[Indocyanine green angiography in central serous chorioretinopathy]
1Department of Ophthalmology, Peking Union Medical College Hospital, Beijing.
Objectives:
To know the results of indocyanine green angiography (ICGA) in central serous chorioretinopathy (CSC) and approach its pathogenetic mechanisms.
Methods:
20 cases of CSC were examined by scanning laser ophthalmoscope to perform blue laser beam examination, fundus fluorescein angiography (FFA) and indocyanine green angiography.
Results:
(1) The blue laser beam: The elevation lesions of the sensory retinal and retinal pigment epithelial detachment were clearly found. (2) ICGA: In the early phase, choroidal delayed filling (95.0%), choroidal hyper-perfusion (80.0%), choriocapillary dilatation, and in the late phase, hyperfluorescent spots (95.0%), diffuse choroidal hyperfluorescence (77.5%), abnormal fluorescence over vortex vein were found. (3) FFA demonstrated the hyperfluorescence of the choroidal background and the optic disc.
Conclusions:
CSC patients have obvious choroidal circulatory disorder and the ICGA is a good method for the study of the pathogenetic mechanisms of the CSC and its therapeutic evaluation.
