Medial orbital wall blow-out fracture producing an acquired retraction syndrome.
Trauma in an 8-year-old Black-Vietnamese boy caused a medial wall blow-out fracture, which presented as an acquired retraction syndrome. Computed tomography demonstrated both the fracture and entrapment of the medial rectus and surrounding tissues. Surgical relief of the entrapment resulted in improvement of ocular motility, but retraction persisted. This is the sixth young black male reported with a medial wall blow-out fracture, which suggests that this group may have an orbital structure vulnerable to this relatively uncommon fracture.
