DRG17478-040303 Strip Opthalmic Fluorescein Strip 0.6Mg 300St/bx
- Fluorescein tear strips are used during an eye test that uses an orange dye (fluorescein) and a cobalt blue light to detect foreign bodies in the eye or damage to the corneal surface. Dye is placed in the eye, using blotting paper impregnated with fluorescein dye, where it stains the tear film which covers the surface of the cornea. The individual is asked to blink to move the dye. A blue light is then directed on the eye, causing the fluorescein to glow green. Abnormalities in the surface of the eye will cause the dye to stain that region. The ophthalmologist or optometrist (eye doctor) can determine the location and probable cause of the cornea problem depending on the size, location, and shape of the staining. This test is useful in superficial scratches or other problems with the surface of the cornea. It can also help reveal foreign bodies on the eye surface. It can be used after contacts are prescribed to determine if there is irritation of the surface of the cornea. Each strip is .6mg.
