What is Fluorescein Fundus Angiography (FFA)?

Our eyes are delicate, and regular check-ups help keep them healthy. One important test for detecting eye problems is Fluorescein Fundus Angiography (FFA). This test helps doctors examine the tiny blood vessels in your retina and find any issues.



What is FFA?

FFA is an eye test that checks blood flow in the retina. A fluorescent dye is injected into your arm, which travels to the eye. A special camera then takes pictures, helping doctors spot any problems.

Why is FFA Done?

Doctors use FFA to diagnose conditions like:

Diabetic Retinopathy – Retina damage from diabetes.

Age-Related Macular Degeneration (AMD) – A common cause of vision loss.

Retinal Vein Occlusion – A blocked vein in the retina.

Choroidal Neovascularization – Growth of abnormal blood vessels under the retina.

What Happens During the Test?

Your pupils are dilated with eye drops.

A small needle injects the dye into your arm.

As the dye moves through your eye, a camera captures images.

The test takes about 10-15 minutes, but you may stay longer for observation.

After the Test

Your vision may be blurry for a few hours.

Your skin or urine may turn yellow temporarily.

You might feel mild nausea, but it passes quickly.

Avoid driving immediately after the test.

Is FFA Safe?

Yes, it is safe for most people. Rarely, some may have an allergic reaction to the dye. Inform your doctor if you have allergies.

Final Thoughts

If you have blurry vision, floaters, or other eye issues, an FFA test can help diagnose the problem. Early detection is key to protecting your vision. If you have concerns, visit an eye doctor soon!
