Study Notes
Idiopathic Orbital Inflammatory Disease (IOID)
- Benign, non-infectious, non-neoplastic inflammatory process with no known cause.
- Commonly occurs between the ages of 30 and 50 without gender or racial preferences.
- Represents 16% of all cases of unilateral ptosis in adults.
- Involves any or all orbital soft tissues causing myositis, dacryoadenitis, optic perineuritis, or scleritis.
- Characterized by painful, warm, red, and swollen areas.
- May be associated with systemic vasculitis like Wegener's granulomatosis.
- Third most common orbital disease after Graves' disease and lymphoproliferative disorders (LPDs).
- Diagnosis is often based on clinical findings, imaging, and exclusion of other conditions.
- Treatment often involves corticosteroids, with radiation therapy reserved for cases unresponsive to steroids or recurrences.
Idiopathic Orbital Myositis
- Rare inflammatory disorder of extraocular eye muscles, a subtype of IOID.
- Characterized by chronic inflammatory cellular infiltrate in muscle fibers.
- Presents with acute pain exacerbated by eye movements and diplopia.
- May lead to mild proptosis and permanent restrictive myopathy in chronic cases.
- Diagnosis is confirmed through CT scans showing fusiform enlargement of the muscles.
- Treatment involves NSAIDs for mild cases, systemic steroids for dramatic improvement, and radiotherapy for limiting recurrences.
Tolosa-Hunt Syndrome (THS)
- Diagnosis of exclusion, a rare granulomatous inflammation within the cavernous sinus or superior orbital fissure.
- Presents with acute, constant orbital pain, ophthalmoplegia, and pupillary dysfunction.
- May involve the trigeminal nerve causing forehead paresthesia.
- May manifest with Horner's syndrome due to sympathetic nerve involvement.
- Treatment involves corticosteroids, usually providing pain relief within 24-72 hours.
Granulomatosis with Polyangiitis (Wegener Granulomatosis)
- Rare multisystem autoimmune disease with unknown etiology.
- Characterized by necrotizing granulomatous inflammation and pauci-immune vasculitis in small and medium-sized blood vessels.
- Most commonly affects the paranasal sinuses followed by pulmonary and renal disease.
- Diagnosed through the c-ANCA test.
- May present with chronic sinusitis, rhinitis, epistaxis, saddle nose deformity, serous otitis media, and hearing loss.
- Ocular signs include proptosis, eyelid edema, ophthalmoplegia, scleritis, conjunctivitis, uveitis, and episcleritis.
- Systemic signs include fevers, night sweats, fatigue, and lethargy.
