Retinal Angiography


Retinal Angiography is a frequently used test that provides valuable information about the eyes' circulatory system, and many conditions that may occur within the back of the eye. Retinal Angiography begins by injecting a special dye into the arm called fluorescein. Within a few seconds, the dye travels through the circulatory system, and into the eye through the retinal vessels, and into a deeper layer called the choroid. A specially equipped camera then captures a series of photographs of the dye as it circulates though the retina and choroid. These photographs can reveal to the doctor signs of circulation problems, swelling, leakage, or abnormal blood vessel formation. This information allows the doctor to make a more accurate diagnosis, and help determine the exact area to be treated for conditions like macular degeneration, and diabetic retinopathy. The dye is considered safe, and serious side effects from the dye are rare.
