Why It Is Done

An eye angiogram is done to:

• Confirm the presence of abnormal blood vessels in or under the retina.
• Check for and locate leaking blood vessels in the retina, especially if you have symptoms that suggest damage to or swelling of the retina, such as blurred or distorted vision. This is often caused by diabetic retinopathy or macular degeneration.
• Help find inflammation or tumors in the eye.
• Locate the precise areas of the retina that need treatment prior to laser eye surgery.
• Help find blockage in the blood vessels that feed or drain blood from the retina (retinal arteries and veins).
