We performed indocyanine green (ICG) angiography in 20 eyes of idiopathic choroidal neovascularization. The patients were aged between 29 and 49 years, average 40 years. Choroidal neovascularization (CNV), was detected in 17 eyes. All the 20 eyes showed a dark rim around the lesion. Out of 10 eyes with CNV larger than one half of disc area, ophthalmoscopy showed subretinal pigmented halo or plaque in 7 eyes and ICG angiography showed a dark halo or plaque within the area of CNV in all the eyes. Abnormalities of the choroid in areas other than the CNV were found in 11 eyes, 55%. These findings seemed to show that the CNV is located posterior to sensory retina and that the ICG findings can be useful in differentiating from age-related macular degeneration. There is a possibility that the ChorOidal abnormality is pathogenetically related TO CNV.
