Abstract: This paper describes the development of a double TV camera system incorporated in a standard fundus camera for imaging the choroidal vascular network with very low intensity infrared light. The equipment was employed to perform indocyanine green (ICG) choroidal angiography in several chorioretinal pathologies with particular interest in age related macular degeneration (AMD). An evaluation and comparison of fluorescein and ICG angiograms is carried out for the diagnosis, localization, and laser treatment evaluation of choroidal neovascularizations (CNV).
