Individuals with cerebral visual impairment (CVI) frequently report challenges with face recognition, and subsequent difficulties with social interactions. However, there is limited empirical evidence supporting poor face recognition in individuals with CVI and the potential impact on social-emotional quality-of-life factors. Moreover, it is unclear whether any difficulties with face recognition represent a broader ventral stream dysfunction. In this web-based study, data from a face recognition task, a glass pattern detection task, and the Strengths and Difficulties Questionnaire (SDQ) were analyzed from 16 participants with CVI and 25 controls. In addition, participants completed a subset of questions from the CVI Inventory to provide a self-report of potential areas of visual perception that participants found challenging. The results demonstrate a significant impairment in the performance of a face recognition task in participants with CVI compared to controls, which was not observed for the glass pattern task. Specifically, we observed a significant increase in threshold, reduction in the proportion correct, and an increase in response time for the faces, but not for the glass pattern task. Participants with CVI also reported a significant increase in sub-scores of the SDQ for emotional problems and internalizing scores after adjusting for the potential confounding effects of age. Finally, individuals with CVI also reported a greater number of difficulties on items from the CVI Inventory, specifically the five questions and those related to face and object recognition. Together, these results indicate that individuals with CVI may demonstrate significant difficulties with face recognition, which may be linked to quality-of-life factors. This evidence suggests that targeted evaluations of face recognition are warranted in all individuals with CVI, regardless of their age.
患有脑性视觉障碍（CVI）的个体经常报告在人脸识别方面存在困难，进而在社交互动中遇到后续问题。然而，支持CVI个体人脸识别能力差及其对社会情感生活质量因素潜在影响的实证证据有限。此外，尚不清楚人脸识别方面的任何困难是否代表更广泛的腹侧流功能障碍。在这项基于网络的研究中，分析了16名CVI参与者和25名对照组在人脸识别任务、玻璃图案检测任务以及优势与困难问卷（SDQ）中的数据。此外，参与者完成了CVI量表中的一部分问题，以自我报告他们认为具有挑战性的视觉感知潜在领域。结果表明，与对照组相比，CVI参与者在人脸识别任务中的表现存在显著受损，而在玻璃图案任务中未观察到这种情况。具体而言，我们观察到面部识别的阈值显著增加、正确比例降低以及反应时间增加，而玻璃图案任务则没有。在调整年龄的潜在混杂效应后，CVI参与者在SDQ的情绪问题和内化得分子量表上也报告有显著增加。最后，CVI个体在CVI量表项目上也报告了更多困难，特别是五个问题以及与面部和物体识别相关的问题。总之，这些结果表明，CVI个体在人脸识别方面可能存在显著困难，这可能与生活质量因素有关。这一证据表明，无论年龄大小，所有CVI个体都有必要进行针对性的人脸识别评估。
