Corneal abrasion

Corneal Abrasion is a medical condition that involves the scratching or scraping of the cornea, the clear, protective layer covering the front of the eye. This condition is often caused by foreign bodies, such as dust or sand, but can also result from physical trauma or improper use of contact lenses.

Causes

Corneal abrasions can be caused by a variety of factors. These include:

• Foreign bodies: Dust, sand, and other small particles can scratch the cornea if they become trapped under the eyelid.
• Physical trauma: A direct blow to the eye, such as from a fist or ball, can cause a corneal abrasion.
• Improper use of contact lenses: Wearing contact lenses for too long, or not cleaning them properly, can scratch the cornea.

Symptoms

The symptoms of a corneal abrasion can vary depending on the severity of the injury. Common symptoms include:

• Pain and redness in the eye
• Sensitivity to light
• Blurred vision
• Feeling like there is something in the eye

Treatment

Treatment for corneal abrasions typically involves removing any foreign bodies from the eye and using medicated eye drops to prevent infection and promote healing. In some cases, a patch may be used to protect the eye while it heals.

Prevention

Preventing corneal abrasions involves taking steps to protect the eyes from injury. This can include wearing protective eyewear when participating in sports or doing work that involves flying particles, and following proper hygiene practices when using contact lenses.
