An angiogram is a photographic test performed to examine the retina at the back of your eyes using a special camera and taking multiple photographs, coupled with a small injection of a special dye into a vein in your arm. This test provides your Doctor with necessary information about the retina and nearby tissues and is used to diagnose certain eye conditions, determine if treatment is possible, and plan or guide your treatment.
Most patients who undergo a angiogram do not experience significant side effects. About one patient in twenty patients may feel a little nauseous or light-headed for about 20 seconds as the dye circulates. The nausea is very rarely enough to cause vomiting. In all cases, the dye eventually gets excreted through the kidneys, so you will pass bright orange/yellow urine during the next 24 hours or more. Approximately one in 200 0000 people may experience an anaphylactic reaction to this water soluble vegetable dye and 1:20 000 people may have an allergic reaction.
