Digital Fundus Fluorescein Angiography (FFA) is a diagnostic procedure that uses a fluorescent dye injected into the bloodstream to highlight the blood vessels in the retina. As the dye circulates through the eye, a specialized camera captures rapid sequential photographs, revealing vascular abnormalities, leakage patterns, and areas of poor blood flow.
A fluorescent dye (fluorescein sodium) is injected into a vein in the arm. As the dye travels through retinal blood vessels, a specialized camera with filters captures detailed images over several minutes. The entire procedure takes about 10–15 minutes in the clinic.
FFA is invaluable for diagnosing diabetic retinopathy, macular degeneration, retinal vein occlusion, and inflammatory eye conditions. It reveals areas of poor blood flow, abnormal new vessel growth (neovascularization), and fluid leakage from damaged vessels.
After dye injection, you may notice temporary yellowing of the skin and urine for 24–48 hours. Pupils will be dilated for the test, so arrange for someone to drive you home. Mild nausea occurs rarely. Serious allergic reactions are extremely uncommon.
