RecruitingDrug trialChoroidal Blood Flow in Acute and Chronic Central Serous ChorioretinopathyPatients with central serous chorioretinopathy (CSC) will be monitored with laser speckle flow graphy (LSFG), swept source optical coherence tomography (SS-OCT) and SS-OCT angiography (SS-OCTA). The aim is to unveil the flow and pulse wave characteristics of the choroidal circulation in acute CSC and chronic CSC.
