摘　　要：视觉损伤是精神分裂症的重要特征之一,几乎所有视觉处理领域都存在缺陷,研究最多的包括对比敏感度、空间频率处理、视觉掩蔽、运动知觉及知觉组织等。这些视觉加工障碍具有潜在的临床意义,早期视觉处理的缺陷会导致更高层次的认知障碍。目前对精神分裂症视觉加工障碍的研究相对较少。现将对精神分裂症视觉加工相关的心理、物理学和神经影像学研究做一综述,探讨精神分裂症视觉加工方面的损害情况及相关的脑机制。Visual impairment is one of the most important characteristics of schizophrenia.Almost all visual processing fields have defects.The most studied areas include contrast sensitivity,spatial frequency processing,visual masking,motion perception and perceptual organization.These visual processing disorders have potential clinical significance,and the defects of early visual processing will lead to higher-level cognitive impairment.At present,there are relatively few studies on visual processing disorders in schizophrenia.This paper reviews the psychological,physical and neuroimaging research related to visual processing in schizophrenia,and explore the damage of visual processing in schizophrenia and its related brain mechanism.
