Fundus fluorescein angiography is a procedure used to examine the tiny blood vessels in the eye. It is carried out by a specialist nurse and ophthalmic (eye) photographer. The procedure is used to help diagnose certain eye conditions. A dye called fluorescein (see below) is injected into a vein in your arm or hand.

What Is a Fluorescein Angiography?

A fluorescein angiography is a medical procedure in which a fluorescent dye is injected into the bloodstream. The dye highlights the blood vessels in the back of the eye so they can be photographed.

This test is often used to manage eye disorders. Your doctor may order it to confirm a diagnosis, determine an appropriate treatment, or monitor the condition of the vessels in the back of your eye.
