A foreign body is any object in your child’s eye that isn’t supposed to be there.

the actual eye. Or it may be in the cornea. This is the clear, dome-shaped surface
that covers the front of the eye.

How is a foreign body in the eye diagnosed?
Your child’s healthcare provider will ask about your child’s health history. He or
she will also give your child an eye exam. Your child may get local numbing (anesthetic)
eye drops for the exam.
Your child’s healthcare provider may also order a fluorescein stain. This test can
tell if there is an abrasion in your child’s cornea. For this test, your child’s healthcare
provider will place a small amount of a dye into your child's eye. This won’t hurt
your child. Then, your child’s healthcare provider will use a special light to look
at the surface of the cornea to see an abrasion or scratch.
How is a foreign body in the eye treated?
Treatment will depend on your child’s symptoms, age, and general health. It will also
depend on how severe the condition is.
Removal of the foreign body
If your child’s healthcare provider sees a foreign body, he or she may remove it.
He or she may use a small cotton applicator to do this. Or he or she may wash your
child’s eye out with saline.
The provider may put an antibiotic ointment in your child's eye.
Evaluation by an eye doctor
If your child’s healthcare provider can’t remove the foreign body or if your child
is in a lot of pain, your child may need to see a specialist. Your child’s healthcare
provider may refer your child to an ophthalmologist or optometrist. These are doctors
with special training to treat eye problems.
An eye patch
If your child has a scratch or injury to the cornea (corneal abrasion), he or she
may need to wear an eye patch. This can make your child more comfortable. Your child
may need to wear the patch for 12 to 24 hours. Your child’s healthcare provider may
use a soft contact lens instead of a traditional patch. Your child may also need an
antibiotic eye ointment.
If your child’s abrasion is severe, your child will need to see an eye doctor. Severe
abrasions increase the risk for eye damage.
Your child may need a tetanus shot after the foreign body is taken out. This depends
on what the foreign body was. It also depends on the vaccines your child has already
Your child will need follow-up care with his or her healthcare provider after the
foreign body is removed.
