同向偏盲是由涉及视交叉后视觉通路或初级视觉皮层的单侧病变引起的。同向偏盲的常见原因包括中风、肿瘤和外伤。在本章中，我们首先回顾有助于定位病变并确定其原因的临床特征。接下来我们讨论同向偏盲的诊断评估，强调正式视野测试的重要性。我们列出了同名偏盲的原因，这些原因在神经影像学上产生很少或没有异常，包括偏头痛、癫痫发作、脑病和神经退行性疾病。最后，我们讨论同名偏盲对驾驶的影响和康复策略。
Homonymous hemianopia is caused by unilateral lesions involving the retrochiasmal visual pathways or primary visual cortex. Common causes of homonymous hemianopia include stroke, tumor, and trauma. In this chapter, we begin by reviewing the clinical features that can help to localize the lesion and determine its cause. We next discuss the diagnostic evaluation of homonymous hemianopia, emphasizing the importance of formal visual field testing. We list causes of homonymous hemianopia that produce minimal or no abnormalities on neuroimaging, which include migraine, seizures, encephalopathies, and neurodegenerative disorders. Lastly, we discuss the implications of homonymous hemianopia for driving and strategies for rehabilitation.
