ICD-10: H16.421

Pannus, specifically in the context of the ICD-10-CM code H16.421, refers to a condition affecting the cornea of the right eye. This condition is characterized by the growth of vascularized granulation tissue over the cornea, which can lead to visual impairment and other complications. Below is a detailed clinical description and relevant information regarding this diagnosis.

Clinical Description of Pannus (Corneal)

Definition

Pannus is defined as a pathological condition where there is an abnormal growth of tissue, typically involving the cornea. This growth can be due to various underlying causes, including chronic inflammation, trauma, or certain systemic diseases. The presence of pannus can obstruct vision and may lead to further ocular complications if not addressed.

Symptoms

Patients with corneal pannus may experience a range of symptoms, including:
- Visual Disturbances: Blurred vision or decreased visual acuity due to the obstruction of light entering the eye.
- Discomfort: Patients may report a sensation of foreign body presence or irritation in the eye.
- Redness and Inflammation: The affected area may appear red and inflamed, indicating underlying irritation or infection.
- Tearing: Increased tear production may occur as a response to irritation.

Causes

The development of corneal pannus can be attributed to several factors, including:
- Chronic Inflammatory Conditions: Conditions such as keratitis or conjunctivitis can lead to the formation of pannus.
- Trauma: Previous injuries to the eye can result in abnormal healing and tissue growth.
- Systemic Diseases: Conditions like rheumatoid arthritis or other autoimmune disorders may predispose individuals to develop pannus.

Diagnosis

Diagnosis of corneal pannus typically involves:
- Clinical Examination: An ophthalmologist will perform a thorough eye examination, often using slit-lamp biomicroscopy to visualize the cornea and assess the extent of the pannus.
