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.
The most common angiographic techniques were fluorescein (FA) or indocyanine green angiography (ICGA), which both involve the use of an injectable dye. Intravenous dye injection is time-consuming and can have adverse side effects.
[7] [3] When used by mouth or injection, side effects may include headache, nausea, and a change to the color of the skin for a brief period of time. [3] Allergic reactions may rarely occur. [3] Fluorescein is a dye which is taken up by damaged cornea such that the area appears green under cobalt blue light. [3]

The use of fluorescein amidite, shown below right, allows one to synthesize labeled oligonucleotides for the same purpose. Yet another technique termed molecular beacons makes use of synthetic fluorescein-labeled oligonucleotides. Fluorescein-labelled probes can be imaged using FISH, or targeted by antibodies using immunohistochemistry.
Fluorescein is an FDA-cleared dye that is used in ophthalmology clinics in routine as it appears green under cobalt blue light. [12] It is commonly applied topically to identify corneal diseases with slit lamp microscopes including corneal abrasion , ulcers , and infections ; or intravenously to identify retinal diseases with angiography ...

The reports are peer-reviewed by medical experts in the particular drug category. Best Buys are then chosen based on a drug’s effectiveness and safety, the side effects it may cause, how convenient it is to use, its track record in studies and use over time, and how much it costs relative to other drugs.
