What are foreign bodies?

A foreign body in the eye is any object that isn’t supposed to be there. The foreign object may be in the conjunctiva. This is a thin membrane that covers the inside of the eyelids and the white of the eye. Or it may be in the cornea. This is the clear, dome-shaped surface that covers the colored part of the eye and the pupil.

What foreign bodies are commonly found in the eye in a child?

The most common foreign bodies in the eye include:

• Dust

What are the symptoms of foreign bodies in the eye in a child?

Symptoms can happen a bit differently in each child. They may include:

• Feeling like there’s something in the eye

• Eye pain, especially when looking at light

• Tearing of the eye

• Blinking a lot

• Rubbing the eye

The symptoms of foreign bodies in the eye may look like symptoms of other eye issues or health problems. Make sure your child sees their healthcare provider for a diagnosis.

How is a foreign body in the eye diagnosed in a child?

Your child’s healthcare provider will ask about your child’s health history. Your child will also have an eye exam. Your child may get local numbing (anesthetic) eye drops for the exam.

Your child’s healthcare provider may also perform 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 special paper strip with a small amount of a dye into your child's eye. This won’t hurt your child. Then, your child’s provider will use a special light to look at the surface of the cornea to look for an abrasion or scratch.

How is a foreign body in the eye treated in a child?

Treatment will depend on your child’s symptoms, age, and general health. It will also depend on how severe the condition is.

Key points about a foreign body in the eye in children

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

• Common foreign bodies in the eye include dirt, dust, makeup, and pieces of metal or rust.

• If your child’s healthcare provider sees a foreign body, they may remove it with a small cotton applicator or saline.

• If your child’s healthcare provider can’t remove the foreign body, if there is a large abrasion on the cornea, if there is a possibility that a foreign body passed into the inside of the eye, or if your child is in a lot of pain, your child may need to see an ophthalmologist. This is an eye healthcare specialist.

• Your child will need follow-up care with their healthcare provider after the foreign body is taken out.
