Recent research has identified a low-level transient visual system deficit in patients with reading disability. This deficit has been shown to have consequences on higher level perceptual and cognitive functions, including reading. This new information provides optometrists with a theoretical framework to expand the understanding of the relationship between vision and reading. In this paper, traditional concepts are described and an extensive literature review is provided. The impact of these processing deficits on reading performance is discussed based on metacontrast masking and foveal-parafoveal sequential attention models of reading. Clinical implications of transient system function in other clinical entities are also provided.
最近的研究已经确定阅读障碍患者存在低水平的短暂视觉系统缺陷。已证明这种缺陷会对包括阅读在内的更高层次的感知和认知功能产生影响。这一新信息为验光师提供了一个理论框架，以扩展对视力与阅读之间关系的理解。本文描述了传统概念并提供了广泛的文献综述。基于阅读的元对比掩蔽和中央凹-副中央凹顺序注意模型，讨论了这些处理缺陷对阅读表现的影响。还提供了短暂系统功能在其他临床实体中的临床意义。
