In the radiographical evaluation of the orbital apex syndrome, standard radiographs, tomograms, and computed tomographic scans have proved useful in the demonstration of the bony pathology, especially for optic canal fractures. The limitation of these methods, however, remains in their inability to provide accurate delineation of the associated soft tissue pathology, including the presence of optic nerve sheath hematoma. Recent developments in computer technology and graphic imaging are now available to provide an accurate three-dimensional radiographical analysis of the extent of skeletal and soft tissue injury in the orbital apex syndrome. The physician, in essence, can perform a radiographical "living autopsy". The technique was used to evaluate a patient with bilateral apex syndrome. It clearly showed that a severe direct injury to the intracanalicular portion of the optic nerve was responsible for the development of blindness in this patient. The progression of optic nerve injury, from perineural sheath hematoma to the ultimate development of optic nerve atrophy and fibrosis, was radiographically documented.
在眶尖综合征的影像学评估中，标准X线片、体层摄影和计算机断层扫描已被证明有助于显示骨病变，尤其是对视神经管骨折。然而，这些方法的局限性在于无法准确描绘相关的软组织病变，包括视神经鞘血肿的存在。计算机技术和图形成像的最新进展现在可用于对眶尖综合征中骨骼和软组织损伤的范围进行准确的三维影像学分析。从本质上讲，医生可以进行影像学的“活体解剖”。该技术用于评估一名双侧眶尖综合征患者。它清楚地表明，视神经管内段的严重直接损伤是该患者失明的原因。通过影像学记录了视神经损伤从神经鞘血肿到最终视神经萎缩和纤维化的发展过程。
