What is FFA?

This is a diagnostic test whereby special photographs are taken of the eye to give the doctors more information about the condition of the back of the eye and to decide on the best form of treatment.

Fluorescein is a yellow dye injected into a vein in the arm or hand. The dye travels in the blood stream to the eye and photographs are taken during its passage through the eye’s circulation. The test demonstrates abnormalities in retinal blood vessels and aids in diagnosis and treatment of many eye conditions, especially macular degeneration, diabetic retinopathy, retinal vein blockages.

Photos are taken with a special camera and processed digitally onto computer. Results are available immediately.

Associated risks with FFA

Fluorescein angiography may be associated with any of the following risks:

• Yellow colour change of skin and urine – this affects everyone and lasts 24 hours.
  
• Nausea – may develop 30 seconds or so after injection, but often passes quite quickly.
  
• Vomiting – rarely follows nausea and again resolves quickly.
  
• Fainting or dizziness
  
• Temporary dazzling
  
• Temporary rose coloured vision
  
• Allergy reactions: These are very rare. The most common allergy reaction is an itchy skin rash known as hives. In very exceptional circumstances severe and life threatening allergy reactions can occur resulting in hospitalisation or even rarely in death.  (Risk less than 1 in 50,000).

You must not have fluorescein angiography if you are pregnant – please tell your Doctor.

Please inform your Doctor if you have had any reaction to fluorescein angiography on a previous occasion.
