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.
