A54.33 Gonococcal keratitis

Name of the Condition

• Gonococcal keratitis

Summary

Gonococcal keratitis is an infection of the cornea caused by Neisseria gonorrhoeae. It is a sexually transmitted infection that may present with or without symptoms and is characterized by localized inflammation. The condition is often associated with exposure to infected genital secretions.

Causes

The infection is caused by Neisseria gonorrhoeae, a bacterium transmitted through contact with infected genital secretions. The bacteria colonize the corneal surfaces, leading to infection. Transmission typically occurs via direct contact with contaminated fluids, such as during sexual activity or from mother to newborn during delivery.

Risk Factors

• Unprotected sexual activity with an infected partner
• Neonatal exposure during vaginal delivery
• History of gonococcal infections
• Lack of consistent condom use
• Presence of other sexually transmitted infections

Symptoms

• Severe eye pain or irritation
• Redness and swelling of the eye
• Sensitivity to light
• Blurred vision
• Purulent discharge
• Corneal opacity or ulceration

Diagnosis

Diagnosis involves clinical evaluation and laboratory testing. Nucleic acid amplification tests (NAATs) on corneal swabs are commonly used to detect Neisseria gonorrhoeae. Gram staining of discharge may show gram-negative diplococci, and culture can confirm the diagnosis.

Treatment Options

Treatment typically involves topical and systemic antibiotics, such as ceftriaxone or cefixime, to target Neisseria gonorrhoeae. Topical antibiotics may be used to address localized infection, while systemic therapy ensures comprehensive coverage. Prompt treatment is essential to prevent complications.

Prognosis and Follow-Up

With early and appropriate treatment, the prognosis is generally good, though corneal scarring or vision impairment may occur if the infection is severe or delayed. Follow-up appointments are necessary to monitor healing and assess for potential complications.

Complications

• Corneal scarring
• Vision loss or impairment
• Chronic eye pain
• Secondary bacterial infections
• Spread of infection to other eye structures

Lifestyle & Prevention

• Practice safe sex with consistent condom use
• Avoid contact with infected genital secretions
• Seek prenatal care to prevent neonatal transmission
• Promptly treat any gonococcal infections
• Maintain good eye hygiene

When to Seek Professional Help

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

Tips for Medical Coders

When coding for gonococcal keratitis, use ICD-10-CM code A54.33. Ensure documentation supports the diagnosis, including clinical findings, laboratory results, and treatment details. Verify that the code aligns with the specific location (cornea) and etiology (gonococcal) to ensure accurate reporting.
