Marginal Corneal Ulcers: Symptoms and Treatment Options

Marginal corneal ulcer

Hello, Doctor Gao: I experience intermittent episodes of eye discomfort on both sides, sometimes affecting all three areas at once.
During the onset, my eyes feel sharp pain and redness, accompanied by a white halo.
After two to three days, the redness gradually subsides and heals.
The increasing frequency and unpredictability of these episodes are quite distressing.
Are there any methods for improvement? Thank you!

Dear Mrs.
Chen,
If your symptoms are indicative of marginal keratitis (ulcer), it is primarily due to an immune allergic reaction to staphylococcal toxins.
When medication is necessary, the main treatments are antibiotics and corticosteroids.
To prevent recurrence, it is essential for patients to maintain long-term cleanliness of the eyelids and contact lenses.
If you are experiencing significant discomfort, you may also use preservative-free artificial tears to alleviate symptoms.
In case of an outbreak, please ensure to seek medical attention to avoid complications such as corneal ulcer perforation.
Puzih Hospital Ophthalmology Department: Monday to Friday from 8:00 AM to 12:00 PM and Wednesday from 1:00 PM to 4:30 PM.
We hope to have the opportunity to serve you.
Sincerely,
Gao Pilin

More Info

Marginal corneal ulcers, also known as marginal keratitis, are localized areas of inflammation and ulceration at the edge of the cornea. They can be quite uncomfortable and may lead to significant visual disturbances if not treated properly. Understanding the symptoms, causes, and treatment options for marginal corneal ulcers is crucial for effective management.

Symptoms
The symptoms of marginal corneal ulcers can vary but typically include:
1. Eye Pain: Patients often experience sharp or stabbing pain in the affected eye, which can be exacerbated by blinking or exposure to light.

2. Redness: The eye may appear red and inflamed, particularly around the limbus (the border between the cornea and the sclera).

3. Discharge: There may be a watery or purulent discharge from the eye.

4. Visual Disturbances: Patients might notice blurred vision or halos around lights, especially during the initial stages of the ulcer.

5. Sensitivity to Light: Photophobia, or sensitivity to light, is common and can make it uncomfortable to be in bright environments.

Causes
Marginal corneal ulcers can be caused by various factors, including:
- Bacterial Infections: Often associated with staphylococcal infections, which can occur due to eyelid margin disease or blepharitis.

- Viral Infections: Herpes simplex virus can also lead to corneal ulcers.

- Allergic Reactions: Allergens can cause inflammation and lead to ulceration.

- Contact Lens Use: Poor hygiene or prolonged wear of contact lenses can increase the risk of developing corneal ulcers.

- Dry Eye Syndrome: Insufficient tear production can lead to corneal damage and ulceration.

Treatment Options
The treatment for marginal corneal ulcers typically involves a combination of medical and supportive therapies:
1. Topical Antibiotics: If a bacterial infection is suspected, antibiotic eye drops are often prescribed to eliminate the infection. Common choices include fluoroquinolones or bacitracin.

2. Anti-inflammatory Medications: Corticosteroid eye drops may be used to reduce inflammation, but they should be prescribed cautiously, as they can exacerbate infections if used improperly.

3. Artificial Tears: For patients with dry eyes, using preservative-free artificial tears can help maintain moisture and promote healing.

4. Warm Compresses: Applying warm compresses to the eyes can help alleviate discomfort and promote drainage if there is any discharge.

5. Avoiding Contact Lenses: Patients are usually advised to refrain from wearing contact lenses until the ulcer has completely healed.

6. Follow-up Care: Regular follow-up with an eye care professional is essential to monitor the healing process and adjust treatment as necessary.

Prevention
To prevent marginal corneal ulcers, consider the following:
- Maintain good eyelid hygiene, especially if you have blepharitis.

- Avoid touching your eyes with unwashed hands.

- Ensure proper contact lens hygiene and follow recommended wear schedules.

- Use artificial tears regularly if you suffer from dry eyes.

Conclusion
If you are experiencing recurrent episodes of marginal corneal ulcers, it is essential to consult with an eye care professional for a comprehensive evaluation. They may recommend additional diagnostic tests to determine the underlying cause of your condition and tailor a treatment plan specific to your needs. Early intervention can help prevent complications and improve your quality of life.
