Visual field defects (VFDs) produced by temporal lobe resections provide valuable information on the retinotopic organization of the optic radiations. The results of this systematic review of the literature will be translated into a revised--and evidence-based--map of the retinotopic anatomy of the anterior optic radiations.
Recent studies provide best evidence by combining automatic static perimetry and modern imaging techniques. VFDs occur in 83% of patients undergoing temporal lobectomy. There is a significant correlation between size of resection and amount of VFD. Most defects appear incongruous. Macular involvement is seen in more than 50% of cases. The inferolateral defect border is of a sloping nature and sometimes crosses the horizontal meridian. On the basis of these findings, the classical theory on the retinotopic anatomy of the optic radiation should be revised.
This article systematically reviews the literature on VFDs after temporal lobe resection. Frequency, size, congruity, macular involvement and defect borders are related to size of resection. The classical theory on the retinotopic organization of the anterior optic radiations should be revised.
颞叶切除术所导致的视野缺损（VFDs）为视辐射的视网膜定位组织提供了有价值的信息。本系统文献综述的结果将被转化为一份经过修订的、基于证据的前视辐射视网膜定位解剖图谱。
近期研究通过结合自动静态视野检查法和现代成像技术提供了最佳证据。83%接受颞叶切除术的患者会出现视野缺损。切除范围与视野缺损程度之间存在显著相关性。大多数缺损表现为不一致性。超过50%的病例可见黄斑受累。下外侧缺损边界呈倾斜状，有时会越过水平子午线。基于这些发现，对视辐射视网膜定位解剖的经典理论应予以修订。
本文系统综述了颞叶切除术后视野缺损的相关文献。频率、大小、一致性、黄斑受累情况和缺损边界与切除范围相关。前视辐射视网膜定位组织的经典理论应予以修订。
