In judging normalcy, surgeons rely on established facial anthropometric measures and proportions. However, there exists a range of "normal," and a degree of disproportion may be considered more attractive. The authors set out to determine how changes in only intercanthal distance affect the layperson's perception of beauty and personality traits of a face. The authors used Amazon.com's Mechanical Turk (MTurk), a crowdsourcing tool, to determine how changes in intercanthal distance affect overall perception of beauty and personality. MTurk respondents provided demographic information and were asked to survey 16 female subjects, each digitally edited to be hypoteloric or hyperteloric. Data were collected from 490 MTurk crowd raters. Paired t test analysis found that respondents perceived subjects to be more submissive, friendly, and attractive with increased intercanthal distance (P < 0.05). Women respondents were less likely to perceive change in regards to how unthreatening and how intelligent the subject appeared upon intercanthal widening (P < 0.05). Compared with Caucasian respondents, minorities (Asian- and African-American) were more likely to perceive difference in submissiveness, threat, intelligence, and attractiveness with increased intercanthal distance (P < 0.05). All respondents >46 years of age were less likely to perceive a change in any of the 7 traits upon intercanthal widening, compared with respondents between 18 and 25 years of age (P < 0.05). The layperson perceives significant increases in a female subject's submissivness, friendliness, and attractiveness with an intercanthal distance increase of 10% from normal. Surgeons should be aware of this when correcting hypertelorism, given the potential positive impact of a slightly increased intercanthal distance on perceived beauty and personality.
在判断面部是否正常时，外科医生依赖既定的面部人体测量方法和比例。然而，“正常”存在一定范围，一定程度的比例失调可能被认为更具吸引力。作者着手确定仅内眦间距的变化如何影响外行人对面部美感和个性特征的认知。作者使用亚马逊的土耳其机器人（MTurk）众包工具，来确定内眦间距的变化如何影响对美感和个性的整体认知。MTurk的受访者提供了人口统计学信息，并被要求对16名女性受试者进行评估，每个受试者都经过数字编辑，使其眼距过窄或过宽。从490名MTurk人群评分者那里收集了数据。配对t检验分析发现，随着内眦间距增加，受访者认为受试者更顺从、友好且有吸引力（P<0.05）。女性受访者不太可能察觉到内眦间距变宽时受试者的无威胁程度和聪慧程度有变化（P<0.05）。与白人受访者相比，少数族裔（亚裔和非裔美国人）更有可能察觉到内眦间距增加时受试者在顺从性、威胁性、聪慧程度和吸引力方面的差异（P<0.05）。与18至25岁的受访者相比，所有46岁以上的受访者不太可能察觉到内眦间距变宽时7种特征中任何一种的变化（P<0.05）。外行人认为，当女性受试者的内眦间距比正常增加10%时，其顺从性、友好性和吸引力会显著增加。鉴于内眦间距略有增加对感知到的美感和个性有潜在的积极影响，外科医生在矫正眼距过宽时应意识到这一点。
