Corneal Abrasion

A corneal abrasion is a scratch or injury to the cornea, the clear, protective outer layer of the eye. Abrasions are usually caused by foreign objects like dust, dirt, or fingernails, but they can also result from rubbing the eye too vigorously. While often painful, corneal abrasions are usually minor injuries that heal quickly with proper care.

• Causes: Corneal abrasions can occur due to contact with foreign objects, such as dust, sand, or debris, that scratch the cornea. Rubbing the eyes, wearing contact lenses improperly, or experiencing trauma to the eye can also lead to an abrasion.
• Symptoms: Common symptoms include a sensation of something being stuck in the eye, tearing, redness, sensitivity to light, blurred vision, and discomfort when blinking. The pain can range from mild to severe, depending on the size and depth of the scratch.
• Treatment: Treatment for a corneal abrasion typically involves antibiotic eye drops or ointments to prevent infection, as well as lubricating drops to promote healing and reduce discomfort. In some cases, a doctor may prescribe pain-relieving eye drops or advise wearing an eye patch to protect the eye while it heals. Most corneal abrasions heal within 24 to 48 hours, but larger or deeper abrasions may take longer and require additional treatment.
