Indocyanine Green Angiography

Turk J Ophthalmol. 2024 Feb 22;54(1):38-45. doi: 10.4274/tjo.galenos.2023.89735.

Abstract

The choroid plays an important role in the pathophysiology of the eye. Multimodal imaging offers different techniques to examine the choroid. Fundus fluorescein angiography offers limited visualization of the deep layers of the fundus due to the barrier property of the retinal pigment epithelium. Therefore, indocyanine green angiography (ICGA) is widely used in the angiographic examination of the choroidal structure. 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.

Keywords: Indocyanine green; angiography; choroid; diagnosis; imaging; retina; treatment.
