What are the risks associated with fluorescein?

The eye test called fluorescein angiography provides an accurate view of the inner eye. Doctors can then check on blood flow and damage. But there are risks. Sterile dyes are injected into your arm's veins. One is an orange-red dye, fluorescein. This dye can make your urine darker and possibly orange or yellow. This may last for a day or two after the test. There may be a mild, brief stinging sensation. Your skin may briefly turn yellow. While rare, infections and allergic symptoms may occur. These include:

• Dizziness
• Faintness
• Dry mouth
• Increased salivation
• Hives
• Increased heart rate
• Metallic taste in mouth
• Nausea and vomiting
• Sneezing
