  • Fluorescein Angiography (FA) is a diagnostic procedure that uses a special camera to record the blood flow in the RETINA – the light sensitive tissue at the back of the eye.

The test does not involve any direct contact with the eyes. Your eyes will be dilated before the procedure.

Fluorescein dye is injected into a vein in the arm/hand. As dye passes through the blood vessels of your eye, photographs are taken to record the blood flow in your retina. The photographs can reveal abnormal blood vessels or damage to the lining underneath the retina.

The images will be captured in black and white. The dye will fluoresce in the blood vessels and be recorded as light grey or white in the image. Interpretation of the abnormal angiogram relies on the identification of areas that exhibit hypofluorescence (darkness) or hyperfluorescence (brightness).

Fluorescein angiograms are often recommended to follow the course of a disease and to monitor treatment results. It is particularly useful in the management of diabetic retinopathy and macular degeneration.
