Angiography
Fluorescein angiography is a common diagnostic test for the retina,
performed in the office to measure and photograph blood circulation
in the retina. It is useful in several retinal conditions and is
commonly performed for patients with diabetic retinopathy and
macular degeneration.
Patients are seated at the camera after the eyes have been dilated
with drops. Several photographs will be taken of each eye in
preparation for the angiogram. A small injection of dye
(fluorescein sodium) will then be given in a vein in the arm or the
back of the hand. There is a sharp pinch as when bleed tests are
taken, and then some warmth in the arm as the dye is injected.
Multiple photographs are then taken over the next few
minutes.
Shortly after the injection, some patients can experience mild
nausea for two to three minutes before it subsides. Rarely, there
may be a rash or itching after the test. Serious allergic reactions
are very rare, but please let us know if you are uncomfortable, or
have any concerns.
The dye utilized in this test is not the same intravenous contrast
dye you may be familiar with from CT scans or IVP (kidney) tests.
And fluorescein angiography uses visible light to image the retina;
no X-rays are involved.
Vision will be blurred and discolored after this test, and patients
may want to stay in the office for 15 or 20 minutes before leaving.
Driving is not advised after fluorescein angiography, and
sunglasees will make you more comfortable outside while your pupils
are dilated.
