In order to examine the retina (the back of the eye) more closely, your ophthalmologist may use a diagnostic technique called Fluorescein Angiography.
A harmless (vegetable-based) fluorescent dye is injected into a vein in your arm, where it travels throughout the blood vessels in your body, illuminating them. As the dye passes through the blood vessels in the eye, a special camera takes photographs of the retina tracking the blood flow.
WHY IS FLUORESCEIN ANGIOGRAPHY PERFORMED?
Fluorescein angiography helps your ophthalmologist see what is happening in your retina, highlighting any abnormalities that may be present. The images from fluorescein angiography help your doctor decide on the best course of treatment for your condition. The procedure will also be performed to monitor progression of your condition and the effectiveness of treatment. It is used most often to monitor two conditions: Age–Related Macular Degeneration (AMD) and the effects of Diabetes on the eyes.
