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
