. Indocyanine green angiography in central serouschorioretinopathy

摘要

The pathogenesis of central serous chorioretinopathy (CSC) is still under discussion. Using indocyanine green angiography ('ICG.-A), numerous authors have observed hyperfluorescent lesions related to choroidal hyperpermeabil-ity, thus giving new support to the hypothesis of a choroidal pathogenesis for CSC1"6. Delayed choroidal perfusion has also been observed1,6, leading to the hypothesis that capillary or venous congestion after ischemia in one or more choroidal lobules might be the cause of choroidal hyperpermeability.Here we report the findings obtained with ICG-A in a large group of patients, analysing above all the images which are seen in the late phases.
