Two cases of traumatic optic neuropathy presented with profound loss of vision. Both cases received a course of intravenous corticosteroids elsewhere but did not improve. They underwent Navigation guided optic canal decompression via external transcaruncular approach, following which both cases showed visual improvement. Postoperative Visual Evoked Potential and optical coherence technology of Retinal nerve fibre layer showed improvement. These case reports emphasize on the role of stereotactic navigation technology for optic canal decompression in cases of traumatic optic neuropathy.
两例外伤性视神经病变患者表现为严重视力丧失。这两例患者均在其他地方接受了一个疗程的静脉内皮质类固醇治疗，但没有改善。他们通过经外眦入路导航引导的视神经管减压术治疗，术后视力均有改善。术后视觉诱发电位和视网膜神经纤维层光学相干技术显示有所改善。这些病例报告强调了立体定向导航技术在外伤性视神经病变患者视神经管减压中的作用。
