title: Coup de sabre presenting with worsening diplopia and enophthalmos.
abstract: A middle-aged woman with a diagnosis of linear scleroderma and systemic sclerosis presented with an atrophic skin lesion of the forehead extending in the right orbit and progressive diplopia in the right gaze. On exam, she had enophthalmos with a small, manifest esotropia in the right gaze. Orbital MRI revealed fat atrophy of the right upper eyelid and orbit not previously described. Inflammation and progressive collagen fibrosis involving subcutaneous tissue, fat, and muscle secondary to linear scleroderma may result in enophthalmos and diplopia.
