ICD-10: H10.019

Acute follicular conjunctivitis, classified under ICD-10 code H10.019, is a type of conjunctivitis characterized by the presence of follicular hyperplasia in the conjunctiva. This condition can affect one or both eyes and is often associated with viral infections, particularly adenoviral infections, but can also be caused by other pathogens or irritants. Below is a detailed overview of the clinical presentation, signs, symptoms, and patient characteristics associated with this condition.

Clinical Presentation

Signs and Symptoms

1. Redness of the Eye: Patients typically present with conjunctival injection, which is the redness of the eye due to inflammation of the conjunctiva. This is often diffuse and can be more pronounced in the bulbar conjunctiva.

2. Follicular Formation: The hallmark of acute follicular conjunctivitis is the presence of follicles on the conjunctiva. These are small, round, elevated lesions that can be seen during an eye examination, particularly in the inferior fornix.

3. Discharge: Patients may experience a watery or mucoid discharge. Unlike bacterial conjunctivitis, the discharge is usually less purulent.

4. Itching and Irritation: Patients often report significant itching, burning, or a gritty sensation in the affected eye(s).

5. Photophobia: Sensitivity to light can occur, leading to discomfort in bright environments.

6. Tearing: Increased lacrimation is common, contributing to the watery discharge.

7. Swollen Lymph Nodes: In some cases, preauricular lymphadenopathy may be present, indicating a viral etiology.

Patient Characteristics

• Age: Acute follicular conjunctivitis can occur in individuals of any age, but it is particularly common in children and young adults, especially in settings where viral infections spread easily, such as schools or daycare centers.

• Epidemiology: The condition is often seen in outbreaks, particularly during the fall and winter months when viral infections are more prevalent.

• History of Recent Illness: Patients may have a recent history of upper respiratory infections or exposure to others with conjunctivitis, suggesting a viral cause.

• Allergic History: While not directly related to acute follicular conjunctivitis, a history of allergies may be relevant, as allergic conjunctivitis can present similarly but typically involves more itching and less discharge.

Differential Diagnosis

When evaluating a patient with suspected acute follicular conjunctivitis, it is essential to differentiate it from other types of conjunctivitis, such as:

• Bacterial Conjunctivitis: Characterized by more purulent discharge and less itching.
• Allergic Conjunctivitis: Often presents with intense itching and a history of allergies.
• Chlamydial Conjunctivitis: May present with similar follicular changes but often has a more chronic course and associated systemic symptoms.

Conclusion

Acute follicular conjunctivitis (ICD-10 code H10.019) is primarily characterized by conjunctival redness, follicular formation, and associated symptoms such as itching and discharge. Understanding the clinical presentation and patient characteristics is crucial for accurate diagnosis and management. If a patient presents with these symptoms, a thorough history and examination are necessary to rule out other causes of conjunctivitis and to determine the appropriate treatment, which may include supportive care and, in some cases, antiviral medications if a viral etiology is confirmed.

Acute follicular conjunctivitis, unspecified eye, is classified under the ICD-10 code H10.019. This condition is commonly referred to by several alternative names and related terms that can help in understanding its nature and context. Below is a detailed overview of these terms.

Alternative Names

1. Acute Follicular Conjunctivitis: This is the primary name for the condition, emphasizing the acute nature and the presence of follicles in the conjunctiva.

2. Viral Conjunctivitis: Often associated with viral infections, acute follicular conjunctivitis can be a manifestation of viral conjunctivitis, particularly when caused by adenoviruses.

3. Allergic Conjunctivitis: While not identical, allergic conjunctivitis can present with similar symptoms, including follicular changes, especially in allergic reactions.

4. Pink Eye: A common layman's term for conjunctivitis in general, though it encompasses various types, including bacterial, viral, and allergic conjunctivitis.

5. Follicular Conjunctivitis: This term highlights the follicular response in the conjunctiva, which is a key feature of the condition.

Related Terms

1. Conjunctivitis: A broader term that refers to inflammation of the conjunctiva, which can be caused by infections, allergies, or irritants.

2. Acute Conjunctivitis: This term refers to the sudden onset of conjunctivitis, which can be due to various causes, including viral, bacterial, or allergic factors.

3. Bacterial Conjunctivitis: While H10.019 specifically refers to follicular conjunctivitis, bacterial conjunctivitis is another common type that may be confused with it.

4. Episcleritis: Although distinct, this term is sometimes mentioned in discussions of conjunctival conditions due to overlapping symptoms.

5. Kerato-conjunctivitis: This term refers to inflammation of both the cornea and conjunctiva, which can occur alongside follicular conjunctivitis.

Acute follicular conjunctivitis, classified under ICD-10 code H10.019, is a specific type of conjunctivitis characterized by the presence of follicular hyperplasia in the conjunctiva. This condition can affect either eye but is noted as "unspecified" when the specific eye is not identified. The diagnosis of acute follicular conjunctivitis involves several criteria, which can be categorized into clinical features, patient history, and diagnostic tests.

Clinical Features

1. Symptoms: Patients typically present with:
   - Redness of the eye (conjunctival injection)
   - Itching or burning sensation
   - Increased tearing (epiphora)
   - Discharge, which may be watery or mucoid
   - Photophobia (sensitivity to light)

2. Signs: Upon examination, healthcare providers may observe:
   - Follicles on the conjunctiva, particularly in the inferior fornix
   - Swelling of the conjunctiva (chemosis)
   - Possible eyelid edema
   - Clear or mucoid discharge, distinguishing it from purulent conjunctivitis

Patient History

1. Recent Exposure: A history of exposure to allergens, irritants, or infectious agents is crucial. This may include:
   - Contact with individuals with conjunctivitis
   - Recent upper respiratory infections, which can be associated with viral conjunctivitis
   - Allergic reactions to environmental factors (e.g., pollen, dust)

2. Duration of Symptoms: The acute nature of the symptoms, typically lasting less than four weeks, is a key factor in diagnosis.

3. Medical History: Any previous history of eye conditions or allergies should be noted, as well as any systemic conditions that may predispose the patient to conjunctivitis.

Diagnostic Tests

1. Slit-Lamp Examination: This examination allows for a detailed view of the conjunctiva and can help identify the presence of follicles and other signs of inflammation.

2. Culture and Sensitivity Tests: In cases where bacterial infection is suspected, cultures may be taken to identify the causative organism, although this is less common in viral or allergic conjunctivitis.

3. Allergy Testing: If allergic conjunctivitis is suspected, skin tests or serum IgE tests may be performed to identify specific allergens.

Differential Diagnosis

It is essential to differentiate acute follicular conjunctivitis from other types of conjunctivitis, such as:
- Bacterial conjunctivitis: Typically presents with purulent discharge and may require different management.
- Viral conjunctivitis: Often associated with upper respiratory infections and may have a more watery discharge.
- Allergic conjunctivitis: Characterized by intense itching and a history of allergies.

Conclusion

The diagnosis of acute follicular conjunctivitis (ICD-10 code H10.019) relies on a combination of clinical symptoms, patient history, and examination findings. Accurate diagnosis is crucial for appropriate management and treatment, which may include antihistamines for allergic causes or supportive care for viral infections. If symptoms persist or worsen, further evaluation may be necessary to rule out other underlying conditions.

Acute follicular conjunctivitis, classified under ICD-10 code H10.019, is a type of conjunctivitis characterized by the presence of follicular hyperplasia in the conjunctiva. This condition can be caused by various factors, including viral infections, bacterial infections, or allergic reactions. The treatment approach for this condition typically involves several standard methods aimed at alleviating symptoms and addressing the underlying cause.

Standard Treatment Approaches

1. Symptomatic Relief

• Artificial Tears: Over-the-counter artificial tears can help lubricate the eyes, providing relief from dryness and irritation associated with conjunctivitis. These drops can wash away allergens and irritants, promoting comfort[1].
• Cold Compresses: Applying a cold compress to the affected eye can reduce swelling and soothe discomfort. This method is particularly effective for alleviating symptoms of inflammation and irritation[1].

2. Antihistamines

• If the conjunctivitis is allergic in nature, oral antihistamines or topical antihistamine eye drops may be prescribed. These medications help reduce itching, redness, and swelling by blocking histamine receptors in the body[1][2].

3. Antibiotic Therapy

• In cases where bacterial infection is suspected, topical antibiotics may be prescribed. Common choices include fluoroquinolones or aminoglycosides, which are effective against a broad range of bacterial pathogens[2]. It is essential to confirm the bacterial nature of the conjunctivitis before initiating antibiotic therapy to avoid unnecessary use.

4. Antiviral Medications

• If the conjunctivitis is determined to be viral, particularly in cases linked to adenoviral infections, antiviral medications may be considered, although they are not always necessary. Supportive care is often sufficient, as viral conjunctivitis typically resolves on its own[2][3].

5. Avoidance of Irritants

• Patients are advised to avoid known irritants, such as smoke, dust, and allergens, which can exacerbate symptoms. Maintaining good hygiene, including frequent hand washing and avoiding touching the face, is crucial to prevent the spread of infection[1][3].

6. Follow-Up Care

• Regular follow-up appointments may be necessary to monitor the condition's progress and adjust treatment as needed. If symptoms persist or worsen, further evaluation may be warranted to rule out other underlying conditions[2].

Conclusion

The management of acute follicular conjunctivitis (ICD-10 code H10.019) involves a combination of symptomatic relief, targeted medication, and preventive measures. By addressing both the symptoms and the underlying causes, healthcare providers can effectively treat this condition and improve patient comfort. It is essential for patients to seek medical advice for a proper diagnosis and tailored treatment plan, especially if symptoms do not improve within a few days or if they experience significant discomfort.

Acute follicular conjunctivitis, classified under ICD-10 code H10.019, is a specific type of conjunctivitis characterized by the presence of follicular hyperplasia in the conjunctiva. This condition can affect one or both eyes, but in this case, the code is used when the affected eye is unspecified.

Clinical Description

Definition

Acute follicular conjunctivitis is an inflammatory condition of the conjunctiva, which is the membrane covering the white part of the eyeball and the inner surface of the eyelids. The term "follicular" refers to the formation of small, round, lymphoid follicles in the conjunctiva, which are indicative of a viral or allergic etiology.

Etiology

The condition can be caused by various factors, including:
- Viral Infections: Commonly associated with adenoviruses, which are responsible for many cases of viral conjunctivitis.
- Bacterial Infections: Less common but can occur, particularly in cases where there is a secondary bacterial infection.
- Allergic Reactions: Allergens can trigger an immune response leading to follicular formation.
- Environmental Irritants: Exposure to smoke, dust, or chemicals may also contribute to the development of this condition.

Symptoms

Patients with acute follicular conjunctivitis typically present with:
- Redness of the eye: Due to inflammation of the conjunctiva.
- Itching or burning sensation: Commonly reported by patients.
- Tearing: Increased tear production may occur.
- Discharge: This can vary from watery to mucopurulent, depending on the underlying cause.
- Photophobia: Sensitivity to light may be experienced.

Diagnosis

Diagnosis is primarily clinical, based on the history and physical examination. Key diagnostic steps include:
- Patient History: Assessing symptoms, duration, and potential exposure to infectious agents or allergens.
- Ocular Examination: A thorough examination of the conjunctiva and surrounding structures to identify follicular changes.
- Laboratory Tests: In some cases, conjunctival swabs may be taken to identify specific pathogens, especially if bacterial conjunctivitis is suspected.

Treatment

Management of acute follicular conjunctivitis depends on the underlying cause:
- Viral Conjunctivitis: Typically self-limiting; supportive care includes cool compresses and artificial tears.
- Bacterial Conjunctivitis: Antibiotic eye drops may be prescribed if a bacterial infection is confirmed.
- Allergic Conjunctivitis: Antihistamines or mast cell stabilizers may be used to alleviate symptoms.

Conclusion

ICD-10 code H10.019 is used for acute follicular conjunctivitis when the specific eye affected is not specified. Understanding the clinical features, causes, and management options is crucial for effective diagnosis and treatment. If symptoms persist or worsen, patients should seek further evaluation from an eye care professional to rule out more serious conditions.
