Overview
Recurrent corneal erosion (RCE) is a painful eye condition characterized by repeated breakdown of the corneal epithelium, causing episodes of eye pain, redness, and sensitivity to light. It often occurs after corneal injury or in patients with underlying corneal dystrophies. In Korea, ophthalmologists utilize advanced diagnostics and treatment options to relieve symptoms and prevent recurrences.
What is Recurrent Corneal Erosion?
Recurrent corneal erosion is a disorder where the outermost layer of the cornea (epithelium) fails to properly adhere to the underlying basement membrane, leading to repeated episodes of corneal surface damage. This causes acute pain and discomfort, often upon waking.
Symptoms
- Sudden onset of severe eye pain
- Redness and tearing
- Blurred vision
- Sensitivity to light (photophobia)
- Feeling of a foreign body in the eye
- Episodes often occur in the early morning
Causes
- Previous corneal trauma or injury (e.g., scratches, abrasions)
- Corneal dystrophies, especially epithelial basement membrane dystrophy
- Dry eye syndrome
- Eye surgery complications
Risk Factors
- History of corneal injury
- Underlying corneal dystrophies
- Contact lens wear
- Poor eyelid closure during sleep
Complications
- Repeated corneal abrasions leading to scarring
- Persistent eye discomfort and vision problems
- Secondary infections if corneal surface is compromised
Prevention
- Proper eye protection to avoid trauma
- Treating dry eye conditions
- Avoiding rubbing the eyes
- Using lubricating eye drops as needed
Treatment Options in Korea
Diagnosis
Ophthalmologists diagnose RCE through slit-lamp examination and patient history, sometimes using fluorescein staining to highlight corneal defects.
Medical Treatments
- Lubricating eye drops and ointments
- Hypertonic saline drops or ointments to reduce corneal swelling
- Antibiotic eye drops to prevent infection
- Pain relief medications
Surgical or Advanced Therapies
- Anterior stromal puncture or phototherapeutic keratectomy (PTK) for recurrent cases
- Bandage contact lenses to protect the cornea during healing
Rehabilitation and Support
- Patient education on eye care and injury prevention
- Regular follow-up to monitor healing and recurrence
- Psychological support if chronic pain affects quality of life
