摘要

后天性脑损伤患者曾报告过深度知觉障碍的主观主诉,但很少有人接受过客观评估来确认这些障碍。因此,目前缺乏有关后天性脑损伤患者主观深度知觉障碍与客观立体视觉障碍之间相关性的详细报告,尤其是那些有明确病变的病例。为了研究这种关系,我们招募了三名后天性脑损伤患者,他们在日常生活中都有深度知觉障碍和相关的困难。我们对他们进行了神经学、眼科学和神经心理学检查。我们还让他们进行了两种立体视觉测试:霍华德-多尔曼式立体视觉测试和拓普康新客观立体测试。然后,我们将测试结果与两个对照组进行了比较:一个是大脑右半球受损组,另一个是健康对照组。三名患者在两项立体视觉测试中的表现均严重受损。其中一名患者还出现了大脑复视。我们在楔叶和顶叶上部后段发现了这些缺陷的潜在神经基础,它们在会聚融合中起作用,位于背-背视觉通路的尾部区域,众所周知,背-背视觉通路不仅对视觉空间感知至关重要,而且在该通路的进一步过程中对伸手、抓握和做出手的姿势也至关重要。

Investigating the Link Between Subjective Depth Perception Deficits and Objective Stereoscopic Vision Deficits in Individuals With Acquired Brain Injury.

Individuals with acquired brain injury have reported subjective complaints of depth perception deficits, but few have undergone objective assessments to confirm these deficits. As a result, the literature currently lacks reports detailing the correlation between subjective depth perception deficits and objective stereoscopic vision deficits in individuals with acquired brain injury, particularly those cases that are characterized by a clearly defined lesion. To investigate this relationship, we recruited three individuals with acquired brain injury who experienced depth perception deficits and related difficulties in their daily lives. We had them take neurologic, ophthalmological, and neuropsychological examinations. We also had them take two types of stereoscopic vision tests: a Howard-Dolman-type stereoscopic vision test and the Topcon New Objective Stereo Test. Then, we compared the results with those of two control groups: a group with damage to the right hemisphere of the brain and a group of healthy controls. Performance on the two stereoscopic vision tests was severely impaired in the three patients. One of the patients also presented with cerebral diplopia. We identified the potential neural basis of these deficits in the cuneus and the posterior section of the superior parietal lobule, which play a role in vergence fusion and are located in the caudal region of the dorso-dorsal visual pathway, which is known to be crucial not only for visual spatial perception, but also for reaching, grasping, and making hand postures in the further course of that pathway.

期刊介绍: Cognitive and Behavioral Neurology (CBN) is a forum for advances in the neurologic understanding and possible treatment of human disorders that affect thinking, learning, memory, communication, and behavior. As an incubator for innovations in these fields, CBN helps transform theory into practice. The journal serves clinical research, patient care, education, and professional advancement. The journal welcomes contributions from neurology, cognitive neuroscience, neuropsychology, neuropsychiatry, and other relevant fields. The editors particularly encourage review articles (including reviews of clinical practice), experimental and observational case reports, instructional articles for interested students and professionals in other fields, and innovative articles that do not fit neatly into any category. Also welcome are therapeutic trials and other experimental and observational studies, brief reports, first-person accounts of neurologic experiences, position papers, hypotheses, opinion papers, commentaries, historical perspectives, and book reviews.
