H30.21 Posterior cyclitis, right eye

Name of the Condition

• Posterior Cyclitis, Right Eye

Summary

Posterior cyclitis, right eye, is inflammation of the posterior segment of the ciliary body in the right eye. This structure supports lens function and produces aqueous humor. The condition may affect vision and requires clinical evaluation for management.

Causes

The exact cause of posterior cyclitis may be unknown in some cases. Possible triggers include infections (such as viral or bacterial agents), autoimmune disorders, or systemic inflammatory diseases. In some instances, the cause remains undetermined.

Risk Factors

• Immunocompromised state
• Pre-existing autoimmune conditions
• Previous eye infections or inflammations
• Systemic diseases with inflammatory components

Symptoms

• Blurry vision
• Eye pain or discomfort
• Sensitivity to light (photophobia)
• Eye redness
• Floaters or flashes of light in vision

Diagnosis

Diagnosis typically involves a comprehensive eye examination by an ophthalmologist, including slit-lamp evaluation and fundoscopic inspection of the right eye. Additional tests such as optical coherence tomography (OCT) or blood work may be used to identify underlying causes or systemic involvement.

Treatment Options

• Corticosteroids (oral or topical) to reduce inflammation
• Antimicrobial medications if an infection is identified
• Immunosuppressive agents for autoimmune-related cases

Prognosis and Follow-Up

Prognosis depends on the underlying cause and timeliness of treatment. With appropriate management, many patients experience improvement in symptoms and vision. Follow-up care with an ophthalmologist is essential to monitor for recurrence or complications.

Complications

• Vision loss
• Cataract formation
• Glaucoma
• Retinal damage

Lifestyle & Prevention

• Protect the eyes from injury
• Manage systemic inflammatory conditions
• Avoid known triggers (if identifiable)
• Maintain regular eye examinations

When to Seek Professional Help

Seek immediate medical attention if experiencing sudden vision changes, severe eye pain, or increased sensitivity to light, as these may indicate worsening inflammation or complications.

Tips for Medical Coders

Document the specific eye (right) and laterality in the medical record. Ensure clinical documentation supports the diagnosis of posterior cyclitis and specifies the affected eye to justify code assignment.
