What Is a Corneal Abrasion?

This post was written with Consensus AI Academic Search Engine – please read our Disclaimer at the end of this article. A corneal abrasion is a superficial injury to the cornea, the clear, dome-shaped surface that covers the front of the eye. This type of injury typically involves the loss of the corneal epithelium, the outermost layer of the cornea, which can result from various causes such as trauma, foreign bodies, or mechanical damage2 6 9.

Causes

Corneal abrasions can occur due to several reasons, including:

• Trauma: Direct injury to the eye, such as being poked by a finger or struck by an object, is a common cause2 6.
• Foreign Bodies: Particles like dust, sand, or metal shavings can get into the eye and scratch the corneal surface10.
• Mechanical Damage: Activities that involve rubbing the eyes vigorously or improper use of contact lenses can also lead to corneal abrasions9.

Symptoms

The symptoms of a corneal abrasion can be quite pronounced and may include:

• Pain: A significant amount of pain is often reported, which can be severe and persistent1 5.
• Redness: The affected eye may appear red and inflamed6.
• Tearing: Increased tear production is a common response to the irritation caused by the abrasion10.
• Photophobia: Sensitivity to light is frequently experienced by individuals with corneal abrasions6 10.
• Foreign Body Sensation: A feeling that something is in the eye, even if the foreign body has been removed, is typical10.

Diagnosis

Diagnosing a corneal abrasion typically involves:

• Patient History: Understanding the circumstances leading to the injury can provide clues2 3.
• Visual Inspection: An eye examination using a slit lamp can help visualize the abrasion8.
• Fluorescein Staining: Applying a fluorescein dye to the eye can highlight the abrasion under blue light, making it easier to see5 8.

Complications

While most corneal abrasions heal without long-term issues, complications can arise, such as:

• Infection: If not properly managed, an abrasion can become infected, leading to more severe eye problems10.
• Recurrent Corneal Erosion: Some individuals may experience repeated episodes of corneal abrasions due to incomplete healing of the corneal epithelium7.

Conclusion

Corneal abrasions are a common ocular injury that can result from various causes, including trauma, foreign bodies, and mechanical damage. Symptoms are typically severe and include pain, redness, tearing, photophobia, and a sensation of a foreign body in the eye. Proper diagnosis and management are crucial to prevent complications such as infection and recurrent corneal erosion.
