| Summary: | Central serous chorioretinopathy (CSC) is a chorioretinal disease that causes idiopathic serous retinal detachment (SRD), which is associated with one or more areas of pigment epithelial detachment (PED) or defect in the retinal pigment epithelium, also with characteristic ocular structural changes. CSC was classified as pachychoroid spectrum diseases (PSD); recent studies have found it mainly in Haller layer. Recent studies focused on the thick sclera in CSC patients, illustrated the close relation between which and choroidal circulation and put forward the probable pathogenesis similar to uveal effusion syndrome (UES). In addition, short axial length, hyperopia and shallow anterior chamber are also the characteristics in CSC patients, indicating that CSC is the disease not limiting to posterior oculus, but involving the whole oculus. This review summarizes the latest research advances on optical characteristics in CSC, providing the new ideas for further research on pathogenesis of CSC.
