Corneal Abrasion
The cornea is the
clear front window of the eye. It covers the colored portion
of the eye much like a watch. The outermost layer of the
cornea is called the corneal epithelium.
A corneal erosion or abrasion refers to a scratch or injury
of the corneal epithelium. These painful abrasions occur
quite commonly from vigorous rubbing of the eye after something
has gotten in it, a baby's fingernail, tree limbs, bushes,
or, in some cases, improper removal of a contact lens or
wearing of a torn contact lens. Corneal disease can also
be a contributing factor. NOTE: this is an eye emergency!

TREATMENT
The most common treatment is to patch the eye tightly.
This allows the damaged epithelium to heal. Patching also
reduces the pain by preventing the blinking eyelid from
irritating the affected area. Since both eyes move together
and the eye is most painful when it moves, it is often helpful
to rest the other eye as well.
An antibiotic may be prescribed to prevent infection. Anesthetic
drops can relieve pain and facilitate examination but may
keep the eye from healing properly if used repeatedly.
Occasionally, long after an abrasion has healed; it recurs
spontaneously, often upon awakening in the morning. Recurrent
corneal erosions often require repeat patching or the use
of ointments at bedtime. Sometimes a soft or bandage-type
contact lens is used to facilitate healing.
COMPLICATIONS
If bacteria get into the tissues under the protective corneal
epithelium, infection, or corneal ulcer, can occur. These
complications can be very serious and cause loss of vision.
In the majority of cases, corneal erosions will heal completely.
But proper care and monitoring by you and your eye care
professional are necessary to help prevent serious consequences.
