Early choriocapillaris changes after half-fluence photodynamic therapy in chronic central serous chorioretinopathy evaluated by optical coherence tomography angiography: Preliminary results

OCTA is a noninvasive imaging tool for detecting choroidal vascular changes after PDT in CSC. In this preliminary study of a limited number of CSC patients, choroiocapillaris perfusion seemed to decreased in very early period following half-fluence PDT and then returned to normal until 30 days of therapy.
