Testing & Diagnosis for Foreign Bodies in the Eye in Children

How is a foreign body in the eye diagnosed?

Diagnosis is usually made after a complete physical examination of your child's eye.

  • Local anesthetic drops in the eye may be used in order to examine your child.
  • In addition, your child's physician may also order a fluorescein stain to help confirm the diagnosis and evaluate if there is an abrasion to the cornea. A fluorescein stain is done by placing a small amount of a dye in your child's eye. This does not hurt.
  • A special light is then used to look at the surface of the cornea to see any abrasion or scratch.
