[Central serous chorioretinopathy. Studies of the site of the lesion with indocyanine green].
Indocyanine green angiographies of 33 patients with central serous chorioretinopathy (CSC) were examined in order to find out whether the location of ICG exudation was correlated with other findings. Areas of delayed choroidal filling at the site of the hot spot were found in 27 patients (82%). The hot spot was usually located at the margin of such areas. Furthermore, it seemed correlated to a larger ciliary artery in 19 patients (60.6%). A detachment of the pigment epithelium was detected in 18% and showed a characteristic early hypo- and late hyperfluorescence. There is evidence that the exudation of indocyanine green indicates a primary choroidal disorder as the cause of CSC. Many clinical features, for example pigment epithelial detachments, are easier to explain with this hypothesis. A correlation of the hot spot with variation of choroidal filling has to be interpreted with caution. Yet, it seems feasible that the border between areas of different speed of filling is especially vulnerable and might therefore decompensate in the case of diseased regulation of the choroidal vessels, as has been postulated for CSC.
