A fluorescein angiogram is an imaging study which allows the doctor to evaluate the circulation, or blood flow, in the retina. This is important in confirming the diagnosis as well as guiding treatment. A fluorescein angiogram is safe and is performed in the office. A small amount of an organic dye, fluorescein, is injected into a vein in your arm.This dye quickly travels to the retina, and photographs are taken for about 10 minutes while the dye circulates through the retina. The dye is safe even in patients with kidney disease including patients on dialysis. The doctor will review risks and benefits of the test with you prior to administration of the test. She will review the test results with you the same day.
