Fluorescein Angiography

It is an eye test in which a fluorescent dye and a special camera are used in order to take photos and look at blood flow in the retina and choroid.

How the test is performed:

Eye drops are given to make your pupil dilate. Patients are asked to place their chins on a chin rest and their foreheads against a support bar to keep their heads still during the test.

The health care provider will take pictures of the inside of the eye, and then a dye called fluorescein is injected into a vein. Most often it is injected at the inside of your elbow. A camera-like device takes pictures as the dye moves through the blood vessels in the back of your eye. (Pictures are taken up to 20 minutes after you have been given the injection.)

Before the test starts, a history of allergies is performed in case the patient is allergic to the fluorescein dye.
