Abstract: Central serous chorioretinopathy (CSC) is a common eye disease. It may be a thick choroidal spectrum disease associated with polypoid choroidal vasculopathy (PCV). Fluorescein angiography and indocyanine green angiography (ICGA) are still classic diagnostic methods. ICGA can reveal abnormalities in the choroidal vascular system of the disease. Optic coherence tomography angiography (OCTA) can detect retinal and choroidal vascular abnormalities in different layers. Retinal photocoagulation and photodynamic therapy are still the main treatments for CSC. For lesions in the near macular area, 577 nm subthreshold micropulse laser photocoagulation can be used, which is safer. (Int Rev Ophthalmol, 2019, 43: 166-169)
