Fluorescein angiography is a medical procedure used to visualize the blood circulation in the retina of the eye. It involves the injection of a fluorescent dye that allows the doctor to see the blood vessels in the retina in order to diagnose conditions such as macular degeneration or diabetic retinopathy. Synonyms for fluorescein angiography include retinal fluorescein angiography, fundus fluorescein angiography, and retinal angiography. In addition to fluorescein angiography, there are other imaging techniques used to examine the eye, such as optical coherence tomography, magnetic resonance imaging, and ultrasound. These techniques can provide a more detailed view of the eye's structures and help to pinpoint the location and extent of any abnormalities.
