RESUMEN
PURPOSE: To compare postoperative changes in retinal nerve fiber layer thickness in patients with macular holes treated with vitrectomy with Brilliant Blue-assisted internal limiting membrane peeling. METHODS: Twenty-two eyes of 20 patients with macular holes were studied. Each eye was selected to undergo Brilliant Blue-assisted internal limiting membrane peeling. The circumferential retinal nerve fiber layer thickness was determined using spectral domain optical coherence tomography preoperatively and 2 months postoperatively. Mean overall and sectoral retinal nerve fiber layer thicknesses were obtained for each patient. RESULTS: There was no statistically significant difference (p≥0.05) between the pre- and post-treatment measurements in relation to each CFN variable, i.e., on average, pre-treatment measures were the same as post-treatment measures. Furthermore, despite the differences between the pre- and post-treatment measures always being positive (pre-post >0), they are not statistically significant. CONCLUSIONS: This study showed no significant decrease in retinal nerve fiber layer thickness measurements after macular holes surgery, regardless of age or sex.

RESUMO Objetivo: Comparar as alterações pós-operatórias na espessura da camada de fibras nervosas da retina em pacientes com buracos maculares submetidos à vitrectomia via pars-plana associada à remoção de membrana limitante interna. Métodos: Foram estudados 22 olhos de 20 pacientes consecutivos diagnosticados com buraco macular. Todos os pacientes foram submetidos à vitrectomia via pars-plana e remoção de membrana limitante interna corada com azul brilhante. A espessura da camada de fibras nervosas da retina em região peripapilar foi determinada por tomografia de coerência óptica de domínio espectral antes e 2 meses após a cirurgia. As espessuras totais e espessuras setoriais da camada de fibras nervosas da retina foram obtidas para cada paciente. Resultados: Os resultados mostram que não existe diferença estatisticamente significativa (p≥0,05) entre as medidas pré e pós-operatórias em relação a cada uma das variáveis. Conclusão: Este estudo não demonstrou diminuição significativa nas medidas da espessura da camada de fibras nervosas retinianas após a cirurgia de buraco macular, independente da faixa etária ou sexo.
