• A corneal abrasion is a simple scratch limited
to the corneal epithelial surface.
• A corneal or conjunctival foreign body is irritating, and rubbing
may lead to further abrasions.
• Suspect an embedded eyelid foreign body when no object can be
visualized and symptoms are persistent.
• Copious irrigation and mechanical removal of a persistent foreign
body is necessary to prevent further abrasions.
• If possible, do not apply a topical ophthalmic anesthetic until
a foreign body is visualized or you are confident that none is present.
• Patients can help localize a foreign body but sensation will
be eliminated by the topical anesthetic.
• Patient’s inability to feel increases the potential
for abrasions since there is no further pain or apprehension with blinking,
eye movement, or rubbing.
