    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.

    While conventional dye-based angiography is still the common gold standard, OCTA has been evaluated and used across many diseases. [4] [5] [25] OCTA was first introduced in clinical eyecare in 2014. [26] OCTA has applications in several diseases, including leading causes of blindness such as glaucoma [24] and age-related macular degeneration. [27]

    For example, fluorescent angiography, a technique of analysis of circulation in retina is used for diagnosing various eye diseases. With modern fluorometers, capable of tracking single fluorescent molecules, it is possible to track migrations of single cells tagged by a fluorescent molecule (see fluorescein in biological research ).
