A corneal
abrasion is a scratch on the cornea (the clear, nonwhite surface of the
eye). An abrasion can be caused my an eye injury (such as from a
fingernail, a paper cut, a foreign body, or a contact lense).
You may have immediate pain, the feeling that something is in your eye, tearing, or discomfort while blinking.Double click to edit
Your doctor
may use an eye drop that has a special dye to see an area of staining
where the top layer, or epithelium, of the cornea is missing. He or she
may also see redness and inflammation of the eye.
Avoid injury to your eyes. Decrease the length of time you wear your contact lenses.
If you are
experiencing any decrease in vision, redness, severe pain, or a white
spot on the normally clear front surface of your eye, you should
contact your ophthalmologist immediately.
Treatment
usually depends on the size and cause of the abrasion. If it is
small, it can be treated with antibiotic eye drops or ointment.
If it is larger, antibiotic drops, certain dilating drops
(cycloplegics), and rarely pressure patching may be needed. If
organic material (such as grass, plants, or wood) is the cause of the
abrasion, then the abrasion is considered dirty and the eye will need
to be examined more frequently for possible secondary infection.
No pressure patching is recommended for abrasions caused by organic
material or contact lenses.
Corneal
abrasions generally heal in several days, with vision returning to
normal. A secondary infection may make treatment more
difficult. In patients with diabetes mellitus, a corneal abrasion
heals more slowly.
