Update on Treatment of Idiopathic (and Non-Idiopathic) Orbital Inflammation

Abstract

Purpose of review

This review aims to provide a critical appraisal of current diagnostic and therapeutic strategies for patients with orbital inflammatory disease (OID). We present the reader with a review of clinical, imaging, laboratory, and biopsy based assessment of OID and review the current treatment modalities utilized including corticosteroids, corticosteroid-sparing (immunomodulatory) agents, radiation, antibiotics, and disease specific therapy.

Recent findings

Two major developments and trends have emerged in the management of orbital inflammation. First, improved understanding and distinction of inflammation subtypes (myositis, dacryoadenitis, or infiltrative) allows for more nuanced workup and treatment. Second, immunomodulatory agents have shown promise in achieving disease control in cases of truly idiopathic or corticosteroid-resistant OID. Together, these advances have led to fewer adverse effects and better efficacy.

Summary

The optimal treatment of OID depends on distinguishing between nonspecific and specific inflammation. Nonspecific inflammation tends to respond to corticosteroid therapy with a lower chance of relapse, while specific orbital inflammation often requires targeting the underlying disease with steroid-sparing therapy and immunomodulatory agents.
