摘要：

Eye-tracking studies have shown potential in effectively discriminating between autism spectrum disorder (ASD) and non-ASD groups. The main objective of the present study was to conduct a systematic review and meta-analysis of eye-tracking studies in adults with ASD. A total of 22 studies were included for meta-analysis. Eyes and Non-Social regions proved better for discriminating between ASD and non-ASD adults, while fixation duration seems to be the outcome to choose. Active engaged tasks seem to reduce differences between ASD and non-ASD adults, regardless of the emotional content of the stimuli/task. Proportional fixation duration on eyes and non-social areas in non-active tasks (e.g. free viewing) seems to be the best eye-tracking design for increasing the sensitivity and specificity in ASD adults.

眼动追踪研究已显示出有效区分自闭症谱系障碍 （ASD） 和非 ASD 组的潜力。本研究的主要目的是对成人 ASD 患者的眼动追踪研究进行系统评价和荟萃分析。共纳入22项研究进行meta分析。事实证明，眼睛和非社交区域更适合区分 ASD 和非 ASD 成年人，而注视持续时间似乎是可供选择的结果。积极的参与任务似乎减少了 ASD 和非 ASD 成年人之间的差异，无论刺激/任务的情感内容如何。在非活动任务（例如自由观看）中，按比例注视眼睛和非社交区域的持续时间似乎是增加 ASD 成人敏感性和特异性的最佳眼动追踪设计。
