A corneal abrasion is a scratch on the cornea. The cornea is the clear, front surface of the eye. It is located directly in front of the colored part of the eye.
The cornea has several layers that help protect the eye.
Most corneal abrasions happen as a result of:
Risk Factors TOP
Factors that may increase the risk of corneal abrasion include:
Symptoms may include:
You will be asked about your symptoms and medical history. An eye exam will be done. The doctor will look for any foreign objects in the eye. Drops may also be placed in the eye for comfort. They can also make the scratch more visible under a special light.
Minor scratches usually heal within 1-2 days. Some severe corneal abrasions may form a scar and permanently impair vision. An eye specialist may be needed to treat large or deep scratches.
Treatment may include:
Removing a Foreign Object
The foreign object may be removed. This may be done by flushing the eye with saline or by using a cotton swab, needle, or other tool.
Medications may include:
Eye problems should always prompt a visit to an eye doctor right right. Other self-care steps:
In some cases, a contact lens will be placed in the eye to help relieve the discomfort and improve healing.
The eye will be monitored on a regular basis to make sure the scratch is healing.
Prevention aims to avoid injury to the cornea. To avoid injuring the cornea:
If something gets in the eye:
If an object strikes the eye at a fast pace, it can be a medical emergency. Seek medical attention right away.
If a chemical splashes into the eyes, flush them right away and call for emergency medical services.
If there is no eye pain or a foreign object, consider seeing an eye specialist immediately rather than going to the emergency room. However, for a severe injury or chemical splash, call for emergency medical services.
