Fluorescein Angiography

Fluorescein Angiography

Fluorescein Angiography is an imaging technique that allows for a view of the circulation of the retina and the layers beneath the retina highlighting any abnormalities. The test consists of injecting a small amount of a vegetable-based dye (sodium fluorescein) intravenously using a small needle in the arm. Blue colored flash photographs are then taken of the back of the eyes over the next ten minutes on film. These photographs highlight the circulation through the eye. Examination of these photographs can then give further information about one's eye condition. Note that this test is virtually painless and side effects are uncommon; occasionally, though, persons will get nauseous or get hives. Rarely a more severe reaction may occur.

The information derived from this study is very helpful in determining the cause of many retinal diseases and most commonly in evaluating Diabetic Retinopathy and Age-related Macular Degeneration.
