Fluorescein Angiography

Fluorescein angiography is the practice of taking photographs of blood vessels inside the eye with the help of a contrast dye. These pictures help doctors evaluate the retina and diagnose and track problems such as diabetic retinopathy, macular degeneration, abnormal vessel growth, swelling, leaking and tumors.

During this exam, the pupils are dilated before photographs are taken with a special ophthalmic camera. The contrast dye is then injected to “light up” the blood vessels for the camera. Once the dye is in place, the doctor will take more photographs, along with a final set about 5 minutes later.
