Recently, there has been heightened interest in suggestions of enhanced visual acuity in autism spectrum disorders (ASD) which was sparked by evidence that was later accepted to be methodologically flawed. However, a recent study that claimed children with ASD have enhanced visual acuity (Brosnan et al. in J Autism Dev Disord 42:2491-2497, 2012) repeated a critical methodological flaw by using an inappropriate viewing distance for a computerised acuity test, placing the findings in doubt. We examined visual acuity in 31 children with ASD and 33 controls using the 2 m 2000 Series Revised Early Treatment Diabetic Retinopathy Study chart placed at twice the conventional distance to better evaluate possible enhanced acuity. Children with ASD did not demonstrate superior acuity. The current findings strengthen the argument that reports of enhanced acuity in ASD are due to methodological flaws and challenges the reported association between visual acuity and systemising type behaviours.
最近，人们对自闭症谱系障碍（ASD）中视觉敏锐度提高的建议产生了浓厚的兴趣，这一兴趣源于后来被认为在方法上有缺陷的证据。然而，最近的一项研究声称，自闭症儿童具有较高的视觉敏锐度（Brosnan 等人，J Autism Dev Disord 42:2491-2497, 2012），该研究重复了一个关键的方法学缺陷，即使用不适当的计算机视力测试观看距离，使研究结果受到质疑。我们使用 2 米 2000 系列修订后的早期糖尿病视网膜病变研究图表，将其放置在常规距离的两倍处，以更好地评估可能的提高视力，对 31 名自闭症儿童和 33 名对照组儿童的视力进行了检查。自闭症儿童没有表现出较高的视力。目前的研究结果进一步证明了自闭症患者中视力提高的报告是由于方法学缺陷，同时也对视力和系统化行为之间的关联提出了质疑。
