Indocyanine green angiograms of central serous chorioretinopathy in 30 eyes were evaluated in order to demonstrate the pathologic features of the retinal pigment epithelium. In 5 of the cases, the dye leakage or the pigment epithelial degeneration was seen to be associated with areas of choroidal circulatory insufficiency. This implies that local choroidal ischemia is one of the causes of the pigment epithelial disturbance.
