    Abstract:
    PURPOSE: To compare the efficacy and safety of half-dose vs. half-fluence vs. standard photodynamic therapy (PDT) in patients with chronic central serous chorioretinopathy (cCSC). METHODS: This retrospective study included 64 eyes of 61 patients with cCSC who were treated with half-dose PDT (verteporfin 3 mg/m2 and light energy 50 J/cm2), half-fluence PDT (verteporfin 6 mg/m2 and light energy 25 J/cm2) or standard PDT (verteporfin 6 mg/m2 and light energy 50 J/cm2). The complete resorption of subretinal fluid (SRF) and changes of best corrected visual acuity (BCVA) and central retinal thickness (CRT) over the follow-up period were also assessed. RESULTS: Fifteen eyes (65.2 %) in the half-dose PDT group, 12 eyes (80 %) in the half-fluence PDT group, and 20 eyes (76.9 %) in the standard PDT group showed complete resolution of SRF. There were no statistically significant differences in the mean BCVA improvement, CRT and SRF height reduction, number of PDT sessions, complete success, and recurrence rates between groups (p > 0.05). None of the eyes with intact EZ showed failure. There were positive correlations between higher mean CRT values of the last visit, 1st, 3rd, 6th months and failure. None of the treated eyes (0%) developed any systemic or local adverse events. CONCLUSION: Half-dose, half-fluence or standard PDTs are all effective and safe treatment choices in cCSC with similar BCVA improvements and CRT reductions. The higher mean CRT values of the follow-up period were correlated with failure, and in eyes with intact EZ showed no failure.
