Indocyanine Green: Observations

Indocyanine green 1 (ICG) is a tricarbocyanine dye (Figure 1) which has been used in the indicator dilution technique for measuring cardiac output (1, 2). Animal studies (3) and preliminary observations of human subjects (4, 5) have suggested that this dye may have characteristics that could make its uptake, storage, and excretion by the liver helpful indices of hepatic function. The present in...

Indocyanine Green angiography in Uveitis

Indocyanine green accused.

T he concept of retinal vital staining is not new. There has however been renewed interest in the subject since indocyanine green (ICG) was introduced as a vital stain to highlight the internal limiting membrane (ILM) during macular surgery. ICG’s well known role in cardiac and choroidal angiography exploits its properties as a fluorophore, but its role as a macular vital stain relies on its pr...

Indocyanine green angiography.

A brief survey of the recent ophthalmic literature underscores a resurgence of interest in indocyanine green angiography (ICGA). This imaging method may be particularly useful for the ophthalmologist, as it provides at least a theoretical advantage for improved imaging of the choroidal circulation when compared with fluorescein angiography. New temporal and spatial technological advances (that ...

Endotoxin-induced reduction in biliary indocyanine green excretion rate in a chronically catheterized rat model.

Using a nonstressed chronically catheterized rat model in which the common bile duct was cannulated, we studied endotoxin-induced alterations in hepatic function by measuring changes in the maximal steady-state biliary excretion rate of the anionic dye indocyanine green (ICG). Biliary excretion of ICG was calculated from direct measurements of biliary ICG concentrations and the bile flow rate d...
