PURPOSE: The purpose of this study was to evaluate the results of fluorescein angiography-guided photodynamic therapy with half-dose verteporfin in the treatment of chronic central serous chorioretinopathy with focal leakage areas.
METHODS: Eight cases with a history of central serous chorioretinopathy of ≥6 months were included. All eyes had one or more focal areas of active retinal pigment epithelial leak. Photodynamic therapy was applied with half-dose verteporfin (3 mg/m²), and the spot size was set limited to the area of active leakage shown on fluorescein angiography.
RESULTS: The mean duration of the last central serous chorioretinopathy episode was 12.50 months. The mean best-corrected visual acuity improved from 20/122 to 20/60 the first month (P = 0.017) and to 20/55 the first year after treatment (P = 0.018). Seven eyes (87.5%) had improved vision 1 year after treatment, and 1 eye (12.5%) had stable vision with a mean number of 3.61 gained lines. The mean central macular thickness was reduced from 366 ± 95 μm to 217 ± 32 μm the first month (P = 0.006).
CONCLUSION: Fluorescein angiography-guided photodynamic therapy with half-dose verteporfin seems to be a rational and effective alternative to other methods in the treatment of chronic central serous chorioretinopathy with focal leakage on fluorescein angiography.
