This is a test that uses orange dye (fluorescein) and a blue light to detect foreign bodies in the eye. This test can also detect damage to the cornea, the outer surface of the eye.
How the test is performedA piece of blotting paper containing the dye will be touched to the surface of your eye. You will be asked to blink. Blinking spreads the dye around and coats the "tear film" covering the surface of the cornea. (The tear film contains water, oil, and mucus to protect and lubricate the eye.)
A blue light is then directed at your eye. Any problems on the surface of the cornea will be stained by the dye and appear green under the blue light.
The health care provider can determine the location and likely cause of the cornea problem depending on the size, location, and shape of the staining.
How to prepare for the testYou will need to remove your contact lenses before the test.
How the test will feelIf eyes are extremely dry, the blotting paper may be slightly scratchy. The dye may cause a mild and brief stinging sensation.
Why the test is performedThis test is useful in identifying 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.
Normal ValuesIf the test result is normal, the dye remains in the tear film on the surface of the eye and does not adhere to the eye itself.
Note: Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.
What abnormal results meanAdditional conditions under which the test may be performed:
What the risks areIf the fluorescein touches the skin surface, there may be a slight, brief, discoloration.
Special considerationsThis test is very useful for detecting injuries or abnormalities on the surface of the cornea.

In the eye, everythng is still, there's almost no wind. Surrounding the eye is the eye wall, which has the strongest winds in the hurricane.
The eye of a hurricane is calm and often relatively clear of clouds.

An ultrasound or a fluorescein angiography are two tests doctors use to further diagnose eye cancers. In an ultrasound sound waves are pointed at the tumor and depending on how they reflect off the tumor the doctor can.
Try and oil-free eye make-up remover on the stain and it should come right out!
Start by removing as much of the stain as you can by scraping or blotting. Do not rub.If the stain is lipstick or eye-makeup, use a pretreatment. These can be found anywhere you buy detergent, and have directions on the back.After you've completed the pretreatment, or if the stain was caused by foundation, rub the stain with a bit of your liquid detergent. Rinse.Wash the clothing as you normally would.
Remove Eye Liner by following these steps:Sponge with Drycleaning Solvent.Sponge with Dry Spotter.Keep stain moist and blot occasionally with Absorbent Material.Continue as long as stain is being removed.Flush with Drycleaning Solvent.Repeat above steps until no more stain is removed.Allow to dry completely.Sponge with water.Apply Wet spotter and a few drops of Ammonia and Sponge.Keep stain moist and blot occasionally with Absorbent Material.Continue as long as stain is being removed.Flush with water.Repeat above steps until no more stain is removed.See related link for more specifics
You can an electrophoresis gel and then stain the gel using a solution such as coomassie blue to make the bands visible. Alternatively, you can stain a cell containing DNA by using acridine orange. It is necessary to observe these under an electron light microscope.
Tear stain is very common in dogs and you can wipe this away yourself with a tissue or gauze wet with slightly warm water and use this to wipe away the tear stains. However if your dog is having discharge from the eye, crusty sleepers around the eye or his eyes looked red rimmed then you will need to make a Vet appointment.
