Abstract:
We performed indocyanine green angiography(ICGA) in 21 eyes of 21 patients with acute central serous chorioretinopathy(CSC) to investigate choroidal cirulatory changes in this disease. Heidelberg retina angiograph (HRA) that using confocal scanning laser ophthalmoscope was used for ICGA. In the very early phase of HRA, 19 eyes(90%) demonstrated focal areas of delayed filling usually followed by distinctively fluorescent, dilated choroidal vessels running through or around these areas. After mid-phase, diffuse intrachoroidal hyperfluorescence surrounding these dilated vessels and suggesting increased leakage from them was seen in 19 eyes(90%). The focal delays of choroidal filling seemed to reveal choroidal ischemia involved in this disease process rather than physiological delays as they were topographically associated with choroidal hyperfluorescence in the later phase of HRA and leaking points on fluoresecein angiogram. Based on these findings, we suggest the choroid as the primary pathologic focus of acute CSC. Also we propose a scenario of pathogenesis, beginning with choroidal ischemia that leads to increased leakage from choroidal vessels, secondary changes of retinal pigment epithelium and passage of fluid in the subretinal space.
