Corneal Abrasion (“Scratched Eye”) | Causes, Signs & Symptoms, Diagnosis, Treatment

A corneal abrasion is a disruption (abrasion, scrape, or scratch) of the cornea, the transparent front layer of the eye. This can occur by a variety of causes, including getting debris in the eye, rubbing of the eye, and contact lens use. When the cornea has become damaged, there are several signs and symptoms that can occur, including eye redness, eye tearing, photophobia and blurry vision. In this lesson, we will discuss in more detail the signs and symptoms of a corneal abrasion, complications from a corneal abrasion and how it’s diagnosed and treated by clinicians.

VIDEO TRANSCRIPT

Cuts and scrapes are a part of childhood. In most cases, they’re not serious and can be treated at home.

If the wound is bleeding, press sterile gauze or a clean cloth firmly on it until the bleeding stops.

Hold the area under cool, gentle running water. You can also use bottled water or saline wound spray.

Remove any debris by rubbing gently with a clean cloth or use clean tweezers.

Don’t apply any cleaning or disinfecting solutions to the wound. They don’t help and will only cause pain.

Use a bandage to cover the wound until a scab has formed. An antibiotic ointment will help keep the bandage from sticking to the wound.

You can use a Steri-strip or butterfly bandage to pull the edges of a superficial cut closer together. Don’t use ointments as they’ll prevent the bandage from sticking to the skin.

Change the dressing every day or more often if it gets wet or dirty.

Once a cut or scrape has formed a scab, you can leave it open to the air. If the scrape is in an area that’s likely to get irritated or dirty, keep it covered.

• When your child cuts or scrapes themself, hold the wounded area under cool water and remove any debris with a cloth or tweezers.
• Cover the wound with a bandage and ointment until a scab has formed.
• Change the dressing every day or more often if it gets wet or dirty.

The Wyzenbeek test is an abrasion test that tests a fabric’s ability to withstand surface wear from rubbing. In this test, the fabric is pulled taut and rubbed in both the warp and filling directions, using a piece of cotton duck fabric as the abradant. The number of cycles, or “double rubs”, endured before the fabric shows “noticeable wear” is counted and determines the fabric’s abrasion rating.
