Autism spectrum conditions (ASC) are defined by criteria comprising impairments in social interaction and communication. Altered visual perception is one possible and often discussed cause of difficulties in social interaction and social communication. Recently, Ashwin et al. suggested that enhanced ability in local visual processing in ASC was due to superior visual acuity, but that study has been the subject of methodological criticism, placing the findings in doubt.
The present study investigated visual acuity thresholds in 24 adults with Asperger's syndrome and compared their results with 25 control subjects with the 2 Meter 2000 Series Revised ETDRS Chart.
The distribution of visual acuities within the two groups was highly similar, and none of the participants had superior visual acuity.
Superior visual acuity in individuals with Asperger's syndrome could not be established, suggesting that differences in visual perception in ASC are not explained by this factor. A continued search for explanations of superior ability in local visual processing in persons with ASC is therefore warranted.
自闭症谱系障碍（ASC）的定义标准包括社交互动和沟通方面的障碍。视觉感知的改变是导致社交互动和社交沟通困难的一个可能且经常被讨论的原因。最近，Ashwin 等人提出，ASC 中局部视觉处理能力增强是由于视觉敏锐度较高，但该研究受到了方法学上的批评，研究结果存在疑问。
本研究调查了 24 名阿斯伯格综合征成人的视力阈值，并将他们的结果与 25 名具有 2 米 2000 系列修订版 ETDRS 图表的对照组进行比较。
两组的视力分布高度相似，没有参与者具有较高的视力。
不能确定阿斯伯格综合征患者的视力是否较好，这表明 ASC 中的视觉感知差异不能用这一因素来解释。因此，有必要继续寻找解释 ASC 中个体局部视觉处理能力较强的原因。
