What is fluorescein angiography?


This common test of the retina involves an injection of fluorescein dye usually in a vein in the arm.  The dye circulates to the retinal blood vessels, which are photographed, in order to detect abnormal blood vessel growth or leakage in disorders such as age-related macular degeneration or diabetic retinopathy.
