眼球由眶内脱出,而结膜、眼外肌和视神经仍附着于眶内者,叫做眼球脱臼。这些组织完全离断,眼球游离叫做眼球脱离。二者都是外伤引起的少见疾病,尤其是外伤性眼球脱离更为罕见。近年,由于CT扫描等影像学的进步,又有关于在本病中发生颅内并发症的报告。外伤性眼球脱离的发病机理:①因压迫造成眶腔狭窄,②进入眼球与眶壁间的钝性物体所形成的杠杆 Eye from the orbital prolapse, and the conjunctiva, extraocular muscles and optic nerve is still attached to the orbital, called dislocation of the eye. These organizations completely broken off, the eyeball is called eyeball detachment. Both are rare diseases caused by trauma, especially traumatic eyeball detachment is more rare. In recent years, due to advances in imaging such as CT scanning, there are reports of intracranial complications in this disease. Pathogenesis of traumatic eye detachment: ① compression of the orbital cavity caused by stenosis, ② into the eye and the orbital between the formation of the blunt object lever
