Fundus fluorescein angiography (FFA),also known as eye angiography, is a technique used to examine the blood vessels of the retina (the eye’s nerve tissue) and the choroid (the vascular layer that nourishes it) at the back of the eye.
For the procedure, the pupil is dilated with eye drops. Fluorescein dye is injected into a vein in the patient’s arm or hand. Once the dye reaches the eye’s blood vessels, it makes them visible. A special camera captures multiple images, which are then evaluated to determine whether there are any vascular problems.
Applications of Fundus Angiography:
The skin and mouth may appear yellow-orange, which resolves within about 6 hours. The urine may also turn orange but usually returns to normal within 24 hours.
