The optic nerve can be injured indirectly by blunt trauma to the frontoorbital region. The mechanism of injury is related to trauma of the nerve in the tight, bony optic canal. Neurovisual transmission in the canal is interrupted by pressure on the nerve. The conventional management includes careful observation and supportive treatment. Recent interest in this unique clinical problem has prompted the development of new techniques to decompress the injured optic canal extracranially; these approaches have produced encouraging results. Another dividend of the method has been the mapping of the optic nerve region under magnification using the operating room microscope. Any gain of vision, partial or complete, is well appreciated by the patient and the physician.
视神经可因额眶区域的钝性创伤而间接受损。损伤机制与紧密的骨性视神经管内神经的创伤有关。神经管内的神经视觉传导因神经受压而中断。传统的治疗方法包括仔细观察和支持性治疗。最近对这一独特临床问题的关注促使人们开发了新的技术，用于在颅外对视神经管进行减压；这些方法已取得了令人鼓舞的结果。该方法的另一个好处是，利用手术显微镜在放大条件下对视神经区域进行了测绘。患者和医生都非常珍视视力的任何改善，无论是部分改善还是完全恢复。
