H15.053 Scleromalacia perforans, bilateral

Name of the Condition

• Scleromalacia perforans, bilateral
• Medical Term: Scleromalacia perforans
• ICD Code: H15.053

Summary

Scleromalacia perforans is a rare, necrotizing condition of the sclera, the tough outer layer of the eyeball, characterized by thinning and potential perforation. It often occurs in the setting of long-standing rheumatoid arthritis and may lead to serious ocular complications if not addressed. The condition requires careful evaluation to assess structural integrity and underlying systemic associations.

Causes

Scleromalacia perforans is most commonly associated with severe, long-standing rheumatoid arthritis, particularly in patients with seropositive disease. Other systemic inflammatory or autoimmune conditions may rarely contribute. The exact pathophysiology involves scleral necrosis, likely driven by immune complex deposition or vasculitis affecting the scleral vasculature.

Risk Factors

• Long-standing rheumatoid arthritis (especially seropositive)
• Chronic systemic inflammation
• Advanced age
• Female gender (more prevalent in women)

Symptoms

• Painless scleral thinning or visible scleral translucency
• Possible visible uveal tissue (e.g., choroid) through thinned sclera
• Asymptomatic in early stages; may progress to perforation
• Rarely, associated with ocular pain or redness if inflammation is present

Diagnosis

Diagnosis is based on clinical examination, including slit-lamp biomicroscopy to assess scleral thinning or perforation. Imaging studies, such as ultrasound or computed tomography, may be used to evaluate structural integrity. Laboratory tests for rheumatoid arthritis or other systemic conditions may be performed to identify underlying causes.

Treatment Options

Treatment focuses on managing underlying systemic disease, such as rheumatoid arthritis, with immunosuppressive therapy. Surgical intervention may be necessary to repair perforations or reinforce the sclera. Regular monitoring is essential to prevent progression.

Prognosis and Follow-Up

Prognosis depends on the extent of scleral damage and response to treatment. Early intervention improves outcomes, but severe cases may lead to vision loss or ocular perforation. Follow-up includes regular ophthalmologic evaluations to monitor for complications.

Complications

• Ocular perforation
• Vision loss
• Secondary infections
• Progression of underlying systemic disease

Lifestyle & Prevention

• Manage underlying rheumatoid arthritis or other autoimmune conditions with prescribed medications.
• Avoid trauma to the eyes.
• Regular eye examinations for early detection.

When to Seek Professional Help

Seek immediate medical attention if you experience sudden vision changes, eye pain, or visible changes in the eye’s appearance.

Tips for Medical Coders

Document the bilateral nature of the condition and any associated systemic disease (e.g., rheumatoid arthritis) to support code assignment. Ensure clinical documentation specifies the presence of scleral thinning or perforation and confirms bilateral involvement.
