Indocyanine green angiographic findings in central serous chorioretinopathy.
There has been great controversy about the pathogenesis of the focal changes in the retinal pigment epithelium (RPE) causing detachment of the neurosensory retina in central serous chorioretinopathy (CSC). This study was performed to evaluate changes in choroidal perfusion in 15 patients with CSC. Fluorescein and indocyanine green (ICG) angiography was performed in patients with acute or chronic recurrent CSC. In all patients delayed arterial filling followed by capillary and/or venous congestion, in some cases adjacent to ischemic areas, was found in the choroid. Leakage from the RPE in fluorescein angiography was only observed in those areas with choroidal capillary and/or venous congestion. The preliminary results suggest that venous congestion possibly in association with ischemia causes hyperpermeability of choroidal vessels already described in the literature.
