H10.223 Pseudomembranous conjunctivitis, bilateral

Name of the Condition

• Pseudomembranous conjunctivitis, bilateral

Summary

Pseudomembranous conjunctivitis, bilateral, is a severe form of conjunctival inflammation affecting both eyes, characterized by the formation of a pseudomembrane—a layer of inflammatory exudate adhering to the conjunctiva. It typically presents with marked redness, irritation, and discharge, and requires prompt clinical attention due to associated discomfort and potential complications.

Causes

Pseudomembranous conjunctivitis can result from various infectious or inflammatory processes. Common causes include bacterial infections (e.g., Corynebacterium diphtheriae, Streptococcus pneumoniae), viral infections (e.g., adenovirus), or severe allergic reactions. The pseudomembrane forms due to the accumulation of fibrin, inflammatory cells, and debris on the conjunctival surface.

Risk Factors

• Severe bacterial or viral infections of the eye.
• Untreated or poorly managed conjunctivitis.
• Immunocompromised states, which may increase susceptibility to severe infections.
• Exposure to highly virulent pathogens or allergens.
• Delayed or inadequate treatment of underlying conditions.

Symptoms

• Intense redness and swelling of the conjunctiva in both eyes.
• Thick, purulent or mucopurulent discharge.
• Formation of a pseudomembrane on the conjunctiva, which may be adherent or easily removable.

Diagnosis

Diagnosis is based on clinical examination, including assessment of the conjunctiva for pseudomembrane formation, redness, and discharge. Laboratory tests (e.g., cultures, PCR) may be used to identify the underlying cause, such as bacterial or viral pathogens. slit lamp examination helps evaluate the extent of inflammation and membrane adherence.

Treatment Options

Treatment targets the underlying cause and symptoms. Antibiotics or antivirals may be prescribed for infectious etiologies, while corticosteroids or antihistamines address inflammation or allergic reactions. Warm compresses and lubricating eye drops can alleviate discomfort. Severe cases may require membrane removal under medical supervision.

Prognosis and Follow-Up

With appropriate treatment, most cases resolve without long-term complications. Follow-up is recommended to monitor for recurrence or progression, especially if the underlying cause is not fully addressed. Immunocompromised patients or those with severe infections may require extended care.

Complications

Potential complications include corneal involvement (e.g., keratitis), vision impairment, or chronic conjunctivitis. Delayed treatment may increase the risk of scarring or permanent tissue damage.

Lifestyle & Prevention

• Practice good hand hygiene to reduce infection risk.
• Avoid sharing personal items (e.g., towels, makeup) to prevent pathogen spread.
• Use protective eyewear in environments with allergens or irritants.
• Seek prompt care for eye infections to prevent progression.

When to Seek Professional Help

Consult a healthcare provider if symptoms worsen, persist beyond a few days, or include severe pain, vision changes, or light sensitivity. Immediate care is needed for membrane formation or suspected infection.

Tips for Medical Coders

Document the bilateral nature of the condition clearly in the medical record. Ensure the pseudomembrane and associated symptoms (e.g., discharge, redness) are described to support the diagnosis. Code H10.223 is specific to bilateral involvement; verify laterality and exclude unilateral codes when appropriate.
