H20.033 Secondary infectious iridocyclitis, bilateral

Name of the Condition

• Secondary Infectious Iridocyclitis, Bilateral

Summary

Secondary infectious iridocyclitis is an inflammatory condition affecting the iris and ciliary body of both eyes, specifically due to an infectious cause. It is a subtype of anterior uveitis and involves inflammation secondary to an infection elsewhere in the body or eye.

Causes

This condition can be caused by bacterial, viral, fungal, or parasitic infections. Common infectious agents include herpes simplex, cytomegalovirus, and toxoplasmosis. The infection may originate in the eye or spread from systemic infections.

Risk Factors

• Previous eye infections or surgeries
• Immunosuppression, as seen in conditions like HIV/AIDS or use of immunosuppressive medications
• Systemic infections that can affect the eyes

Symptoms

• Redness and pain in both eyes
• Blurred vision
• Sensitivity to light (photophobia)
• Decreased vision in severe cases

Diagnosis

Diagnosis is typically made through a comprehensive eye examination by an ophthalmologist, including a slit-lamp examination to observe inflammation. Laboratory tests may be conducted to identify specific infectious agents, and imaging tests (e.g., ultrasound biomicroscopy) may be used if needed for further examination.

Treatment Options

• Antimicrobial medications specific to the infectious agent (e.g., antivirals for herpes, antibiotics for bacterial infections)
• Corticosteroids to reduce inflammation
• Cycloplegic drops to reduce pain and prevent adhesions

Prognosis and Follow-Up

Prognosis depends on the underlying cause and timeliness of treatment. Early intervention often leads to better outcomes, but recurrent or severe infections may result in complications like vision loss. Regular follow-up with an ophthalmologist is necessary to monitor for recurrence or progression.

Complications

• Vision loss
• Cataracts
• Glaucoma
• Retinal damage

Lifestyle & Prevention

• Maintain good hygiene to reduce infection risk
• Manage systemic conditions that may predispose to infections
• Avoid exposure to known infectious agents when possible

When to Seek Professional Help

Seek immediate medical attention if you experience sudden eye pain, redness, or vision changes, as these may indicate a serious infection requiring prompt treatment.

Tips for Medical Coders

Document the bilateral nature of the condition and confirm the infectious etiology. Ensure clinical documentation supports the diagnosis and specifies involvement of both eyes to justify the code H20.033.
