what color does an area of trauma show up in a corneal abrasion with fluorencein dye? clear or yellow?
927379
hey i know this answer b/c i took medical terminology.  a trauma in a corneal abrasion shows up yellow with fluorencein dye under light.  A way to clearly understand this is to know that fluorin- is a root word for yellow, and a corneal abrasion would cause the dye to collect in the abrasion thereby showing the entire area of trauma.

When the bilirubin level gets high enough, the yellow color shows up in most visible areas--skin, urine, mucus membranes, etc; it's not just the sclera that turns yellow.

First of all, I experienced this problem recently with my child.  It is very painful!  The treatment we gave her is basically the same as it would be for anyone.\n\nWhen you scratch the cornea it makes your eye very sensitive to light, there is pain varying in the degree of the scratched area, and a lot of uncontrollable tears.\n\nWe had no idea what was wrong with her so we took her to the emergency room.  They evalutated her and found it to be an issue with her eye.\n\nTo confirm the problem a special dye was put in and the room lights were turned out while a black light was hovered over the eye.  It clearly shows the depth of the cut.  Everything shows up a fluorescent green color.  We could see how badly her eye was cut.\n\nHer treatment included: an antibiotic to apply to the eye, an eye patch to protect the eye, however, in our case our child was too small to tolerate the eye patch so we kept her in a darkened room for about 24 hours and she was able to tolerate light once again. She was also given medication to help relieve the pain.\n\nWe were told she shouldn't rub the eye as this would only aggravate the pain and healing process.  The doctor said the cornea is the fastest healing area of the body and only takes a day or two to heal.  That is the good news!\n\nThis was my personal experience and the treatment is the general treatment for anyone with a cornea scratch.

Im not sure if your talking about the type of light or the color of the pain on the inside of the glass.  \n\nIf you talking about the light being produced then its because all wavelengths of light are present.\n\nIF your taling about the color of the paint then, its because white does not absorb any wavelengths of light, therefore all wavelenths are given off

Mine is naturally clear. I do, however, drink lots of water daily, which will dilute it. If I cut down on my water intake, I make less trips to the toilet, & my wee is stronger & more concentrated, which makes it a more yellow colour.

If you busted a blood vessel in your eye itself it would look very bloody in most cases.  If you busted one in the area around your eye it would look like a bruise.  If it is just red and swollen then it may just be irratation from the crying.  Try using warm compresses over night.  If you wear contact lenses I sugest you take them out until tomorrow morning.  If it still doesn't seem any better tommow, contact your eye doctor.

Cheerful sunny yellow is an attention getter. While it is considered an optimistic color, people lose their tempers more often in yellow rooms, and babies will cry more. It is the most difficult color for the eye to take in, so it can be overpowering if overused. Yellow enhances concentration, hence its use for legal pads. It also speeds metabolism.\n\n(see link for more interesting info re colors)

See your eye doctor ASAP.\n\nDon't want to alarm you, but if the redness and pain are persistent, you should seek consult as soon as possible.  Wearing contact lenses (especially longer than you're supposed to!) predisposes one to corneal ulcers, especially those caused by a parasite called Acanthamoeba or a bacteria called Pseudomonas, which can be very virulent.\n\nOf course, it can be something totally benign, but to be on the safe side, seek consult.  Don't self-medicate.  Stop wearing the contacts.  See your doctor.

See if these fit\n\n1) bright field\n\n2) cilia\n\n3) contrast? = staining

You need to see an Opthalmologist,not an Optometrist.\n    An optometrist can not treat the injury as an Opthalmologist can.\n    You could have some serious problems either with your corneal or your the iris of your eye.\n    Either way you could have an infection /inflammation that left untreated could cause some serious problems down the road.\n    Should there be nothing wrong,it is better to be safe than it is to be sorry......We only get 2 eyes and we have to protect them.

usually a stain or paint.\nHehehe, just kidding.\nI think it depends on the fluids inside the organ (ie. melanin, bile, urea, amount of blood flow to the organ, etc)\nAre you thinking of one particularily?

Any substance appears coloured because it absorbs all other wavelengths of the visible spectrum other than the wavelength of its colour.i.e if a substance is blue in colour then it absorbs all other wavelenths of the visible spectrum  including red,orange yellow, green  except those pertaining to the blue region of the spectrum. Hence when these wavelenths strike the retina of the eye ,we perceive it as a blue coloured substance.\n   Now though it absorbs all other wavelenths ,it absorbs maximally those of  a coloured region complementary to its physical colour.Thus for blue the complementary colour is orange(oppt ends of the spectrum),for violet  eg KMnO4 it is red etc.So if you have to study the absorption power of a blue solution you have to use  an orange filter in the colorimeter and for an orange coloured solution eg K2Cr2O7  you will use a blue filter.

You should go to the ER. It could be a simple conjunctivitis, but then it better not be taken for granted. Some types of conjunctivitis can affect the cornea too leading to corneal opacities and vision problems later on. It is your eye! Please be serious about it, visit the ER! \n\nI am against trying self medication for the eye!

The flash is the problem. The eye's retina contains a crisscross of red blood vessels. Sometimes, when the light from a camera flash reflects off the retina it bounces back to the camera lens carrying a red tint from the blood vessels and from a brownish pigment in a few layers of the retina.

Shure you should see an eye doctor!!i dont think it is connected with that reddish spot above your eyelid!!you may have problems with the lacrimal system,for example-obstruction of the lacrimal canalliculus!!

It's a fairly recent bruise.  Red is most recent, then it turns blue..   As the bruise ages, it will fade to light purple-ish green and finally yellow.

It sounds like a pterigium or a pingueculum but without a visual, it is impossible to diagnose. See your local Ophthalmologist.
