A 29-year-old man presented with a sudden loss of vision after a closed-globe injury. At presentation, he had no light perception in the right eye and the right pupil was dilated and nonreactive to light. On ophthalmological examination, the area of the optic nerve head was excavated, suggesting optic nerve avulsion. Magnetic resonance imaging scan showed optic nerve avulsion without rupture of the optic nerve sheath. Four months after the injury, the patient's visual acuity remained unchanged. Gliosis developed at the avulsion site. Closed-globe injuries may cause severe posterior injury even if there is no anterior damage in the eye. To prevent unnecessary treatment, trauma patients should be examined carefully appropriate imaging to confirm the diagnosis.
一位 29 岁男性在闭合性眼球损伤后出现视力突然丧失。就诊时，右眼无光感，右眼瞳孔散大，对光无反应。眼科检查发现视神经乳头凹陷，提示视神经撕脱。磁共振成像扫描显示视神经撕脱，视神经鞘未破裂。损伤后 4 个月，患者视力仍未改变。撕脱部位发生胶质增生。即使眼球前部没有损伤，闭合性眼球损伤也可能导致严重的后部损伤。为避免不必要的治疗，外伤患者应仔细检查，行适当的影像学检查以明确诊断。
