Procedures & Services > Diagnostic Testing > Fluorescein Angiography

Fluorescein Angiography is a diagnostic test that uses a special camera to take photographs of the retina. A special dye is injected into a vein of either the arm or the hand. The camera takes pictures of this dye as it travels through the blood vessels in the retina. It is not the same dye used in an x-ray angiogram.

The photographs taken of the retina during this test help determine if the vessels are abnormal. Abnormal blood vessels may leak the dye into the retina or the dye may stain the blood vessels. The dye test may reveal damage to the lining underneath the retina or the growth of new abnormal blood vessels. Dr. Radtke uses fluorescein angiography to help determine the cause and severity of retinal disorders, as well as the options for treatment.
