H15.03 Posterior scleritis

Name of the Condition

• Posterior Scleritis
• Medical Term: Posterior Scleritis
• ICD Code: H15.03

Summary

Posterior scleritis is an inflammatory condition affecting the posterior (rear) portion of the sclera, the tough, white outer layer of the eyeball. It can cause significant eye pain and may lead to vision-threatening complications if not managed appropriately. The condition often requires prompt evaluation and treatment to prevent long-term damage.

Causes

Posterior scleritis may result from autoimmune disorders, infections, or systemic inflammatory diseases. Autoimmune conditions such as rheumatoid arthritis, lupus, or granulomatosis with polyangiitis are common underlying causes. Infections like herpes zoster or syphilis, as well as trauma or surgery, can also trigger scleral inflammation. In some cases, the cause remains idiopathic.

Risk Factors

• Autoimmune diseases (e.g., rheumatoid arthritis, lupus)
• Systemic inflammatory conditions (e.g., vasculitis)
• History of eye trauma or surgery
• Age-related changes in scleral tissue
• Exposure to infectious agents

Symptoms

• Severe, deep eye pain, often described as aching or throbbing
• Redness, typically localized to the sclera
• Blurred vision or reduced visual acuity
• Sensitivity to light (photophobia)
• Tearing or discharge
• Possible swelling of the eyelids

Diagnosis

Diagnosis involves a comprehensive eye examination by an ophthalmologist, including slit-lamp evaluation and imaging studies such as ultrasound or MRI to assess the posterior sclera. Laboratory tests may be performed to identify underlying systemic conditions.

Treatment Options

Treatment typically includes anti-inflammatory medications, such as corticosteroids or immunosuppressants, to reduce inflammation. Topical or systemic therapies may be used depending on the severity. Underlying causes, such as autoimmune disorders, are addressed to prevent recurrence.

Prognosis and Follow-Up

With appropriate treatment, most patients experience improvement in symptoms and preservation of vision. Regular follow-up is essential to monitor for complications and adjust therapy as needed. Long-term management may be required for chronic or recurrent cases.

Complications

• Vision loss or permanent visual impairment
• Retinal detachment
• Glaucoma
• Cataracts
• Optic nerve damage

Lifestyle & Prevention

• Manage underlying autoimmune or inflammatory conditions
• Protect the eyes from trauma or injury
• Avoid known triggers, such as infections or allergens
• Maintain regular eye examinations

When to Seek Professional Help

Seek immediate medical attention if you experience sudden vision changes, severe eye pain, or persistent redness. Early intervention is critical to prevent irreversible damage.

Tips for Medical Coders

Document the location (posterior) and any associated systemic conditions or triggers. Ensure clinical notes support the diagnosis and specify whether the condition is acute or chronic. Include details of imaging or laboratory findings to confirm the diagnosis.
