Fluorescein is used to help in the diagnosis of a number of eye problems. [3] When applied as a drop or within a strip of paper to the surface of the eye it is used to help detect eye injuries such as foreign bodies and corneal abrasions .
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 2% [2] is instilled into the lower fornix of patient's eye. Alternatively, impregnated fluorescein strip moistened with preservative (benzalkonium chloride) free saline solution can also be used. [6] The eye is examined under a slit lamp with a low magnification and a broad beam covering the whole cornea. The lamp is switched to a ...
A fluorescein strip containing 10% fluorescein is applied topically to the affected area, without applying pressure on the eye due to the risk of tissue extrusion. [2] The fluorescein is examined with a cobalt blue filter. At this point, the fluorescein appears green in color.
After five minutes, the patient is asked to open both eyes and look upward so the test strips may be removed. The Schirmer test score is determined by the length of the moistened area of the strips (using the scale packaged with the strips) The use of the anesthetic ensures that only basal tear secretion is being measured.

Similar in size, shape and thickness to a postage stamp, thin-film strips are typically designed for oral administration, with the user placing the strip on or under the tongue (sublingual) or along the inside of the cheek (buccal). These drug delivery options allow the medication to bypass the first pass metabolism thereby making the ...
We’ve all seen or used the classic pore strip before, which promises to draw out both blackheads and whiteheads along the T-zone, but the These Oil-Absorbing Pore Strips Show a Visible ...
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.
