Advanced Technology and Diagnostic Precision
At Retina Consultants, PA, we use state-of-the-art digital imaging equipment that provides the clearest, most detailed pictures possible. This advanced technology allows us to capture high-resolution images instantly and review them with you during your visit.
Our modern digital systems capture high-contrast, rapid sequences for precise timing and secure storage. Immediate image review supports same-day discussion of preliminary findings, while secure digital records enable objective monitoring of disease response over time and easy future comparison using confocal scanning laser systems or high-sensitivity fundus cameras.
We often combine your fluorescein angiography results with other tests like optical coherence tomography (OCT) and fundus photography to get a complete picture of your retinal health. While OCT shows retinal microstructure in cross-section, fluorescein angiography uniquely visualizes leakage, pooling, staining, and perfusion defects that directly influence treatment choices. OCTA maps flow without dye but cannot show leakage or late staining, and indocyanine green angiography better visualizes the choroid and polypoidal lesions; visual field testing is added selectively when functional mapping will influence management.
Ultra-widefield FA often alters staging and treatment by revealing peripheral non-perfusion not seen on standard views. By identifying peripheral ischemia, it can change grading and prompt targeted or panretinal photocoagulation in appropriate cases for diseases like diabetic retinopathy and retinal vein occlusion.
Fluorescein dye does not expose you to ionizing radiation and is generally very safe. However, it is a synthetic, pharmaceutical dye, not plant-based. Allergic reactions are uncommon but possible, and our team is fully trained to monitor for and manage them promptly with appropriate staff training, equipment, and medications on hand.
Preparing for Your Fluorescein Angiography
Proper preparation helps ensure your test goes smoothly and safely. Our staff will provide you with specific instructions based on your individual health needs and medical history.
Please tell our retina specialists about any allergies you have, especially to medications or dyes. Fluorescein does not contain iodine; shellfish or ‘iodine’ allergy is not a contraindication to FA. Let us know if you have kidney problems, heart disease, or if you might be pregnant. If you take blood thinners or have diabetes, bring a complete list of all medications and supplements you are currently taking so we can plan safely.
Most patients should not drive for several hours after the test because we need to dilate your pupils with eye drops. The dilation causes blurred vision and makes your eyes very sensitive to light. Please arrange for someone to drive you home, or plan to use public transportation or a ride-sharing service.
Bring your insurance cards, a photo ID, and any previous eye records or test results from other doctors. Sunglasses are very helpful for comfort after the procedure since your eyes will be sensitive to light. Consider bringing a book or tablet to help pass time during the waiting periods.
You may eat normally before the test unless our staff gives you different instructions. However, some patients feel slightly nauseous from the dye, so you might want to avoid a large meal right before your appointment. Staying well-hydrated by drinking plenty of water before your visit can help your body process the dye more easily.
Plan for about 60–120 minutes total, including check-in, pupil dilation, the photography procedure, and a short recovery period. The actual picture-taking usually takes about 10 to 20 minutes, but the preparation and recovery take additional time.
If you are pregnant, breastfeeding, have severe kidney disease, or have had serious allergic reactions to contrast dyes in the past, please discuss alternatives with our retina specialists. We may recommend other imaging tests like OCT angiography that do not require dye injection.
Safety Profile and Side Effects
Fluorescein angiography has been used safely for over 50 years and is considered very safe when performed by experienced professionals like our team at Retina Consultants, PA. We discuss benefits and risks prior to the test and monitor you closely.
Nearly all patients experience these normal, temporary effects after fluorescein angiography:
- Bright yellow or orange-colored urine for 24 to 48 hours as your body eliminates the dye
- Blurred vision and light sensitivity from pupil dilation lasting 4 to 6 hours
- Mild nausea or a warm, flushed feeling during or right after the dye injection
- Slight yellow tint to the skin that fades within a few hours
- Minor discomfort at the injection site, similar to after having blood drawn
Serious systemic reactions are rare, on the order of a few hundredths of a percent; true anaphylactoid events are exceedingly uncommon, and mortality is extraordinarily rare. Our staff is fully trained to recognize and treat these reactions immediately with appropriate medications and emergency procedures.
Patients with a history of severe allergies, asthma, heart problems, or kidney disease may have a slightly higher risk of side effects. We carefully review your medical history and monitor you closely throughout the procedure to minimize any risks.
All of our offices are equipped with emergency medications and equipment to handle allergic reactions or other rare complications. Our staff receives regular training in emergency procedures, and we have protocols in place to ensure your safety at all times.
After your test, drink plenty of water to help flush the dye from your system. Wear sunglasses when outdoors to reduce light sensitivity. You can resume normal activities and eating immediately, though you should not drive until your vision returns to normal.
Fluorescein is excreted in breast milk in small amounts. Many clinicians support continuing breastfeeding without interruption or, if preferred, pausing for 24 hours after informed counseling; in pregnancy, we generally avoid FA unless results would change urgent management, with OCT or OCTA preferred first.
Understanding Your Results
Our board-certified retina specialists carefully analyze your fluorescein angiography images to identify any abnormalities and develop the most effective treatment plan for your specific condition. We integrate findings with other imaging as needed.
Our retina specialists examine hundreds of images from your test, looking for patterns of dye flow that indicate healthy or diseased blood vessels. We compare the timing and intensity of dye appearance in different areas of your retina to identify leakage, regions of poor blood flow, or abnormal blood vessel growth. This detailed analysis takes time and expertise to ensure accuracy.
In healthy eyes, the dye flows smoothly through blood vessels without leaking into surrounding tissues. Abnormal findings may include areas where dye leaks out of vessels, regions with poor blood flow, or new abnormal blood vessels that should not be present. Each pattern helps us diagnose specific retinal conditions.
We often combine your fluorescein angiography results with other tests like optical coherence tomography (OCT) and fundus photography to get a complete picture of your retinal health. This comprehensive approach helps us make the most accurate diagnosis possible.
Based on your results, our retina specialists may recommend various treatments:
- Anti-VEGF injections to reduce abnormal blood vessel growth and leakage
- Laser photocoagulation to seal leaking blood vessels
- Photodynamic therapy for polypoidal choroidal vasculopathy can be used as ICGA-guided therapy, frequently alongside or after anti-VEGF treatment
- For chronic central serous chorioretinopathy, half-dose or half-fluence photodynamic therapy has strong evidence when observation and risk-factor control are insufficient
- Vitreoretinal surgery for complex retinal problems
- Regular monitoring with repeat testing to track changes over time
- Coordination with your primary care doctor for diabetes or blood pressure management
Your follow-up schedule depends on your diagnosis and treatment response. Some conditions require fluorescein angiography every few months, while others may only need repeat testing annually or when symptoms change. Our retina specialists will create a personalized monitoring plan that fits your specific needs.
We believe in clear communication and will explain your results in terms you can understand. We will show you the images, point out any areas of concern, and discuss what the findings mean for your vision and overall eye health. You will receive copies of your images and a detailed report for your records.

Frequently Asked Questions
Our patients often have questions about fluorescein angiography, and our retina specialists want to ensure you have all the information you need to feel comfortable with the procedure. The following answers address the most common concerns.
The actual picture-taking portion of the test takes about 10 to 20 minutes, but you should plan for a total visit time of 60 to 120 minutes to include check-in, pupil dilation, the photography procedure, and a short recovery period.
Most patients find fluorescein angiography to be only mildly uncomfortable. The dye injection feels like a quick pinch, similar to having blood drawn. The bright camera flashes may be startling but are not painful, and any nausea usually passes quickly.
Most patients should not drive for several hours after fluorescein angiography because the dilating drops used to enlarge your pupils cause blurred vision and extreme light sensitivity. Please arrange for transportation home or plan to use public transportation or ride-sharing services.
The most common side effects are temporary and harmless, including bright yellow urine for 1 to 2 days, blurred vision and light sensitivity for 4 to 6 hours, and mild nausea during the injection. Serious allergic reactions are very rare but are promptly treated by our trained staff.
Yes, when medically necessary, fluorescein angiography is typically covered by Medicare and most major insurance plans. Our billing staff will verify your specific coverage and discuss any potential out-of-pocket costs before your appointment.
We generally avoid fluorescein angiography during pregnancy unless it is absolutely necessary for your eye health. When needed, we proceed after counseling if results would change urgent management, and we often use OCT or OCTA as first-line alternatives because they do not require dye injection.
The frequency of fluorescein angiography depends on your specific eye condition and how you respond to treatment. Patients with active diabetic retinopathy or wet macular degeneration may need the test every few months, while others may only need it annually or when symptoms change.
Most patients with kidney disease can undergo fluorescein angiography safely; the dye is renally excreted so clearance may be slower, but it is not nephrotoxic. In advanced kidney disease or dialysis, we individualize timing and consider alternatives when appropriate.
Additional FAQs About Ocular Ultrasound
