About this service
Fluorescein angiography is a diagnostic procedure which photographs the retina - the light-sensitive tissue at the back of the eye.
This test is used to diagnose certain eye conditions, and to determine and plan treatment.
Common conditions requiring fluorescein angiography include macular degeneration, diabetic retinopathy and retinal vascular disease. In some cases, the angiography may be repeated to monitor your response to treatment or changes in an eye condition.
This test takes only a short time, causes little discomfort and needs no special preparation.
A dye is used to highlight the blood vessels at the back of the eye. The dye is usually injected into a vein in your arm or hand. Your eyes will be dilated with eye drops and you will be seated in front of a special camera.
A few seconds later, as the dye reaches the vessels at the back of your eye, a series of photographs are taken.
There is no permanent effect on your vision from having the test done.
Following the procedure
Once the procedure is complete, you can go back to normal daily activities.
Sometimes the dye makes your skin look yellow, and your urine may be orange in appearance for a day or two after the test. These effects are temporary and harmless.
