What is Recurrent Corneal Erosion (RCE)?

RCE is an eye condition where the outer layer of the cornea, the epithelium, fails to heal correctly after damage. This can cause repeated pain episodes, primarily upon waking, blurred vision, and light sensitivity.

What causes RCE?

RCE can result from:

• Eye Injuries: Such as scratches or chemical damage.
• Corneal Dystrophies: Genetic conditions like map-dot-fingerprint dystrophy.
• Dry Eye Disease: Weakens the corneal surface.
• Contact Lens Use: Prolonged or improper use.
• Systemic Conditions: Diabetes or a history of ocular herpes.

What are the symptoms of RCE?

Key symptoms include:

• Sharp eye pain, often worse in the morning.
• Blurred vision due to surface irregularities.
• Light sensitivity (photophobia).
• Excess tearing and a gritty feeling in the eye.
• Redness and possible inflammation.

Why is early diagnosis of RCE important?

Diagnosis involves:

• Slit Lamp Exam: To examine the corneal surface.
• Fluorescein Staining: Highlights damaged areas.
• Testing for underlying conditions like dry eye or corneal dystrophies.

What are the effective treatment options for RCE?

Treatment focuses on healing the cornea, managing symptoms, and preventing future episodes:

Conservative Approaches:

• Lubrication: Use artificial tears or ointments to moisten the cornea, especially overnight.
• Hypertonic Saline: Eye drops or ointments to reduce swelling and support healing.
• Antibiotics or Anti-inflammatory Drops: Prevent infections or reduce inflammation.

Medical Procedures:

• Debridement: Removal of loose epithelium to promote healthy regrowth.
• Anterior Stromal Puncture: Creates small corneal punctures to anchor the epithelium.
• Phototherapeutic Keratectomy (PTK): A laser treatment to smooth the corneal surface.

Advanced Interventions:

• Bandage Contact Lens: Protects the cornea during healing.
• Amniotic Membrane Graft: Encourages healing in severe cases.

How can RCE be prevented?

• Avoid eye trauma and use protective eyewear.
• Keep eyes hydrated with lubricants, especially at night.
• Treat underlying conditions like dry eye or corneal dystrophies.

What is the positive outlook for RCE?

With proper treatment, most patients achieve symptom relief and fewer recurrences. Early management is key to preventing complications like scarring or infections. Consult an eye specialist for tailored care.
