Abstract
in English, Spanish

Introduction: Trabeculectomy is considered the standard for glaucoma surgery. Postoperative scarring is one the factors associated with surgery failure. Different antimetabolites have been used in order to reduce this risk, particularly 5-fluorouracil and mitomycin C. Although both are considered effective, it is not clear if they are different in terms of success of trabeculectomy and adverse effects.

Methods: To answer this question we used Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others. We extracted data from the systematic reviews, reanalyzed data of primary studies, conducted a meta-analysis and generated a summary of findings table using the GRADE approach.

Results and conclusions: We identified four systematic reviews including 17 studies overall, of which 12 were randomized trials. We concluded mitomycin C might be more effective in reducing intraocular pressure and increasing qualified success compared to 5-fluorouracil. However, its use might be associated to a higher risk of complications.

Introducción: La trabeculectomía es considerada la intervención de elección en pacientes con glaucoma con indicación de manejo quirúrgico. Dentro de los factores asociados al fracaso de este tratamiento se encuentra la cicatrización postoperatoria. Para disminuir este factor se han usado distintos antimetabolitos, en particular el 5-fluorouracilo y la mitomicina C. Si bien ambos se consideran efectivos, no está claro si existen diferencias entre ambos en relación al éxito de la trabeculectomía y los efectos adversos.

Métodos: Para responder esta pregunta utilizamos Epistemonikos, la mayor base de datos de revisiones sistemáticas en salud, la cual es mantenida mediante búsquedas en múltiples fuentes de información, incluyendo MEDLINE, EMBASE, Cochrane, entre otras. Extrajimos los datos desde las revisiones identificadas, reanalizamos los datos de los estudios primarios, realizamos un metanálisis, preparamos tablas de resumen de los resultados utilizando el método GRADE.

Resultados y conclusiones: Identificamos cuatro revisiones sistemáticas que en conjunto incluyen 17 estudios primarios, de los cuales, 12 corresponden a ensayos aleatorizados. Concluimos que el uso de mitomicina C podría lograr una mayor disminución de la presión intraocular e incrementar la tasa de éxito calificado en comparación con el 5-fluorouracilo. Sin embargo, su uso podría asociarse a una mayor incidencia de complicaciones.
