Objetivo: Describir los resultados obtenidos con la utilización de inyecciones intravítreas de bevacizumab para patologías vitreorretinales.
Materiales y métodos: Estudio retrospectivo unicéntrico donde se examinó la evolución de pacientes que recibieron al menos una inyección intravítrea de bevacizumab entre febrero de 2021 y marzo de 2024. Se recopiló información sobre edad, sexo, diagnóstico, agudeza visual mejor corregida inicial y final, cambio en al menos 1 décima, cumplimiento del esquema de tratamiento, motivo de suspensión del tratamiento, espesor macular inicial y final, y eventos adversos serios.
Resultados: El estudio incluyó 84 ojos de 77 pacientes con edad media de 56,3 años (rango: 23-89). Se administraron 218 inyecciones con un promedio de 2,56 inyecciones por ojo y 2,8 por paciente. Las principales patologías tratadas fueron edema macular diabético (34,52%) y edema macular secundario a oclusiones vasculares (33,3%). El esquema primario de 3 dosis se cumplió en el 72,62% de los casos. Se observó una mejora en la agudeza visual en el 72,1% de los pacientes con una reducción del espesor macular promedio de 110,74 µm. Los efectos adversos serios fueron poco frecuentes, con un caso de hipertensión arterial (0,4%) y un caso de desprendimiento de retina regmatógeno (0,4%).
Conclusión: El tratamiento con inyecciones intravítreas de bevacizumab resultó seguro y efectivo para mejorar la agudeza visual en patologías vitreorretinales y constituyó además una estrategia beneficiosa en cuanto a su costo en el contexto de la salud pública.
