Fluorescein angiography is used to gain information about the circulation in the retina, the light sensitive tissue at the back of the eye. It is useful in the investigation of many conditions including diabetic retinopathy, age-related macular degeneration and retinal vein occlusion.
Prior to the test your vision will be measured and then drops will be put in your eyes to dilate your pupils.
A small needle will be placed into a vein in your arm or hand. You will then sit at a special retinal camera, and have several photographs taken of your eyes before, during and after injection of the fluorescein dye into your vein.
Are there any side effects?
It is common to notice a yellow tinge to the skin and a bright green/yellow staining of the urine for 24 – 48 hours after the test.
Some people feel brief nausea during or just after injection of the dye.
Occasionally some patients have an allergic reaction to the fluorescein dye, and in extremely rare cases this can be a serious allergic reaction known as anaphylaxis. It is very important to let your doctor know of any allergies you have prior to the test and also to let the staff know as soon as possible if you feel unwell during or after the procedure.
