Abstract

Amblyopia has effects on vision that extend from the processing of low-level visual features to higher level functions such as visual attention. In this narrative review, we focus on the impact of amblyopia on visual attention. A structured literature search revealed 28 articles reporting comparisons between amblyopia and normal vision control groups for a variety of visual attention tasks. Several of these articles also included neuroimaging measures. A review of these articles suggested that amblyopia does not affect behavioral performance of tasks with a low attentional load, such as cuing tasks, but deficits emerge for tasks with high demands on visual attention such as multiple object tracking. Deficits are not limited to the amblyopic eye but are also evident under fellow eye and binocular viewing conditions suggesting that abnormal early binocular visual experience can fundamentally alter the development of visual attention. Overall, the current literature suggests that amblyopia is associated with reduced visual attention resources. We raise the possibility that this attention resource deficit may be partially associated with an attentional demand for suppression of the amblyopic eye.

弱视的注意力缺陷：一个叙述性回顾

弱视对视觉的影响从低级视觉特征的处理延伸到高级功能，如视觉注意。在这篇叙述综述中，我们主要关注弱视对视觉注意的影响。一项结构化的文献检索显示，有28篇文章报道了弱视和正常视力控制组在各种视觉注意任务上的比较。其中一些文章还包括神经成像测量。对这些文章的回顾表明，弱视不影响低注意力负荷任务（如提示任务）的行为表现，但在视觉注意力要求高的任务（如多目标跟踪）中出现缺陷。这种缺陷不仅局限于弱视眼，在同眼和双眼观看条件下也很明显，这表明早期双眼视觉体验的异常可以从根本上改变视觉注意的发展。总的来说，目前的文献表明弱视与视觉注意力资源减少有关。我们提出这种注意力资源不足可能部分与抑制弱视的注意力需求有关。

期刊介绍： Vision Research is a journal devoted to the functional aspects of human, vertebrate and invertebrate vision and publishes experimental and observational studies, reviews, and theoretical and computational analyses. Vision Research also publishes clinical studies relevant to normal visual function and basic research relevant to visual dysfunction or its clinical investigation. Functional aspects of vision is interpreted broadly, ranging from molecular and cellular function to perception and behavior. Detailed descriptions are encouraged but enough introductory background should be included for non-specialists. Theoretical and computational papers should give a sense of order to the facts or point to new verifiable observations. Papers dealing with questions in the history of vision science should stress the development of ideas in the field.
