We present a case of optic nerve avulsion as a result of finger-poke injury to the eye. Spectral domain optical coherence tomography demonstrated a plunging cup indicative of the avulsion, a finding not previously described. Optic nerve avulsion is a form of anterior indirect traumatic optic neuropathy evoked by a sudden severe rotation at the junction of the optic nerve and globe induced, in this case, by penetration of the finger into the nasal orbit.
我们报告了一例因手指戳伤眼睛导致的视神经撕脱。频域光相干断层扫描显示了一个深陷的杯状凹陷，提示存在视神经撕脱，这是以前未曾描述过的发现。视神经撕脱是一种前部间接性外伤性视神经病变，由视神经和眼球交界处的突然剧烈旋转引起，在这种情况下，手指穿透鼻眶导致了这种旋转。
