Why is a scratched cornea serious

In the eye, the top layer of the cornea is covered by a layer of cells called the corneal epithelium. An abrasion occurs when this layer is disturbed and cells are lost. A corneal abrasion — also known as a scratched cornea or scratched eye — is one of the most common eye injuries.

Scratched cornea symptoms might include significant discomfort, red eyes, tearing, blurry vision and sensitivity to light. Anything that makes contact with the surface of the eye can cause a corneal abrasion. However, it is less common for a corneal abrasion to occur from a traumatic event like getting poked in the eye compared to everyday circumstances that lead to abrasions.

Dry eyes and the improper use of contact lenses can increase the risk of corneal abrasions. Those who experience dry eyes at night can actually tear the corneal epithelium when opening the eyelids because of the lack of moisture in the eye.

Damaged contact lenses or wearing them too long also increases the risk of a scratched cornea. During IPL, concentrated light energy reduces inflammation and acts as a warm compress to restore proper function to tear-producing glands and encourage increased tear flow.

It is usually a good idea to be evaluated by a doctor to get a professional medical opinion on your injury. Sometimes, the doctor may refer you to an ophthalmologist or similar specialist if your injury seems serious. A mild corneal abrasion will generally heal in one or two days, which is why it is recommended to be reevaluated by a doctor after 24 hours for such injuries. Again, a mild corneal abrasion may not need treatment other than observation.

A severe corneal abrasion can take three days or slightly longer to heal. While it is a good idea to see a doctor for any corneal abrasion, a severe corneal abrasion could lead to permanent damage.

It is likely that you will need to go to an ophthalmologist to deal with a severe corneal abrasion, especially if foreign bodies need to be removed from your eye. Additionally, your risk of further complications is linked to the severity of the injury. Sight can be permanently damaged if the corneal epithelium scars heavily. Deep scratches can cause it to be necessary to receive a corneal transplant for improvement. It is also possible for deep scratches to become infected, which is why topical antibiotics are sometimes prescribed.

Keeping fingernails, particularly the fingernails of children and infants, short can reduce the likelihood of scratching the eyes if they are rubbed or accidentally touched. People who engage in any activity where there is a risk of debris or eye injury should wear protective eyewear. It should be noted that regular eyewear does not provide sufficient protection.

January 15, What Is Corneal Abrasion? For example, sand and dust getting into your eye could lead to abrasion, as well as debris from an industrial workplace. Makeup brushes can cause scratches as well, along with incorrectly removing a contact lens. Even dry eyes can be to blame. If your eyes get dry while sleeping, opening your eyelids in the morning can lead to abrasions due to the lack of moisture and the increased amount of friction.

Essentially, anything that touches the cornea directly can damage the delicate tissue. Mild abrasions may only produce mild symptoms, such as a general feeling of discomfort. The more severe the abrasions tend to be, the more noticeable symptoms often are. However, even a mild scratch can evolve into a more dangerous condition if not properly treated. Some cases require a patch to prevent the eye from moving within the eyelid.

This way new cells can reconnect to undamaged cornea layers during the healing process. If you happen to wear contact lenses and have a corneal abrasion, you may need to refrain from contact use for at least 24 hours after diagnosis and treatment. The aftermath of a corneal abrasion can range from the simple to the complex.

Checking with an eye doctor is important regardless of the severity due to the issues a damaged cornea can present.
