Pachychoroidopathy is a type of retinal choroidal disease with similar clinical features, which is characterized by attenuation of the choriocapillaris overlying dilated choroidal veins, and associated with progressive retinal pigment epithelium dysfunction and neovascularization. At present, pachychoroidopathy includes pachychoroid pigment epitheliopathy, central serous chorioretinopathy pachychoroid neovasculopathy, polypoidal choroidal vasculopathy, focal choroidal excavationm, and peripapillary pachychoroid syndrom. These diseases not only have common imaging features, but also individual imaging features. This not only provides us with important clues about the pathogenesis of pachychoroidopathy, but also provides guidance for their treatment decisions. Although the exact pathogenesis of pachychoroidopathy is still unclear, and the treatment method is still controversial; but it is believed that with the development of imaging technology and the development of high-quality clinical and basic research, patients with pachychoroidopathy can be provided with more reasonable treatment in the future.
