FFA

Fluorescein angiography (FFA) or Indocyanine green angiography (ICG)


What is Fluorescein angiography/Indocyanine green angiography ?

An angiogram is a diagnostic procedure used in ophthalmology to image the blood vessels of the retina and choroid. It involves inserting a needle into a vein, usually in the arm or back of the hand, and injecting a contrast dye. As the dye circulates through the bloodstream, images of the retina are taken using specialised digital cameras and scanning laser technology. The procedure usually takes around 5-10 minutes, and the results are available immediately. The procedure is safe, with a very low risk of severe adverse reaction

Why is the procedure necessary ?
  • To help the doctor make a diagnosis.
  • To provide guidelines for treatment.
  • To keep a permanent record of the disease process.
Do I have to get admitted for this procedure ?

How is the test performed ?
  • Your pupils will be dilated with eye drops.
  • An injection of yellow dye is given into a vein in your arm.
