Fundus Fluorescein Angiography (FFA) is an essential test utilized by our skilled retina specialists to diagnose and monitor various retinal conditions. Whether you're facing issues like diabetic retinopathy or macular degeneration, we ensure a smooth and comfortable experience through this advanced imaging technique.
Fundus Fluorescein Angiography (FFA) is a specialized imaging test used to view blood flow in the retina and choroid. This quick and effective procedure is key in diagnosing various retinal conditions, and our retina specialists' rely on FFA to ensure you receive the best care possible.
Fundus Fluorescein Angiography (FFA) is an imaging method designed to capture detailed pictures of the blood vessels at the back of your eye. By injecting a fluorescent dye called sodium fluorescein into a vein, usually in the arm, the test highlights blood circulation in the retina and the choroid, which are crucial for clear vision. The images produced help our Retina Specialists' identify issues such as leaky, blocked, or abnormal blood vessels.
Our retina specialists' may suggest FFA when there is a need to investigate abnormalities that could be affecting your vision. This imaging test is especially helpful in diagnosing conditions related to retinal blood vessels. Here are the most common reasons for recommending FFA:
To detect signs of leaking blood vessels or areas with impaired circulation, which can lead to vision problems if untreated.
To examine abnormal blood vessel growth beneath the retina that adversely affects central vision.
To assess the blood flow and pinpoint regions where blockages may be causing issues.
To uncover any hidden regions of retinal damage or leakage that might not be apparent during a regular eye exam.
To locate specific areas where fluid accumulation is impacting visual clarity.
Understanding what happens during the FFA test can help you feel more at ease about the process. This test is typically conducted on an outpatient basis, meaning you can return home after the procedure. Here’s a step-by-step look at what you can anticipate during your appointment:
Before beginning the actual procedure, a few preliminary steps are taken to ensure high-quality imaging and patient comfort. Your eyes will be prepared with special dilating drops that widen your pupils, allowing for a clear view of the retina. You may also be asked to avoid eating for a couple of hours prior to the test to reduce any risk of nausea. It is important to inform our Retina Specialists' of any allergies, especially to medications or contrast dyes, so that we can take all necessary precautions.
The FFA procedure is both quick and painless. Here’s what happens during the procedure:
Staying relaxed and following the instructions of our Retina Specialists' during the test will help produce images that truly capture the health of your retinal circulation.
While Fundus Fluorescein Angiography (FFA) is generally safe, knowing a few potential side effects can help set your mind at ease. Most patients experience minimal discomfort and very few complications.
Some individuals notice a brief feeling of nausea shortly after the dye is injected. This sensation usually lasts just a few seconds.
It is common for the dye to give your skin a slight yellow tint and turn your urine bright yellow or orange for up to several hours as it is cleared from your body.
A small number of patients may experience itching or a mild rash. These reactions are easily managed with antihistamines if necessary.
Severe allergic responses, such as difficulty breathing or anaphylaxis, are extremely rare. However, if you have a history of severe dye allergies or other serious allergic reactions, it is important to inform our Retina Specialists' before the test.
FFA is safe for most people, but there are specific groups for whom the test might be contraindicated or approached with caution:
FFA is usually avoided during pregnancy unless it's really necessary. There aren't any known risks to the baby, but doctors prefer to be cautious.
If you've had bad reactions to dyes like fluorescein, you need to be careful. If you still need FFA, your doctor might want to consult with other specialists, do it in a hospital, and give you medicine to prevent a reaction.
If you've had a severe allergic reaction before, your doctor will want to assess you carefully before doing FFA.
If you have serious diseases like heart attacks, cancer, or severe kidney or liver problems, your doctor will need to evaluate you carefully before FFA. However, if you have mild kidney problems or are on dialysis, FFA is generally safe.

Think of FFA as a highly detailed map that pinpoints where improvements are needed. This information is central to managing your eye health proactively and preventing further vision loss.
No, FFA is not a painful procedure. The injection of the fluorescent dye might cause a brief sensation, but the process itself is largely painless. Any discomfort is typically mild and temporary.
The eye drops used to dilate your pupils can leave your vision blurry for a few hours after the test. This temporary side effect is normal, and it is why we advise against driving until your vision has returned to normal.
Minor side effects, such as slight nausea or temporary skin discoloration, are common and usually resolve on their own. However, if you experience any serious symptoms like breathing difficulties, severe itching, or swelling, please contact our office immediately or seek emergency care.
Yes, FFA can be repeated if necessary. For patients managing chronic eye conditions like diabetic retinopathy or macular degeneration, periodic FFA tests may be recommended to monitor disease progression and the effectiveness of treatments.
