Angiography

Angiography is a test that allows detailed views of retinal blood vessels and the choroid, and to map the back of the eye.

This diagnostic test produces imaging of the back of the eye with a device called angiographer, after injecting contrast media such as fluorescein or indocyanine in the eye. Such imaging may reveal vascularization disorders which are more difficult to appreciate in a retinography, they are used to map the retinal vascular tree.
