ICD-10: H16.253

Phlyctenular keratoconjunctivitis is a specific type of ocular inflammation characterized by the presence of a phlyctenule, which is a small, elevated, and often vascularized lesion that typically appears on the conjunctiva or cornea. This condition is primarily associated with hypersensitivity reactions, often due to infections, particularly those caused by Mycobacterium tuberculosis or Chlamydia species, but can also be triggered by other factors such as bacterial infections or environmental allergens.

Clinical Description of H16.253: Phlyctenular Keratoconjunctivitis, Bilateral

Definition

ICD-10 code H16.253 refers specifically to bilateral phlyctenular keratoconjunctivitis, indicating that the condition affects both eyes. This bilateral involvement can lead to more pronounced symptoms and complications compared to unilateral cases.

Symptoms

Patients with bilateral phlyctenular keratoconjunctivitis may experience a range of symptoms, including:
- Redness and irritation: Both eyes may appear red and inflamed due to conjunctival involvement.
- Photophobia: Increased sensitivity to light is common, as the inflammation can affect the cornea.
- Tearing: Excessive tearing may occur as a response to irritation.
- Discomfort or pain: Patients often report a sensation of grittiness or pain in the eyes.
- Visual disturbances: In some cases, vision may be affected, particularly if the cornea is involved.

Etiology

The etiology of phlyctenular keratoconjunctivitis is often linked to:
- Infectious agents: The most common cause is a hypersensitivity reaction to Mycobacterium tuberculosis, but other bacteria and viruses can also be implicated.
- Allergic reactions: Environmental allergens may trigger similar inflammatory responses.
- Chronic irritation: Prolonged exposure to irritants can lead to the development of phlyctenules.

Diagnosis

Diagnosis typically involves:
- Clinical examination: An ophthalmologist will perform a thorough examination of the eyes, looking for characteristic lesions.
- History taking: A detailed patient history, including any previous infections or exposure to allergens, is crucial.
- Additional tests: In some cases, further testing may be required to identify underlying infections or allergies.

Treatment

Management of bilateral phlyctenular keratoconjunctivitis may include:
- Topical corticosteroids: To reduce inflammation and alleviate symptoms.
- Antibiotics: If a bacterial infection is suspected or confirmed.
- Antihistamines: For allergic reactions, oral or topical antihistamines may be prescribed.
- Avoidance of irritants: Identifying and avoiding potential triggers is essential for long-term management.

Prognosis

The prognosis for patients with phlyctenular keratoconjunctivitis is generally good, especially with appropriate treatment. However, if left untreated, complications such as corneal scarring or vision loss can occur, particularly in cases where the cornea is significantly involved.

In summary, ICD-10 code H16.253 denotes bilateral phlyctenular keratoconjunctivitis, a condition that requires careful diagnosis and management to prevent complications and ensure optimal patient outcomes. Regular follow-up with an ophthalmologist is recommended to monitor the condition and adjust treatment as necessary.

Phlyctenular keratoconjunctivitis (PKC) is a specific type of keratoconjunctivitis characterized by the presence of a phlyctenule, which is a small, elevated, and often vascularized lesion on the conjunctiva or cornea. The ICD-10 code H16.253 specifically refers to bilateral phlyctenular keratoconjunctivitis. Below is a detailed overview of its clinical presentation, signs, symptoms, and patient characteristics.

Clinical Presentation

Definition and Etiology

Phlyctenular keratoconjunctivitis is primarily an immune-mediated response to antigens, often associated with infections such as tuberculosis or chlamydia, or other irritants. The bilateral nature of H16.253 indicates that both eyes are affected, which can lead to more pronounced symptoms and signs.

Patient Characteristics

• Age: PKC can occur in individuals of any age but is more commonly seen in children and young adults.
• Gender: There is no significant gender predisposition, although some studies suggest a slight male predominance.
• Geographic and Socioeconomic Factors: Higher prevalence is noted in areas with endemic infections, particularly tuberculosis, and in populations with limited access to healthcare.

Signs and Symptoms

Common Symptoms

1. Redness: Patients often report conjunctival hyperemia, leading to a red appearance of the eyes.
2. Discomfort or Pain: Mild to moderate discomfort or a sensation of foreign body presence is common.
3. Photophobia: Increased sensitivity to light may occur due to inflammation.
4. Tearing: Excessive tearing or watery eyes can be a symptom.
5. Visual Disturbances: Blurred vision may occur if the cornea is involved.

Clinical Signs

1. Phlyctenule Formation: The hallmark sign is the presence of a phlyctenule, which appears as a small, elevated, and often pinkish-white lesion on the conjunctiva or cornea. In bilateral cases, these lesions may be present in both eyes.
2. Conjunctival Injection: There is typically significant conjunctival injection surrounding the phlyctenule.
3. Corneal Involvement: If the cornea is affected, there may be associated keratitis, which can lead to corneal opacities or scarring.
4. Lymphadenopathy: In cases associated with systemic infections, such as tuberculosis, preauricular lymphadenopathy may be observed.

Diagnosis and Management

Diagnosis is primarily clinical, based on the characteristic signs and symptoms. A thorough history, including potential exposure to infectious agents and a review of systemic health, is essential. Management typically involves addressing the underlying cause, which may include topical corticosteroids to reduce inflammation and antibiotics if a bacterial infection is suspected.

Conclusion

Phlyctenular keratoconjunctivitis, particularly in its bilateral form (ICD-10 code H16.253), presents with distinctive clinical features that include redness, discomfort, and the presence of phlyctenules. Understanding the patient characteristics and clinical signs is crucial for timely diagnosis and effective management. If you suspect PKC, it is advisable to consult an eye care professional for a comprehensive evaluation and treatment plan.
