Fluorescein Angiography (IVFA)
Fluorescein angiography is a special diagnostic test used to enable your doctor to better visualize the blood vessels at the back of your eye, as well as assess certain conditions which effect the retina (the part of your eye that acts as the film in a camera does). Your eyes will be dilated before the test. We suggest that you eat something light before coming for your appointment. We ask that you arrive at our office 15 minutes before your appointment time so your eyes can be dilated.
Purpose of the Test
There are many reasons your doctor may request this test. Some of the more common conditions that require angiography are Diabetes Mellitus, macular degeneration, and swelling of the retina. Once the test is completed, it takes approximately 48 hours to develop the photographs, at which time your doctor will personally call you with the results.
The Procedure
The procedure is carried out as follows: a small amount of a special dye (not iodine) is injected into a vein in your arm, and a series of rapid photographs are taken of the back of the eye. The initial part of the procedure takes about one minute, and then five to fifteen minutes later, additional photographs are taken to complete the angiogram.
For your comfort and safety, please wear short of loose-fitting sleeves, and bring a driver.
Potential Side Effects
As with any procedure, there are a number of potential side effects from the injection of fluorescein dye.Occasionally, patients experience a little bit of nausea, but rarely experience vomiting. In addition, allergic reactions may develop to the dye and can produce hives, as well as asthmatic symptoms. Although extremely rare, fainting and a severe allergic reaction to the dye may occur. A physician will always be present in the office when this test is taken in case any medical problems develop.
If you have any further questions or concerns, please feel free to ask your doctor.
