Fluorescein Angiography (FA)
Fluorescein angiography, also called a fluorescein angiogram (fluorescein – the type of dye that is used; angiogram – a study of the blood vessels – in this case, on your retina) is a valuable test that provides information about the condition of the retina.
Fluorescein angiography is useful for evaluating many eye diseases that affect the retina in the back of the eye.The study is performed by injecting a sodium-based dye into an arm vein. The dye appears in the blood vessels on the retina in 10-15 seconds on average. As the dye travels through the retinal blood vessels, an ophthalmic photographer shoots pictures of the retina with a special retinal camera. If there are any abnormalities on the retina, the dye will usually reveal them by leaking, staining or by its inability to get through blocked blood vessels.
Although statistically very rare, adverse reactions to the intravenous dye have been reported. You should discuss the risks and benefits of this common study with your ophthalmologist.
At The Macula Center, these photos are taken with a digital camera system, allowing Dr. Deupree to interpret the results immediately.
