fluorescein

 [floo͡-res´ēn]
a fluorescing dye; the sodium salt is used as a contrast medium in retinal angiography and as a diagnostic aid for revealing corneal lesions and fitting contact lenses.

fluor·es·ce·in

(flōr-es'ē-in), [C.I. 45350]
An orange-red crystalline powder that yields a bright green fluorescence in solution and is reduced to fluorescin; a nontoxic, water-soluble indicator used diagnostically to trace water flow.

fluorescein

(flo͝o-rĕs′ē-ĭn, flô-, flō-)
n.
An orange-red compound, C20H12O5, that exhibits intense fluorescence in alkaline solution and is used in medicine for diagnostic purposes, in oceanography as a tracer, and as a textile dye.

fluor·es·ce·in

(flōr-es'ē-in)
[C.I. 45350] An orange-red crystalline powder that yields a bright green fluorescence in solution, and is reduced to fluorescin; a nontoxic, water-soluble indicator used diagnostically to trace water flow and to visualize corneal abrasions or ulcers.

fluorescein

A green dye that fluoresces bright yellow in blue or ultraviolet light. It is used to tag (label) and thus show up ANTIBODIES in tissues. It is also much used by eye specialists (ophthalmologists) to show up ulcers on the cornea and to delineate for photography the blood vessels of the retina. For the latter purpose, the due is injected rapidly into the bloodstream (fluorescein angiography). The drug is on the WHO official list. Brand names are fluorescein, Minims fluorescein, Minims lignocaine (lidocaine, a local anaesthetic) and fluorescein, and Minims proxymetacaine (a local anaesthetic) and fluorescein.

Fluorescein

A brand name for FLUORESCEIN.

Fluorescein

A fluorescent chemical used to examine the cornea.
Mentioned in: Corneal Ulcers

fluorescein

A fluorescent, weak dibasic acid with a molecular weight of 376 whose sodium salt is used in dilute solution as a dye in the fitting of contact lenses, in the detection of corneal abrasions, etc. It is a yellowish-red compound, which fluoresces a brilliant yellow-green under ultraviolet or blue illumination (Fig. F7). Syn. sodium fluorescein. See fluorexon; Burton lamp; Wood's light; rose bengal; staining; break-up time test; fluorescein test.

The visualization set-up requires the utilization of fluids which are transparent and able to solubilize the fluoresceine marker.
These two model fluids are hydrophilic which allows the dissolution of small amounts of fluoresceine that does not modify their viscosity.
