What is recurrent corneal erosion?

Recurrent corneal erosion (RCE) affects the outer surface layer of the cornea (corneal epithelium). The corneal epithelium protects the cornea from foreign objects (things that shouldn’t be there). In RCE, this outer layer is weak and loose due to poor adhesion to the rest of the cornea. The loose epithelium ‘rips open’ at the points of weakness, especially when waking up, resulting in severe pain.

 

Symptoms

People with RCE usually experience pain after waking up, which can range from mild to severe. Other symptoms include:

  • Redness
  • Watery eyes
  • Blurred vision
  • Irritated, dry eyes
  • Pain – moderate to severe
  • Photophobia (light sensitivity)
  • Feeling as if something is scratching your eye

Your symptoms may lessen throughout the day and recur the next morning. 

 

When should I visit emergency care?

If you experience pain that continues to increase, you may require immediate attention. Other signs include progressive vision loss and pus-like discharge. If you think something is in your eye (a foreign object) and cannot flush it out, speak to a medical professional. Foreign objects in the eye can lead to corneal abrasions and infections.

Causes

The most common cause is a previous injury (trauma) to the eye that hasn’t healed completely. This leaves your epithelial cells unsettled so they can dislodge easily and stick to your eyelids. The corneal epithelium is more likely to stick while you’re sleeping. This is why the pain is often worse after you have woken up and opened your eyes for the first time.

As the epithelium fails to heal, the erosion of your cornea can continue. A change in the cornea caused by an eye condition can also result in epithelial weakening, such as a corneal dystrophy. Common types of dystrophy that can cause RCE include map-dot fingerprint, Reis-Buckler, and lattice dystrophy.

Complications

Long-term complications are rare. You may experience an infection, infectious keratitis, or corneal scarring, which can lead to poor vision.

Risk factors

You are more likely to experience RCE if you’ve had an eye injury or wear your contacts incorrectly. Other risk factors include diabetes, dry eye syndrome, ocular rosacea, and meibomian gland dysfunction. Women and people over 40 are also more likely to experience RCE.

Certain surgeries for eye conditions can also increase the risk, including:

To prevent it, you should avoid dusty, dry environments that could irritate your eyes. We recommend that you avoid rubbing your eyes as well.

Diagnosis

When you visit our clinic, we will discuss your symptoms, including how long you’ve had them and how severe they are. You should tell our ophthalmologist (eye specialist) if your symptoms are worse at any time of day. Asking questions, such as if you have previously hurt your eye, will help us make a diagnosis.

We can also perform a slit lamp examination to diagnose RCE. A slit lamp exam involves using a microscope with a light source to look for corneal injuries, such as abrasion. We may use a yellow dye (fluorescein) in an eye drop to highlight specific areas of the eye. If you have a severe case, we may also use corneal topography to map the surface of your cornea.

Many eye conditions may have similar symptoms. Other possible causes include corneal ulcers, dry eye syndrome, herpes simplex virus (HSV), and exposure keratopathy.

Treatment

Treatment is usually non-invasive, but your treatment plan may evolve to a more invasive approach if your condition is persistent. Our specialists will discuss your circumstances with you.

The initial treatment for RCE involves using a long-term lubricant ointment each night and lubricant eye drops during the day as required. We can combine this with epithelial debridement (removing your loose epithelium) and contact lens fitting to allow better epithelial healing. You may also need an antibiotic eye drop to avoid infection.

To remove damaged corneal epithelium and allow new tissue to grow, we may perform alcohol delamination or phototherapeutic keratectomy (PTK). At Oculase, we prefer PTK if medical therapy fails as it is a definitive treatment. During laser PTK treatment, we can correct your refractive errors, such as myopia (short-sightedness) and astigmatism.

Other surgical options include anterior stromal micropuncture and diamond burr polishing. However, these aren’t commonly used as other interventions, described above, provide better results.

Additionally, we must manage any other eye conditions, such as blepharitis. If you experience dry eyes, we might perform punctual occlusion. Punctual occlusion can slow your tears and any artificial lubrication from draining.

FAQs

    It depends on the cause. If a corneal trauma caused your RCE, then it will likely affect one eye only. However, if you have corneal weakening from a change within the cornea, both eyes can be affected.

    It can resolve on its own. Most cases require treatment of some kind and RCE will often recur without medical intervention.

    With the appropriate treatment, the prognosis is generally excellent. However, a small number of people experience frequent painful episodes of RCE, especially if their condition is poorly managed.

    Using a lubricating ointment at night could help prevent RCE. You should treat any underlying eye condition. We also recommend wearing protective gear when exposed to anything that could injure your eye. Your eye specialist can discuss the best way to open your eyes in the morning to prevent friction resulting in corneal erosion.

    They often heal within a few days to a week. However, people with RCE may experience multiple episodes over the years. You will need to manage your condition carefully to prevent this.

    The pain differs for different people. Some people experience mild pain, while others have severe, sharp pain. The pain should gradually subside as your eye heals. If you experience stabbing pain for more than 24 hours, speak to our expert eye specialist.
