本文对外伤性视神经损伤的解剖、病因、诊断及治疗等方面的研究进展综述如下。1视神经及视神经管的解剖视神经全长50mm左右,分为球内段(长约1mm)、眶内段(长约25mm)、管内段(长约5~6mm)和颅内段(10mm左右)。视神经颅内段为视交叉至视神经管近端部分,由脑组织及脑膜保护,不易受 This article on the traumatic optic nerve injury anatomy, etiology, diagnosis and treatment of research progress are summarized below. Anatomy of the optic nerve and optic canal The optic nerve is about 50 mm in total length and is divided into an intracranial segment (about 1 mm in length), an orbital segment (about 25 mm in length), an intraductal segment (about 5 to 6 mm in length) and an intracranial segment (about 10 mm) . The intracranial optic nerve segment for the optic chiasm to the proximal part of the optic canal, protected by brain tissue and meninges, not susceptible
