2023年8月25日 · Indocyanine green angiography is an important invasive imaging modality among many diagnostic imaging modalities used in retinochoroidal diseases. It helps to study the anatomy, physiology, and pathology of choroidal and retinal circulation. It has an important role in the diagnosis of various ocular pathologies.

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.

Indocyanine green angiography (ICGA) provides improved imaging of choroidal vasculature compared to fluorescein angiography. Because of the excitation and emission properties of indocyanine green (excitation at 790 nm and emission at 835 nm), pathologies involving retinal and choroidal vascular systems can be imaged even in the presence of ...

Indocyanine Green Chorioangiography (ICG) is a procedure which images a layer of the posterior part of the eye. This layer, the choroid, is deeper than the retina and normally obscured by pigmentation. The choroid contains a unique network of blood vessels.

ICGA is an important component of multimodal imaging in the diagnosis and treatment of many degenerative, tumoral, and inflammatory diseases of the choroid and retina. This review presents the general characteristics of ICGA and a practical approach to its clinical use.

Indocyanine green angiography, or ICG angiography for short, is used primarily in vascular neurosurgery. This simple and harmless procedure can be used to visualize the blood flow through the cerebral vessels in real time during surgery.

Indocyanine green (ICG) angiography offers the theoretical advantage of detecting abnormalities such as choroidal neovascularization (CNV) in areas that may be blocked by hemorrhage. However, ICG angiography of such eyes has not consistently produced the same images of CNV as seen by fluorescein angiography and is therefore not routinely used.

ICG angiography provides good video angiograms of the choroid, demonstrating choroidal vascular closure in eyes with macular involvement and hypofluorescence corre-

2023年8月25日 · Indocyanine green angiography (ICGA) is used to image the choroidal circulation and its abnormalities. Even though fundus fluorescein angiography (FFA) is a good tool for imaging retinal circulation in great detail, its ability to image the choroidal circulation is limited by the poor transmission o …

Indocyanine Green (ICG) Angiography, often used to complement Fundus Fluorescein Angiography (FFA), is a procedure used to acquire images of the choroidal vasculature. Indocyanine Green is a water-soluble dye which is almost entirely protein-bound (98%) which limits its diffusion out of the choroidal vasculature.
