Fluorescein angiography is an eye test that uses a special dye and camera to look at blood flow in the retina and choroid.
A fluorescein angiogram looks at the blood vessels and the lining at the back of your eye (the retina). This test can pick up changes in the condition of your eyes. It can help the specialist make a diagnosis or tell them how well treatment is working.
Although commonly referred to as fluorescein, the dye used for fluorescein angiography is actually fluorescein sodium (C20 H10 Na2 O5). It is the water-soluble salt of fluorescein, also known as resorcinolphthalein sodium.
