Since two medical students uncovered the potential of fluorescein to help diagnose and guide treatment of retinal conditions, fluorescein angiography has become an invaluable tool in retina care.
A dye, called fluorescein (which is different from other contrast dyes) is injected into a vein of the arm and photographs, using special filters, are taken of the back of the eye. No x-ray or radiation is used.
We have the latest digital imaging system so the photographs are instantly available and special computer programs so that these digital pictures can be enhanced.
Overall, the test is very safe with side effects ranging from brief nausea during the test itself to slight allergic reaction. About 1 in 200,000 people will experience a serious or even life-threatening reaction. We have special equipment in our office for such emergencies and our office is located close to University Hospital. Nevertheless, you should always discuss all the risks and alternatives with your doctor to make an informed decision before you proceed with the test.
The other dye, indocyanine green or ICG, angiography uses the same principle as fluorescein angiography, only in the case of ICG, the dye leaks from more areas in the eye. In certain circumstances, ICG angiography can aid diagnosis of retinal conditions.
As with fluorescein angiography, we have special digital equipment to capture the ICG images. And, as with fluorescein angiography, you should discuss the test, its alternatives, and it risks thoroughly with your doctor before proceeding with the test.
