Orbital compartment syndrome as the first manifestation of SLE.

The occurrence of orbital compartment syndrome is a rare and unusual complication of systemic lupus erythematosus (SLE). Patients will present with symptoms of ocular pain and diplopia and visible signs of proptosis. The condition is considered an ophthalmological emergency because the myositis involving the ocular muscles can cause irrevocable damage to the retina and optic disk, potentially leading to blindness. We report a case of a young African American male who developed orbital myositis with compartment syndrome as his initial manifestation of SLE. The patient underwent an emergent orbital decompression, followed by prompt initiation of immunosuppressant medications. To our knowledge, this is the first report of a case of myositis secondary to SLE complicated by compartment syndrome of the orbit.
