Fundus Florescein Angiography

Fluorescein angiography is an extremely valuable test that provides clinical information about the circulatory system of the ocular fundus (the back of the eye) not attainable with a routine examination. The test is performed by injecting a special dye called sodium fluorescein into a vein in the arm. In few seconds, the dye travels to the blood vessels inside the eye. A camera equipped with special filters that highlight the dye is used to photograph the path of the fluorescein as it circulates though the eye.
