Fig. 18 A. A 27-year-old woman sustained a blow to the left eye from a motor vehicle accident 3 days prior to this examination. Upgaze is limited on the left; the globe is ptotic and enophthalmic. B. Computed tomography scan demonstrates a large orbital floor fracture and a large inferior rectus muscle (arrow) that is not entrapped within the fracture.
