Abstract
Purpose: The aim of this study is to investigate the effect of half-fluence photodynamic therapy (PDT) in chronic central serous chorioretinopathy (CSC). Materials and Methods: Forty-two eyes of 34 patients with chronic CSC and symptoms for at least 6 months were retrospectively reviewed. All eyes were treated with indocyanine green (ICG)-guided half-fluence PDT. The primary outcome measure was the proportion of eyes with complete resolution of subretinal fluid (SRF) on spectral domain-optical coherence tomography (SD-OCT). The secondary outcome measure was change in best corrected visual acuity (BCVA). SPSS v. 16 software was used for statistical analysis. Results: The mean follow-up period was 12.5 ± 4.3 months. Twenty six (78.78%) eyes showed complete resolution of SRF (P Conclusion: Half-fluence PDT is an effective and safe method in the treatment of chronic CSC with stabilization or improvement of anatomical and functional outcomes.
