Using a fiber-dissection technique, our aim is to study the fiber bundles of the optic radiation. We focused on the course, the length, anatomical relations with lateral ventricle and the relevance of these finding during surgery in the region.
Five previously frozen and formalin-fixed cadaveric human brains were used. The dissection was done using the operating microscope. Fiber dissection techniques described by Klingler were adopted. The primary dissection tools were handmade, thin, and wooden and curved metallic spatulas with tips of various sizes. Lateral and inferior temporal approaches were made and the optic fiber tracts were dissected.
Resections that extend through the roof of the temporal horn more than 30 mm behind the temporal pole cross the Meyer's loop. In the middle temporal gyrus approach, resection that is taken through the lateral wall of the temporal horn more than 55-60 mm behind the temporal pole may cross the optic radiation during their course here on the lateral wall.
The presented fiber dissection study clarifies the relationship of optic radiation. Such fiber dissection studies are only few in the literature.
运用纤维解剖技术，我们旨在研究视辐射的纤维束。我们重点关注其走行、长度、与侧脑室的解剖关系以及这些发现对该区域手术的相关性。
使用五例先前冷冻并经福尔马林固定的人体尸体脑标本。解剖操作在手术显微镜下进行。采用克林格勒描述的纤维解剖技术。主要解剖工具是自制的、薄的、木质和弯曲的金属刮匙，其尖端大小各异。采用颞叶外侧和颞下入路并对视神经纤维束进行解剖。
在颞极后方超过30毫米处延伸穿过颞角顶部的切除术会穿过迈耶袢。在颞中回入路中，在颞极后方超过55 - 60毫米处通过颞角外侧壁进行的切除术在其沿外侧壁走行过程中可能会穿过视辐射。
所呈现的纤维解剖研究阐明了视辐射的关系。此类纤维解剖研究在文献中较少见。
