We aimed to clarify the clinical characteristics that affect visual perception (VP) and elucidate lesion locations correlated with impaired VP. We reviewed 61 patients with stroke. Clinical assessments of a motor-free VP test were used to evaluate VP after stroke. Regression analyses were performed to examine predictors of impaired VP. We generated statistical maps of lesions related to impaired VP using voxel-based lesion symptom mapping (VLSM). The group of patients who had right hemispheric lesions had significantly low VP function. In a regression model, impaired VP was predicted by cognitive function, age, lesion volume, and right hemispheric lesion. Using VLSM, we found lesion location associated with impaired VP after adjusting for age, lesion volume, and Korean version of mini mental status exam. The results showed a lesion pattern with predominant distribution in the right parietal lobe and deep white matter. Age, lesion volume, and cognitive impairment affected the results of VP tests. Even after adjustments, we found that lesions responsible for impaired VP were located in the right parietal lobe and deep white matter. This result confirmed right hemispheric dominance for VP using VLSM. Clin. Anat. 32:689-696, 2019. © 2019 Wiley Periodicals, Inc.
我们旨在阐明影响视觉感知（VP）的临床特征，并阐明与 VP 受损相关的病变部位。我们回顾了 61 例脑卒中患者。使用无运动性 VP 测试的临床评估来评估卒中后的 VP。进行回归分析以检查 VP 受损的预测因素。我们使用基于体素的病变症状映射（VLSM）生成与 VP 受损相关的病变的统计图谱。右半球病变患者的 VP 功能明显降低。在回归模型中，认知功能、年龄、病变体积和右半球病变预测了 VP 受损。使用 VLSM，我们发现了在调整年龄、病变体积和韩国版简易精神状态检查后与 VP 受损相关的病变部位。结果显示病变模式以右顶叶和深部白质为主。年龄、病变体积和认知障碍影响 VP 测试的结果。即使经过调整，我们发现导致 VP 受损的病变位于右顶叶和深部白质。这一结果通过 VLSM 证实了 VP 的右半球优势。临床解剖学 32:689-696,2019.
