    Abstract:
    PURPOSE: To evaluate the effect of half-dose verteporfin photodynamic therapy (PDT) on macular function in cases of central serous chorioretinopathy (CSC). DESIGN: Interventional case series. METHODS: A total of 24 eyes from 24 cases of CSC were included in this study. In each eye, at baseline and 1, 3, and 6 months after half-dose PDT, logMAR best-corrected visual acuity (BCVA); central 10-degree, 20-degree, and paracentral 10-degree to 20-degree retinal sensitivity; and also mean retinal sensitivity results for each case over the area that was treated with half-dose PDT (PDT spot area) by MP-1 microperimetry and optical coherence tomography (OCT) foveal morphologic changes were assessed. The MP-1 microperimetry sensitivity map was overlaid onto an indocyanine green angiography image recorded on a Heidelberg scanning laser ophthalmoscope using dedicated MP-1 software to evaluate the PDT laser spot area. RESULTS: After treatment, BCVA and central 10-degree, 20-degree, paracentral 10-degree to 20-degree, and PDT laser spot area retinal sensitivity were improved significantly. In OCT in 20 of 24 eyes (83%), subretinal fluid (SRF) was resolved 1 month after half-dose PDT. At 3 and 6 months after treatment, SRF was resolved at all eyes. None of the patients in this study developed any systemic or ocular adverse events associated with verteporfin treatment. CONCLUSION: Half-dose verteporfin PDT induced a significant increase in central 10-degree, 20-degree, paracentral 10-degree to 20-degree, and also PDT laser spot area retinal sensitivity over 6 months in cases of CSC.
