Patients and methods: The medical records of 64 eyes from 60 patients with chronic CSC were retrospectively reviewed; 36 eyes received low-fluence PDT (25 J/cm2) and 28 eyes received half-dose verteporfin PDT (3 mg/m2). The primary outcome measure was the proportion of eyes with complete resolution of subretinal fluid. Secondary outcome measures were the changes in best corrected visual acuity (BCVA) and central foveal thickness, and the proportion of eyes that showed an increase of ≥5 letters in BCVA at the last visit. Results: The mean follow-up period was12.5±4.3 months and 13.1±4 months in the low-fluence group and half-dose group, respectively (P=0.568). Thirty-three eyes (91.6%) in the low-fluence group and 26 eyes (92.8%) in the half-dose verteporfin group showed complete resolution of subretinal fluid (P=0.703). BCVA increased by a mean of 7.4 letters and 4.8 letters in the low-fluence group and half-dose group, respectively (P=0.336). Seventeen eyes (52.8%) in the low-fluence group and 14 eyes (50%) in the half-dose group experienced a gain of ≥5 letters in BCVA (P=0.825). In the low-fluence and half-dose verteporfin group, the mean baseline central foveal thickness was 351±90 µm and 341±96 µm, and significantly decreased to 188±61 µm and 181±47 µm, respectively (P<0.01). Conclusion: Both treatments resulted in complete subretinal fluid resolution in most of the eyes, with significantly better visual acuity outcomes compared to baseline at the last visit.
