Rationale: It is known that visual field defects (VFDs) in the upper quadrant was demonstrated after epilepsy surgery for temporal lobe epilepsy. In our hospital, pre-/post- surgical evaluation of visual field was performed in all patients underwent epilepsy surgery. Details of VFDs were summarized. Methods: 37 patients underwent epilepsy surgery, either the anterior temporal lobectomy (ATL) or the selective amygdalohippocampectomy (SAH) was selected, for temporal lobe epilepsy. In all patients, Humphrey Visual Field testing and Goldmann Visual Field testing were performed before and after surgery. Results: A VFD in the upper quadrant was demonstrated in 30 (81.1%) of the 37 patients after surgery. VFDs by type of operation was 24 (82.8%) of 29 patients underwent ATL, 6 (75%) of 8 patients underwent SAH. In the observational evaluation, the range of VFDs tended to be narrower in SAH patients than in ATL patients. Conclusions: It was confirmed that VFDs occurred relatively frequently regardless of the operation type. VFDs is hardly noticed and does not lower ADL, but it should be fully explained as postoperative complications. Funding: None
