Abstract： The concept of treatment of central serous chorioretinopathy (CSC) has evolved dramatically with the understanding of its pathogenesis recently. Initial clinical studies found that CSC is a self-limiting disease, therefore advocated observation or conservative treatment was recommended. Further study by fundus fluorescein angiography indicated that CSC results from barrier dysfunction of retinal pigment epithelium (RPE), which leads to serous RPE and (or) neural retinal detachment; so laser photocoagulation to close RPE leakage points by its thermal effects became a strategy to treat CSC. Recent study by indocyanine green angiography revealed that increased choroidal vascular permeability can induce high hydrostatic pressure and focal RPE detachment, resulting in mechanical breakage of RPE barrier. This is likely the major pathological basis of CSC now. Photodynamic therapy (PDT) can embolize of choroidal capillary network, thereby preventing choroidal leakage caused by increased capillary permeability, and thus cure the CSC. However the search for the pathogenesis and better treatment of CSC is far from over.Further investigation about pathogenesis and improvement of diagnosis and treatment is an urgent need for clinic work, but also major issues challenging the wisdom of an ophthalmologist. We need to work together to promote more and better clinical and basic research of CSC.
