What is fluorescein angiography?

For a very accurate eye exam, your doctor may give you an eye test called fluorescein angiography. An orange-red dye called fluorescein is a sterile dye that is injected into the arm's veins. This dye help provide a clearer picture of the eyes’ interior. The test then quickly photographs the inner eye. Your eye doctor uses this test to examine the eye’s retina, cornea and choroid. The photographs act like a “map.” Doctors use them to check on these regions’ blood flow. They also look for any damage or foreign bodies.
