A developmental framework for evaluation and treatment of visual perceptual deficits in adults with acquired brain injury is presented. The framework is based on a review of research conducted on post-cerebrovascular accident subjects and subjects with traumatic brain injuries. Visual perceptual skill is conceptualized as a hierarchy of skill levels that interact and subserve each other. Higher level skills evolve from integration of lower level skills and are subsequently affected by disruption of lower level skills. Oculomotor control, visual field, and acuity form the foundation skills, followed by visual attention, scanning, pattern recognition, memory, and visual cognition. Brain injury can affect the integrity and interaction of each skill level and affect daily living function. Application of this framework dictates a bottom-up approach to evaluation and treatment, emphasizing identification and remediation of deficits in lower level skills to allow normal integration of higher level skill.
本文提出了一个针对后天性脑损伤成人视觉感知缺陷评估与治疗的发展框架。该框架基于对脑血管意外患者和创伤性脑损伤患者的研究综述。视觉感知技能被概念化为一个相互作用且相互支持的技能水平层次结构。较高水平的技能由较低水平技能的整合演变而来，随后会受到较低水平技能中断的影响。眼球运动控制、视野和视力构成基础技能，其次是视觉注意力、扫视、模式识别、记忆和视觉认知。脑损伤会影响每个技能水平的完整性和相互作用，并影响日常生活功能。该框架的应用要求采用自下而上的评估和治疗方法，强调识别和纠正较低水平技能的缺陷，以实现较高水平技能的正常整合。
