Corneal Abrasion & Recurrent Erosion Syndrome

What is a Corneal Abrasion?

A corneal abrasion is a scratch or scrape on the surface of the cornea, the clear, dome-shaped window at the front of the eye. The cornea is highly sensitive, so even a tiny scratch can be extremely painful.

Causes

• A fingernail scratch (often from a baby or young child)
• A tree branch or leaf brushing the eye
• Dust, sand, or grit getting trapped under the eyelid
• Aggressive eye rubbing
• Poor contact lens hygiene or wearing damaged lenses

Symptoms

• Severe eye pain or a feeling that something is stuck in the eye
• Tearing and watering
• Redness
• Sensitivity to light (photophobia)
• Blurred vision
• Spasm of the eyelids (difficulty keeping the eye open)

Treatment

Most minor corneal abrasions heal quickly, often within 24 to 48 hours, because the corneal surface cells regenerate rapidly.

• Antibiotic eye drops or ointment: Prescribed to prevent infection while the scratch heals.
• Lubricating drops: To keep the eye comfortable.
• Pain relief: Over-the-counter painkillers (e.g., paracetamol, ibuprofen) can help.
• Do not wear contact lenses until your doctor confirms the eye is fully healed.

Recurrent Corneal Erosion Syndrome

Sometimes, the new cells that heal over the scratch do not anchor down properly. Weeks or months later, these cells can tear off again, usually when you first open your eyes in the morning. This causes a sudden return of the sharp pain and watering.

If you experience recurrent morning eye pain, you may have Recurrent Corneal Erosion Syndrome. Treatment involves intensive lubrication, particularly thick ointments at night, and sometimes specialized procedures to help the cells adhere better.
