Fluorescein angiography (an eyecare service of our Fort Lauderdale office) is a diagnostic procedure which uses a special camera to take a series of photographs of the retina. A special water-soluble fluorescein dye is injected into a vein in the arm. The dye travels through the veins and into the arteries as it circulates throughout the body. As the dye passes through the blood vessels of the retina, a special camera flashes a blue light into the eye and takes multiple photographs of the retina. If the blood vessels are abnormal, the dye may leak into the retina or stain the blood vessels. If there is damage or leakage the precise location will be revealed.
