Abstract

Varíola do Macaco é uma zoonose viral com sintomas semelhantes aos observados no passado em pacientes com Varíola, embora seja clinicamente menos grave. Com a erradicação da varíola em 1980 e a subsequente cessação da vacinação contra a varíola, a varíola dos macacos emergiu como o ortopoxvírus mais importante em saúde pública. O vírus monkeypox ocorre principalmente na África central e ocidental, muitas vezes nas proximidades de florestas tropicais, e tem se manifestado cada vez mais em áreas urbanas. Os hospedeiros animais incluem uma variedade de roedores e primatas não humanos. O presente estudo relata o caso de um paciente com Monkeypox que evoluiu com queixa oftalmológica de desconforto ocular e conjuntivite e, à biomicroscopia e teste da fluoresceína, detecção de lesões conjuntivais. Alterações oftalmológicas da doença são, ainda, pouco conhecidas.

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.
