Angiography is a diagnostic test that your ophthalmologist at Connecticut Retina Consultants uses for several purposes, including:
Your ophthalmologist might recommend you undergo fluorescein angiography to find out whether there’s sufficient blood flow to the blood vessels in the back of your eye.
Angiography is also a valuable tool for enabling your ophthalmologist to follow the course of your condition.
Fluorescein angiograms are the form of angiography used by the team at Connecticut Retina Consultants. The procedure involves injecting a fluorescein dye into a vein in your arm, much like having blood taken.
The fluorescein dye travels around your bloodstream and into your retinal circulation. Specialized cameras track the course of the dye through arteries, veins, and capillaries.
There’s no radiation like there would be if you had an X-ray. The fluorescein dye is vegetable-based and your kidneys filter it out of your blood. The dye does make your urine an orange color for up to 24 hours.
One in 20 patients experiences nausea, but this usually only lasts a few minutes. Other side effects are uncommon. Occasionally patients experience an allergic reaction that causes a mild skin rash or itching. Anaphylaxis, which is a severe allergic reaction, rarely happens, affecting around 1 in 150,000 patients.
A fluorescein angiogram typically takes 10-15 minutes. If you wear contact lenses, you should remove them before your test.
Your ophthalmologist begins the procedure by applying eye drops to dilate your pupils. This makes it easier to see the back of your eye clearly. You rest your head in the chin and forehead supports on the front of the angiography machine. These supports help keep your head perfectly still during the test.
Your ophthalmologist takes multiple pictures of the inside of your eye, then you receive the injection of fluorescein dye. Another series of photos follows the progression of the dye as it travels into the blood vessels at the back of your eye.
You can carry on with your day after the angiography procedure, but you need to avoid driving because of the eye-dilating drops. Your eyes can also be more sensitive to light for up to 12 hours after your fluorescein angiogram.
