Fluorescein Angiography
Fluorescein angiography (FA) is obtained by injecting a small amount of a non-iodine based dye into a vein in the arm.  As the dye travels through the retinal vessels, photographs are taken.  Areas where the dye is leaking becomes more visible than it should be. Sometimes the dye is less visible when blood vessels are blocked.  This information assists in diagnosis of various diseases and guides treatment options.  The fluorescein dye naturally leaves the body.  Occasionally, patients will notice a temporary color change in their urine and/or skin; however, this reverts back to normal within a day.
