# Corneal abrasion

A corneal abrasion is a scratch or loss of surface cells from the cornea, often caused by trauma or foreign bodies. It can be very painful but usually heals quickly.

## Symptoms and causes

People often recall a specific incident.

- Sudden onset eye pain, watering, and light sensitivity
- Blurred vision and foreign-body sensation
- Causes include fingernails, branches, contact lenses, or grit
- Fluorescein staining highlights the epithelial defect

## Management

Treatment aims to prevent infection and relieve pain.

- Topical antibiotic drops or ointment until healed
- Pain control with oral analgesia and sometimes cycloplegic drops
- Bandage contact lenses in selected larger abrasions
- Follow-up to confirm healing and watch for recurrent erosion
