Follow-up evaluation of indocyanine green angiographic findings in central serous chorioretinopathy

Abstract

Observations with indocyanine green (ICG) angiography by our group and other authors suggest a primary involvement of the choroid in central serous chorioretinopathy (CSC)^1–3. The main result of our studies was the constant observation of areas of dye diffusion in the choroid in correspondence with the pigment epithelial alterations that characterize CSC³. We proposed zonal hyperpermeability of the choriocapillaris as the primary lesion in CSC, leading to degenerative alterations of the retinal pigment epithelium and passage of fluid in the subretinal space³.
