The fluorescein is administered intravenously in intravenous fluorescein angiography (IVFA) and orally in oral fluorescein angiography (OFA). The test is a dye tracing method. The fluorescein dye also reappears in the patient urine, causing the urine to appear darker, and sometimes orange. [2] It can also cause discolouration of the saliva.
A recent trend in the United States is the stand-alone day angiography facility associated with a private vascular surgery clinic, thus allowing treatment of most arterial endovascular cases conveniently and possibly with lesser overall community cost.

[26] OCTA has applications in several diseases, including leading causes of blindness such as glaucoma [24] and age-related macular degeneration. [27]
Red free photography is also regularly used as a base line photo prior to Angiography. [13] Angiography is a process of photographing/recording vascular flow within the retina and surrounding tissue by injecting a fluorescent dye into the blood stream. This dye fluoresces a different colour when light from a specific wavelength (excitation ...
Angiography is also commonly performed to identify vessels narrowing in patients with leg claudication or cramps, caused by reduced blood flow down the legs and to the feet; in patients with renal stenosis (which commonly causes high blood pressure) and can be used in the head to find and repair stroke.
