Instructions for Fundus
Fluorescein Angiography
Fundus fluorescein angiography (FFA) is a diagnostic test that uses a special camera
and a fluorescent dye to examine the blood flow in the retina at the back of the eye. The
procedure involves injecting a small amount of a fluorescent dye into a vein in the arm,
which then circulates through the bloodstream and into the retina. The camera takes a
series of pictures as the dye passes through the blood vessels in the eye.
Here are some general instructions for undergoing an FFA:
- Before the test, avoid eating or drinking for a few hours.
- You will be asked to sign a consent form that explains the procedure and its risks.
- Eye drops will be instilled in your eyes to dilate the pupils to allow the camera to get a clear view of the retina.
- A small needle will be inserted into a vein in your arm to inject the dye. You may feel a brief sting or discomfort when the needle is inserted.
- You will be seated in front of the camera and a series of pictures will be taken as the the dye flows through the blood vessels in your retina. You may be asked to look in different directions during the procedure.
- After the procedure, you may experience some mild side effects, such as temporary blurriness or sensitivity to light. These should resolve within a few hours.
- Your doctor will review the images to assess the blood flow in your retina and diagnose any conditions or diseases that may be present.
