视交叉和视交叉后视觉通路的探索是基于磁共振成像。双颞侧偏盲提示视交叉病变，而同侧偏盲则提示视交叉后视路病变。视交叉损害的原因主要是肿瘤。探查方案基于MRI，T1加权矢状面，然后T2和T1加权冠状面，有或无注射。在视交叉后综合征的情况下，MRI探查方案是缺陷发生类型和背景的函数。
The exploration of the chiasmal and retrochiasmal visual pathways is based on magnetic resonance imaging. A bitemporal hemianopsis suggests a lesion of the optic chiasm while homonymous lateral hemianopsis should lead to a search for a lesion of the retrochiasmal visual pathways. The causes of chiasmal impairment are mainly tumoral. The exploration protocol is based on MRI with T1-weighted sagittal sections, then T2- and T1-weighted coronal sections with and without injection. In case of a retrochiasmal syndrome, the MRI exploration protocol is a function of the type of occurrence of the deficiency and the context.
