7.1 Color Fundus Photography


Fluorescein angiography (FA) is an imaging technique in which a fluorescent dye is used to highlight features of the retinal vasculature. A series of black-and-white fundus photographs, taken as sodium fluorescein dye fills the retinal vessels, helps to document vascular leakage and other abnormalities.
