Fluorescein Angiography

What is Fluorescein Angiography?

Fluorescein angiography is a test which allows the blood vessels in the back of the eye to be photographed as a fluorescent dye is injected into the bloodstream via your hand or arm. It is particularly useful in the management of diabetic retinopathy and macular degeneration. The test is done to help the doctor confirm a diagnosis, to provide guidelines for treatment, and to keep a permanent record of the vessels at the back of the eye. Fluorescein sodium is a highly fluorescent chemical compound that absorbs blue light with fluorescence. Although commonly referred to as fluorescein, the dye used in angiography is fluorescein sodium, the sodium salt of fluorescein. A common misconception is that it is a 'vegetable dye' rather than a synthetic.

How Is The Procedure Done?

The pupils will be dilated with eye drops and the yellow dye is injected into a vein in your arm. During the injection, there can be a warm feeling or a hot flush can be experienced. This only lasts seconds and then disappears. Following the injection, photos are taken quickly over a period of about 60 seconds as the dye enters the vessels at the back of your eye. The lights flashed at you may appear bright but will NOT damage your eyes. It is common for the skin to be pale yellow and the urine colored fluorescent yellow after the procedure and these may take two days to wear off.
