Eye Angiogram

Angiography, Fluorescein, Fluorescein Angiography, Fluorescein Dye Test, Indocyanine Green Test

Test Overview

An eye angiogram uses a yellow dye (fluorescein) and a camera to take pictures and evaluate the blood flow through the vessels in the back of the eye (retina).

During an eye angiogram, the dye is injected into a vein in your arm. Once injected, it takes about 10 to 15 seconds to circulate through your body. As the dye enters the blood vessels in your eyes, a series of photos are taken to chart the dye's progress. More pictures are taken after most of the dye has passed through your eyes to see whether any of it has leaked out of the blood vessels. Any dye that leaks out of the blood vessels will colour the tissues and fluid in the eye. Filters in the camera allow the areas coloured by the dye to show up in the photos.

A dye called indocyanine green may be substituted for fluorescein. It allows the health professional to see whether the blood vessels underneath the retina are leaking.

Unlike other angiogram procedures, an eye angiogram is not an X-ray procedure, so you are not exposed to any radiation.
