Abstract

Fluorescein angiography(FAG)has been used to identify retinal circulation, but it has limitations to detect any other ocular circulations. Recently new technology developed indocyanine green angiography(ICGA), which allows better enhanced imaging of the ocular structures, such as choroid and other subretinal structure as compared with FAG. The authors investigated the characteristic findings of ICGA in central serous chorioretinopathy, comparing with those of FAG finding. After performing ICGA and FAG in 74 patients(74 eyes)with acute forms of central serous chorioretinopathy, as follows, arterial filling, leaking pattern. ICGA study showed presumed choroidal hyperpermeability in the 42 eyes(56.7%), which are no leak on the FAG. ICGA study showed focal hyperfluorescence detected by FAG, corresponding to presumed choroidal hyperpermeability in 65 eyes(87.8%). Delayed choroidal filling areas were showed in ICGA(49 eyes, 66.2%). ICGA study showed presumed choroidal hyperpermeability in the 32 eyes(43.2%)corresponding leak noted on the FAG. Numbers of hyperfluorescent lesion was two in 40 eyes(54.1%)on the ICGA. Most of focal leaking areas were located in superonasal area. In central serous chorioretinopathy the authors suggest that choroid is the primary pathologic focus, the choroidal circulatory dysfunction and vascular hyperpermeability can be assumed to be a causative role in structural abnormality of the retinal pigment epithelium. In conclusion we think that the ICGA is effective method for diagnosis and treatment of the central serous chorioretinopathy.
