Fluorescein Angiography

Fluorescein Angiography (FA) is an investigation to further investigate the cause of the retinal disease. In this 3ml of a water soluble fluorescent dye is injected into a vein on the patient's arm. As the dye reaches the blood vessels of the retina ( It takes only 10sec !! ) , sequential photographs are taken using a sophisticated digital camera. The abnormal leakage of dye or absence of normal pattern of dye gives the doctor clues regarding the diagnosis and severity of the retinal disease.
This test is simple with generally no significant side-effects.
