What can cause abnormal fluorescein test results?

Fluorescein angiography is an eye test. It checks blood flow, damage and foreign bodies in the retina, choroid and cornea. The resulting pictures then map the locations for possible treatment. Abnormal results may be due to:

• Blood flow problems (blockage of the arteries)
• Cancer or tumors
• Retinopathy (damage to the retina’s blood vessels)
• High blood pressure
• Swelling (edema)
• Macular degeneration (the part of eye enabling fine detail; you gradually lose sharp, central vision) 
• Micro aneurysms (enlarged capillaries in the retina)
