H16.01 Central corneal ulcer

Name of the Condition

• Central corneal ulcer

Summary

Central corneal ulcer is an open sore located at the center of the cornea, the clear front surface of the eye. This condition can cause pain, redness, vision disturbances, and potential scarring if left untreated. It may result from infections, injuries, or underlying eye diseases.

Causes

Central corneal ulcers often develop due to bacterial, viral, or fungal infections. Bacterial causes include organisms like Staphylococcus or Pseudomonas, while viral causes may involve herpes simplex. Fungal ulcers can follow trauma with organic material. Non-infectious causes include dry eye, severe allergies, or chemical injuries.

Risk Factors

• Wearing contact lenses improperly or extended use.
• History of eye injuries or surgeries.
• Use of steroid eye drops.
• Underlying conditions like dry eye syndrome or immune deficiencies.
• Exposure to contaminated water or foreign objects in the eye.

Symptoms

• Severe eye pain and redness.
• Watery or purulent discharge.
• Blurred vision or vision loss.
• Sensitivity to light (photophobia).
• Feeling of a foreign body in the eye.

Diagnosis

Diagnosis involves a comprehensive eye exam, including slit-lamp microscopy to assess the cornea. Cultures or scrapings may be taken to identify infectious agents. Additional tests, such as fluorescein staining, can help visualize the ulcer and assess its severity.

Treatment Options

Treatment depends on the cause and severity. Antibiotic, antiviral, or antifungal eye drops may be prescribed for infections. Pain relief and anti-inflammatory medications can manage symptoms. Severe cases may require surgical intervention.

Prognosis and Follow-Up

With prompt treatment, most central corneal ulcers heal without significant scarring. Follow-up appointments are necessary to monitor healing and adjust treatment. Delayed care can lead to vision loss or permanent damage.

Complications

Potential complications include corneal scarring, vision impairment, perforation of the cornea, and secondary infections. In severe cases, corneal transplantation may be required.

Lifestyle & Prevention

• Practice good hygiene when handling contact lenses.
• Avoid sharing eye makeup or towels.
• Use protective eyewear during activities with risk of eye injury.
• Manage underlying conditions like dry eye or allergies.
• Seek prompt care for eye injuries or infections.

When to Seek Professional Help

Seek immediate medical attention if you experience severe eye pain, sudden vision changes, increased redness, or discharge. Early intervention is critical to prevent complications.

Tips for Medical Coders

Document the specific location (central) and any associated factors, such as infection type or trauma, to support accurate coding. Ensure clinical documentation aligns with the diagnosis and treatment provided.
