摘要
大脑接收的外界信息80%以上来源于视觉,视觉系统与脑的许多高级功能密切相关。大量的视觉信息从视网膜开始向大脑传递,最终产生感觉和认知。近视作为一种屈光异常状态,将会影响视觉信息的获得,并影响大脑对外部信息的分析及处理,从而影响个体对环境的适应。目前视觉行为学方法是研究视觉认知功能的工具,通过行为学方法可观察动物的识别能力、空间记忆力等方面的功能。研究近视与视觉认知的关系可加深对近视发生机制及其所产生影响的了解,为深入研究近视提供新的思路。
Brain receives more than 80% information from the vision. Visual sense is also associated with many physiological functions of brain. Visual information is transmitted from retina to brain, and eventually leads sensation and cognition. Myopia, a kind of ametropia, can affect not only the reception of visual information, but also the analysis and management of the information by brain and the individual ability of adaptation to environment. Measure of visual behavior as a method can be used for studying visual cognition. Through the animal＇s behavior, we can observe the animal＇s ability of cognition and identification, spatial memory and other aspects of the function. Study of the relationship between myopia and visual cognition can illustrate the effect of myopia on cognitive function and provide further theoretical basis and method for myopia research.
