Individuals with traumatic brain injury (TBI) manifest a wide range of visual dysfunctions. One of the most prevalent involves the oculomotor system, which includes version, vergence, and accommodation. However, until recently, there has been no comprehensive, computer-based program for remediation of these oculomotor deficits. We present such an oculomotor rehabilitation program that has been tested in a clinical trial in patients having TBI with a high degree of success based on before-and-after objective system recordings, performance measures, and related visual symptomotology. The basic program components include a versatile stimulus package incorporating the attentional paradigm of rapid serial visual presentation (RSVP), the ability to add a visual and/or auditory distractor to the training to increase difficulty level ("task loading"), automated assessment of RSVP errors, and automated assessment of visual performance over the training period. Program limitations and future directions are also considered.
创伤性脑损伤(TBI)患者表现出广泛的视觉功能障碍。其中最常见的一种涉及眼球运动系统,该系统包括眼球转动、辐辏和调节。然而,直到最近,还没有一个全面的、基于计算机的程序来纠正这些眼球运动缺陷。我们展示了这样一个眼球运动康复程序,该程序已在患有TBI的患者中进行了临床试验,并根据前后客观系统记录、性能指标和相关视觉症状学取得了高度成功。基本程序组件包括一个通用的刺激包,它结合了快速序列视觉呈现(RSVP)的注意力范式,能够在训练中添加视觉和/或听觉干扰物以提高难度水平(“任务负荷”),自动评估RSVP错误,以及在训练期间自动评估视觉性能。还考虑了程序的局限性和未来方向。
