WebThe retention of ICG in the fenestrated choroidal circulation, combined with its low permeability, makes ICG angiography ideal for viewing the choroidal blood vessels. Once injected, ICG binds to plasma proteins and quickly circulates to the choroid layer, delineating the choroidal veins within 15-20 secs. How safe is ICG? Indocyanine green angiography (ICGA) is a diagnostic procedure used to examine choroidal blood flow and associated pathology. Indocyanine green (ICG) 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 ICGA penetrates ocular pigments such as melanin and

ICG absorbs near infra-red, especially light with a wavelength of about 805 nanometers. A laser of that wavelength can penetrate tissue. That means, dying tissue with injected ICG allows an 800 nm to 810 nm laser to heat or overheat the dyed tissue without harming the surrounding tissue.
