual melhorou em 15 (75 por cento) olhos e não se alterou em cinco (25 por cento). CONCLUSÃO: A ressecção da bolsa é eficaz no tratamento da hipotonia ocular consequente a sua hiperfunção. Esse procedimento também recupera a visão num considerável número de pacientes. O diagnóstico de bolsa hiperfuncionante deve obedecer a critérios rigorosos.

Objetivo: Relatar um caso de hipotonia ocular após trabeculectomia em que se realizou sutura de compressão sobre a bolha hiperfiltrante e obtendo-se controle da pressão intra-ocular. Local: Departamento de Glaucoma da Fundação Altino Ventura, Recife - PE. Método: Relato do caso. Resultado: O método da sutura de compressão determinou uma remodelação da bolha hiperfiltrante e controle da pressão intra-ocular. Conclusão: Apesar de o paciente não apresentar melhora da acuidade visual, provavelmente pelos aspectos clínicos pré-operatórios do glaucoma, a pressão intra-ocular sofreu um aumento clinicamente significante, o que sugere ser a sutura de compressão uma opção de tratamento para bolhas hiperfiltrantes.
