<unk>  <unk>  is a diagnostic procedure used to examine choroidal blood flow and associated pathology.<unk><unk>  <unk>  is a water soluble cyanine dye which shows fluorescence in near-infrared (790–805 nm) range, with peak spectral absorption of 800-810 nm in blood. The near infrared light used in<unk>  penetrates ocular pigments such as melanin and xanthophyll, as well as exudates and thin layers of sub-retinal vessels. Age-related macular degeneration is the third main cause of blindness worldwide, and it is the leading cause of blindness in industrialized countries.<unk>  is widely used to study choroidal neovascularization in patients with exudative age-related macular degeneration. In nonexudative AMD,<unk>  is used in classification of drusen and associated subretinal deposits.
