综述目的视觉知觉缺陷在精神分裂症中得到了很好的证实，并与较差的结果和功能有关。通过训练在健康人群中可靠地证明了知觉功能的改善，但相对较少的研究检查了针对精神分裂症视觉处理功能障碍的方法。这篇综述总结了最近研究精神分裂症视觉修复的文献，指出了目前的局限性，并提出了进一步研究的方向。最近的发现现有的研究为精神分裂症视觉加工障碍的修复提供了支持，并证明改善发生在低水平、中等水平和更高水平的加工阶段。这些研究还表明，视觉过程的改善可能会推广到其他视觉感知和视觉认知功能。总结这些早期发现是有希望的，并证明了视觉矫正干预在精神分裂症中的有效性。然而，需要进行更多的实证研究，以确定当前干预措施的有效性，开发新的干预措施，隔离相关的变化机制，并促进将收益推广到其他职能。
Purpose of ReviewVisual perceptual deficits are well-established in schizophrenia and are related to poorer outcomes and functioning. Improvement in perceptual functioning with training has been reliably demonstrated in healthy populations, yet relatively few studies have examined approaches to targeting visual processing dysfunction in schizophrenia. This review summarizes recent literature investigating visual remediation in schizophrenia, identifies current limitations, and suggests directions for further research.Recent FindingsExisting studies provide support for the remediation of visual processing impairments in schizophrenia and demonstrate that improvement occurs at low-level, mid-level, and higher-level stages of processing. These studies also suggest that improvements in visual processes may generalize to other visual perceptual and visual cognitive functions.SummaryThese early findings are promising and demonstrate the effectiveness of visual remediation interventions in schizophrenia. However, more empirical research is needed to determine the effectiveness of current interventions, to develop new interventions, to isolate the relevant mechanisms of change, and to promote the generalization of gains to other functions.
