H20.0 Acute and subacute iridocyclitis

Name of the Condition

• Acute and Subacute Iridocyclitis

Summary

Acute and subacute iridocyclitis is an inflammatory condition affecting the iris and ciliary body of the eye. It presents over a period of days (acute) or weeks (subacute) and can cause eye discomfort or vision problems if untreated.

Causes

The exact cause is often unknown. It may be associated with autoimmune disorders, infections, or trauma to the eye. In some cases, it might be idiopathic with no identifiable cause.

Risk Factors

• Autoimmune diseases (e.g., rheumatoid arthritis, ankylosing spondylitis)
• Previous episodes of iridocyclitis
• Eye trauma
• Certain infections (e.g., herpes simplex, tuberculosis)

Symptoms

• Eye redness
• Blurred vision
• Eye pain or discomfort
• Sensitivity to light (photophobia)
• Tearing

Diagnosis

Diagnosis is typically made through a comprehensive eye examination by an ophthalmologist, including a slit-lamp examination to observe inflammation. In some cases, blood tests or imaging may be performed to rule out underlying systemic conditions.

Treatment Options

• Corticosteroid eye drops to reduce inflammation
• Dilating drops to alleviate pain and prevent iris adhesions
• Oral medications for severe cases
• Addressing any underlying systemic condition if identified

Prognosis and Follow-Up

With timely treatment, symptoms usually improve. Regular eye examinations are essential to monitor recurrence or complications.

Complications

• Glaucoma
• Cataracts
• Permanent vision loss if untreated

Lifestyle & Prevention

• Protect the eyes from injury
• Manage autoimmune conditions with medical supervision
• Avoid known triggers, such as certain infections

When to Seek Professional Help

Seek immediate medical attention if experiencing severe eye pain, sudden vision loss, or worsening symptoms.

Tips for Medical Coders

Document the laterality (e.g., right, left, bilateral) and specify if the condition is acute or subacute. Ensure clinical documentation supports the diagnosis and any associated systemic conditions.
