Fundus Fluorescein Angiography

Fundus fluorescein angiography (retina angiography) is a means of photographing the retina vascular system enabled by enlarging the pupils with drops and then administering up to 5cc fluorescein dye in the arm which is visible in the eye within 8-10 seconds. It is used to aid the opthalmologist in diagnosing retinal diseases and showing the areas to be treated. It has no properties of opening the vessels or treatment. Some patients may feel nauseous during the procedure. Very rarely there may be severe side effects associated with an allergic reaction. For up to 2 days after the procedure, the skin will have a yellow colour and urine will be darker. It is not recommended for use on patients with serious liver or kidney diseases or those who are pregnant.
