ICD-10: H20.03

Clinical Description of ICD-10 Code H20.03: Secondary Infectious Iridocyclitis

ICD-10 Code H20.03 refers specifically to secondary infectious iridocyclitis, a condition characterized by inflammation of the iris and ciliary body (collectively known as the uvea) that occurs as a result of an infectious process. This condition is classified under the broader category of iridocyclitis, which encompasses various forms of uveitis.

Understanding Iridocyclitis

Iridocyclitis is a type of uveitis that can be classified into two main categories: acute and chronic. The acute form typically presents with sudden onset symptoms, while chronic iridocyclitis may develop gradually and persist over time. The secondary form, as indicated by the H20.03 code, arises due to an underlying infectious agent, distinguishing it from primary iridocyclitis, which may occur without an identifiable infectious cause.

Causes of Secondary Infectious Iridocyclitis

Secondary infectious iridocyclitis can be triggered by various infectious agents, including:

• Bacterial Infections: Such as those caused by Mycobacterium tuberculosis or Chlamydia.
• Viral Infections: Including herpes simplex virus (HSV) and cytomegalovirus (CMV).
• Fungal Infections: Such as those caused by Candida species.
• Parasitic Infections: Including toxoplasmosis, which is a common cause of posterior uveitis that can lead to iridocyclitis.

The infectious nature of this condition necessitates prompt diagnosis and treatment to prevent complications, such as vision loss or glaucoma.

Clinical Presentation

Patients with secondary infectious iridocyclitis may exhibit a range of symptoms, including:

• Eye Pain: Often described as a deep, aching pain.
• Photophobia: Increased sensitivity to light.
• Redness of the Eye: Due to inflammation.
• Blurred Vision: Resulting from swelling and inflammation.
• Tearing: Increased production of tears may occur.

Upon examination, clinicians may observe signs such as keratic precipitates (small deposits on the corneal endothelium), anterior chamber inflammation, and possibly posterior synechiae (adhesions between the iris and lens).

Diagnosis and Management

Diagnosis typically involves a comprehensive eye examination, including slit-lamp examination, and may require additional tests to identify the underlying infectious agent. Laboratory tests, imaging studies, and possibly referral to an infectious disease specialist may be necessary.

Management of secondary infectious iridocyclitis focuses on treating the underlying infection, which may involve:

• Antibiotics: For bacterial infections.
• Antivirals: For viral infections.
• Antifungals: For fungal infections.
• Corticosteroids: To reduce inflammation and manage symptoms.
