Abstract

OBJETIVO: Investigar e descrever, entre os membros da Sociedade Brasileira de Glaucoma (SBG), as práticas relativas ao manejo de anticoagulantes (varfarina e aspirina) em pacientes agendados para cirurgia antiglaucomatosa. MÉTODOS: Foi enviado um questionário objetivo aos membros ativos da Sociedade Brasileira de Glaucoma avaliando diferentes aspectos da forma como conduzem seus pacientes em uso de varfarina ou aspirina durante o período perioperatório de uma cirurgia antiglaucomatosa. RESULTADOS: Cinquenta e dois participantes retornaram o questionário preenchido adequadamente. O uso de varfarina ou aspirina foi rotineiramente interrompido antes da cirurgia antiglaucomatosa por 82,7% dos entrevistados. A maior parte dos cirurgiões, quando interromperam o uso destes medicamentos, o fez sete dias antes da cirurgia e os reintroduziram no dia seguinte ao procedimento. Aproximadamente metade dos entrevistados disse ter observado complicações hemorrágicas que poderiam ser relacionados à terapia anticoagulante. Embora a maioria dos cirurgiões (86,5%) referiu utilizar alguma técnica cirúrgica em particular para esses pacientes anticoagulados, quase todos (88,5%) não alteram seu planejamento anestésico de rotina nesses mesmos casos. Finalmente, a maior parte dos participantes (90,4%) relatou referir seus pacientes anticoagulados para uma avaliação pré-operatória com um cardiologista ou um clínico geral. CONCLUSÃO: A maior parte dos membros da Sociedade Brasileira de Glaucoma que participou desse estudo refere interromper o uso de anticoagulantes (varfarina ou aspirina) antes de uma cirurgia antiglaucomatosa. Embora existam poucas informações disponíveis na literatura para oferecer uma orientação definitiva, a maioria dos participantes parece compartilhar da mesma opinião quando se trata do manejo perioperatório de anticoagulantes.

Abstract

PURPOSE: This study aimed to compare the safety and effectiveness of intraocular pressure reduction between micropulse transscleral cyclophotocoagulation and “slow cook” transscleral cyclophotocoagulation in patients with refractory primary open-angle glaucoma.
METHODS: We included patients with primary open angle glaucoma with at least 12 months of follow-up. We collected and analyzed data on the preoperative characteristics and postoperative outcomes. The primary outcomes were a reduction of ≥20% of the baseline value (criterion A) and/or intraocular pressure between 6 and 21 mmHg (criterion B).
RESULTS: We included 128 eyes with primary open-angle glaucoma. The preoperative mean intraocular pressure was 25.53 ± 6.40 and 35.02 ± 12.57 mmHg in the micropulse- and “slow cook” transscleral cyclophotocoagulation groups, respectively (p<0.001). The mean intraocular pressure was reduced significantly to 14.33 ± 3.40 and 15.37 ± 5.85 mmHg in the micropulse- and “slow cook” transscleral cyclophotocoagulation groups at the last follow-up, respectively (p=0.110). The mean intraocular pressure reduction at 12 months was 11.20 ± 11.46 and 19.65 ± 13.22 mmHg in the micropulse- and “slow cook” transscleral cyclophotocoagulation groups, respectively (p<0.001). The median preoperative logMAR visual acuity was 0.52 ± 0.69 and 1.75 ± 1.04 in the micropulse- and “slow cook” transscleral cyclophotocoagulation groups, respectively (p<0.001). The mean visual acuity variation was -0.10 ± 0.35 and -0.074 ± 0.16 in the micropulse- and “slow cook” transscleral cyclophotocoagulation, respectively (p=0.510). Preoperatively, the mean eye drops were 3.44 ± 1.38 and 2.89 ± 0.68 drugs in the micropulse- and “slow cook” transscleral cyclophotocoagulation groups, respectively (p=0.017), but those were 2.06 ± 1.42 and 1.02 ± 1.46 at the end of the study in the slow cook” and micropulse transscleral cyclophotocoagulation groups, respectively (p<0.001). The success of criterion A was not significant between both groups. Compared with 11 eyes (17.74%) in the slow cook” transscleral cyclophotocoagulation group, 19 eyes (28.78%) in the micropulse transscleral cyclophotocoagulation group showed complete success (p=0.171). For criterion B, 28 (42.42%) and 2 eyes (3.22%) showed complete success after micropulse- and slow cook” transscleral cyclophotocoagulation, respectively (p<0.001).
CONCLUSION: Both techniques reduced intraocular pressure effectively.

Abstract

PURPOSE: To compare the efficacy and safety of trabeculectomy with mitomycin C, performed with versus without adjunctive Ologen collagen matrix in a multicenter real-world setting.
METHODS: This multicenter retrospective comparative study included 277 patients (365 eyes) who underwent trabeculectomy with mitomycin C, with or without Ologen, between 2017 and 2022 across five Brazilian centers. Extracted data comprised demographic characteristics, glaucoma subtype, intraocular pressure, number of glaucoma medications, postoperative interventions, complications, and additional surgical procedures. Surgical success was defined using two criteria: (1) intraocular pressure ≤21mmHg with ≥20% reduction from baseline and (2) final intraocular pressure between 6 and 21mmHg. Outcomes were categorized as complete (without medications) or qualified (with medications).
RESULTS: Both groups achieved substantial reductions in intraocular pressure and medication burden at 12 months, with high rates of complete and qualified success under both definitions. The Ologen group required fewer suture lysis procedures (49.0% vs. 60.8%; p=0.025), suggesting a modulatory effect on early postoperative fibrosis. Rates of other postoperative interventions, complications, and additional glaucoma surgeries were comparable between groups. Kaplan–Meier analysis demonstrated no significant difference in cumulative success over time.
CONCLUSION: Trabeculectomy with mitomycin C is effective and safe regardless of adjunctive Ologen use. Although Ologen did not confer superior long-term efficacy, its association with reduced suture lysis suggests a potential role in modulating early wound healing.
