双眼视,即双眼同时工作、协调和整合视觉信息的能力,能够产生单一、立体和深度感的视觉体验,近年来在认知心理学和神经科学研究中逐渐受到越来越多的重视,尤其是在探讨其与执行能力之间复杂关联的方面。执行能力作为一项至关重要的认知功能,涉及多个方面,包括注意力、工作记忆、决策和问题解决等,这些因素共同影响着个体在日常生活和工作中的表现和效率。当前的研究表明,双眼视不仅在视觉信息的处理上发挥着关键作用,还对个体的执行能力产生了显著的影响。双眼视异常群体(如斜视、弱视患者)在执行功能测试中普遍表现出反应抑制延迟、工作记忆容量降低等特征。然而,现有文献中关于双眼视与执行能力之间关系的研究,特别是基于神经机制及其临床影响的系统性分析仍显得相对不足。为此,本文通过对现有研究的综述,深入探讨双眼视在执行能力中的作用,详细分析其背后的神经机制,并讨论这些发现对临床实践可能产生的影响。此外,文章还提出了未来研究的方向,以期更全面地理解双眼视与执行能力之间复杂的交互关系,从而为相关领域的研究提供新的视角和思路,推动这一领域的进一步发展。
Binocular vision, the ability of both eyes to work simultaneously, coordinate, and integrate visual information, can produce a unified, three-dimensional, and depth-perceptive visual experience. In recent years, it has garnered increasing attention in cognitive psychology and neuroscience research, particularly in exploring its complex relationship with executive functions. Executive functions, as a crucial cognitive capability, encompass various aspects, including attention, working memory, decision-making, and problem-solving, all of which collectively influence an individual's performance and efficiency in daily life and work. Current research indicates that binocular vision plays a key role not only in processing visual information but also has a significant impact on an individual's executive functions. Groups with binocular vision abnormalities (such as strabismus and amblyopia patients) generally exhibit characteristics like delayed response inhibition and reduced working memory capacity in executive function tests. However, existing literature on the relationship between binocular vision and executive functions, especially systematic analyses based on neural mechanisms and their clinical implications, remains relatively insufficient. Therefore, this article reviews existing research to delve into the role of binocular vision in executive functions, analyzes the underlying neural mechanisms in detail, and discusses the potential clinical implications of these findings. Additionally, the article proposes future research directions to comprehensively understand the complex interplay between binocular vision and executive functions, aiming to provide new perspectives and ideas for research in related fields and promote further development in this area.
目的: 探讨儿童双目视力筛查仪在先天性白内障中的应用。 方法: 本文为回顾性分析,选择 2017 年 7 月 至 2018 年 5 月在厦门市儿童医院眼科的 3 个月至 2 岁婴幼儿 336 例(672眼),均由2个固定的医生分别采用小瞳孔红光反射及儿童双目视力筛查仪检查,同时详细记录病史资料。所有患儿均给予裂隙灯检查、复方托品卡胺散瞳后行眼底检查,对眼底无法窥入的者必要时给予眼部B超检查或眼部MRI检查,以排除眼底病变。结果:依据2009年出版的第5版《Harley’s小儿眼科学》的先天性白内障临床分类方法,本组病例中先天性白内障的类型依次为皮质(核)白内障2 7例(35眼),其中胚胎核2例( 4眼),板层2 3例(29眼),核性2例( 2眼);囊膜性白内障1 9例(28眼),缝合性白内障2例( 4眼),极性白内障3例( 6眼),全白内障2例( 3眼)。儿童双目视力筛查仪筛查出先天性白内障的灵敏度为81.58%,特异度为79.87%,诊断符合率为80.06%;红光反射筛查的先天性白内障的灵敏度为51.32%,特异度为69.97%,诊断符合率为67.86%;两组结果比较均有统计学意义。儿童双目视力筛查仪对皮质(核)性白内障筛查率为97.14%,而红光反射的筛查率为37.14%,结果比较具有统计学意义。结论:儿童双目视力筛查仪在先天性白内障筛查中,具有低漏诊率和误诊率,较高的诊断一致性的优势,尤其对皮质(核)性白内障有高的检出率,将有利于在日常儿童眼保健的辅助筛查工作中,及早发现先天性白内障患儿。
Objective: To explore the application of children’s binocular vision screening instrument in screening congenital cataract. Methods: This was a retrospective analysis of 336 infants aged 3 months to 2 years (672 eyes) who were admitted to the Ophthalmology Department of Xiamen Children's Hospital from July 2017 to May 2018. They were examined by two fixed doctors with the pupil red light reflex and binocular vision screening instrument, and the medical history was recorded in details. All the children received slit lamp examination, compound tropicamide mydriasis and fundus examination. If necessary, the children who could not see fundus were given with B-ultrasonic examination or MRI examination. Results: According to the clinical classification of congenital cataracts published in the 5th edition of Harley’s pediatric ophthalmology in 2009, In this group, there were 27 cases (35 eyes) of congenital cataract, including 2 cases (4 eyes) of embryonic nucleus, 23 cases (29 eyes) of lamellar layer, 2 cases (2 eyes) of nuclear cataract, 19 cases (28 eyes) of capsular cataract, 2 cases (4 eyes) of suture cataract, 3 cases (6 eyes) of polar cataract and 2 cases (3 eyes) of total cataract. The sensitivity of children’s binocular vision screening instrument screening congenital cataract was 81.58%, the specificity was 79.87%, and the diagnostic coincidence rate was 80.06%; the sensitivity of red reflection screening congenital cataract was 51.32%, the specificity was 69.97%, and the diagnostic coincidence rate was 67.86%; the results of the two groups were statistically significant. The screening rate of children's binocular vision screening instrument for cortical (nuclear) cataract was 97.14%, while that of red reflex was 37.14%. The results were statistically significant. Conclusion: In the screening of congenital cataract, the binocular vision screening instrument for children has the advantages of low missed diagnosis rate, high misdiagnosis rate and high diagnostic consistency, especially for cortical (nuclear) cataract. It is helpful to find the congenital cataract early in the auxiliary screening of children’cares eye health
