This study is performed to evaluate the fluorescein and indocyanine green (ICG) characteristics of choroidal neovascularization (CNV) in age-related macular degeneration (ARMD). 200 eyes of 101 patients were examined with digital ICG videoangiography (ICGV). 190 of the 200 eyes had macular lesions of ARMD, and CNVs were detected in 84 (44.2%) of them. Angiographies confirmed the presence of well-defined CNV in 40 (47.6%) eyes and occult CNV in 44 (52.4%) eyes. On ICG-videoangiographic examination, 6 (13.6%) of the 44 eyes with occult CNV had vascularized pigment epithelial detachment, 27 (61.4%) had a vascularized retinal pigment epithelium. Laser photocoagulation had been performed on the remaining 11 (25%) eyes. The results of this study suggest that ICGV is a valuable technique in the diagnosis and evaluation of occult CNVs and may be suggested as an additional diagnostic tool in cases with choroidal neovascular membranes.
