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 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 ...

Indocyanine green fluorescence angiography of the choroid.

Indocyanine green fluorescence (ICG) angiography of the choroid gives better visualization of the choroidal vessels than does fluorescein angiography. We found that the detachment of the pigment epithelium seems bigger on ICG than on fluorescein angiograms, and pigmented lesions are more clearly delineated.
