Functional magnetic resonance imaging (fMRI), which is a technique useful for non-invasive mapping of brain function, is well suited for studying the visual system. This review highlights current clinical applications and research studies involving patients with visual deficits. Relevant reports regarding the investigation of the brain's role in visual processing and some newer fMRI techniques are also reviewed. Functional magnetic resonance imaging has been used for presurgical mapping of visual cortex in patients with brain lesions and for studying patients with amblyopia, optic neuritis, and residual vision in homonymous hemianopia. Retinotopic borders, motion processing, and visual attention have been the topics of several fMRI studies. These reports suggest that fMRI can be useful in clinical and research studies in patients with visual deficits.
功能磁共振成像（fMRI）是一种有助于对脑功能进行无创性图谱绘制的技术，非常适合用于研究视觉系统。本综述重点介绍了涉及视力缺陷患者的当前临床应用和研究。还回顾了有关大脑在视觉处理中的作用的调查以及一些更新的功能磁共振成像技术的相关报告。功能磁共振成像已用于脑部病变患者视觉皮层的术前图谱绘制，以及研究弱视、视神经炎和同侧偏盲患者的残余视力。视网膜定位边界、运动处理和视觉注意力一直是多项功能磁共振成像研究的主题。这些报告表明，功能磁共振成像在视力缺陷患者的临床和研究中可能有用。
