Indocyanine green angiography in classic choroidal neovascularization

The indocyanine green (ICG) angiographic features of classic choroidal neovascularization (CNV) were evaluated in the 66 consecutive patients (70 eyes) by ICG angiography using the scanning laser ophthalmoscope. All patients had classic CNV documented by fluorescein angiography. Indocyanine green angiographic findings of classic CNV were as follows: Vessel architecture in 66% (46 of 70) of eyes, feeding vessels in 29% (20 of 70), and late hyperfluorescence in 93% (65 of 70) of eyes. Borders of classic CNV were found well-defined in 47% (33 of 70), and ill-defined in 49% (34 of 70) of eyes. In the remaining 4% (3 of 70) of eyes ICG angiography did not detect CNV. Our study indicates that fluorescein angiography remains the method of choice in the diagnosis of classic CNV. Indocyanine green angiography provides more information in the detection of feeding vessels of classic CNV.
