RESUMENObjetivo: Determinar la eficacia y seguridad de la terapia fotodinámica en coriorretinopatía serosa central crónica (CSC) Métodos: Se incluyen pacientes con formas cróni-cas de CSC y signos de actividad de la enfermedad tratados con terapia fotodinámica. Se lleva a cabo una exploración oftamológica completa incluyendo la medida de mejor agudeza visual corregida (MAVC) en optotipo ETDRS, angiografía con fluoresceína (AFG) y verde de indocianina (AVI) y tomografía de coherencia óptica (OCT). El objetivo primario del estudio es determinar el cambio medio en agudeza visual. Resultados: Se han incluido 11 ojos de 11 pacientes. La MAVC media ha pasado de 20/76 a 20/64. El 35% de los ojos mejoraron su MAVC en dos o más líneas, en el 45% se mantuvo estable y el 18% perdieron dos o más líneas. En todos los casos se redujo la hiperpermeabilidad coroidea y en un 80% el desprendimiento de retina neurosensorial. Todos los pacientes recibieron un solo tratamiento salvo un caso que requirió dos por la aparición de una neovascularización coroidea (NVC). En otro caso ARTÍCULO ORIGINAL ABSTRACT Objective: To determine the efficacy of Photodynamic Therapy (PDT) in chronic Central Serous Chorioretinopathy (CSC). Methods: Patients diagnosed with chronic CSC, with clinical evidence of activity and treated with Photodynamic Therapy, are included in this report. All were assessed by a complete ophthalmological examination, including assessment of the best corrected visual acuity (BCVA) using an ETDRS chart, fluorescein and indocyanine angiography and optical coherence tomography (OCT). The main objective of the study was to determine the mean visual acuity change. Results: 11 eyes of 11 patients were included in the study, which had a mean follow-up period of 11 months. The mean BCVA increased from 20/76 to 20/64. 35% of eyes improved their BCVA by 2 lines or more, 45% remained stable and 18% lost 2 lines or more. Choroidal hyperpermeability was reduced in every case. Neurosensorial retinal detachment decreased in 80% of cases. Only one eye received a second PDT treatment due to choroidal neovascularization. An increase of atrophy over the Retinal
