Neuropsychological outcome within two years after injury was determined in 159 head injured patients who were classified into three groups according to the presence of either unilateral, bilateral, or no visual field defects (VFDs). The VFDs occurred irrespective of injury severity as determined by the Glasgow coma scale, or social outcome as determined by the Glasgow outcome scale. Differences among the three visual field groups were obtained for several neuropsychological functions: intelligence, memory, learning, acquired verbal skills, visuospatial skills, and visuomotor speed. Patients with bilateral VFDs were more severely impaired neuropsychologically than those with unilateral or no VFDs. Occurrences of secondary complications (brain swelling, intracranial hypertension, and hyperemia) were more prevalent among the bilateral VFD cases. The findings suggested that bilateral VFDs may be indicators of increased brain damage from secondary insults.
对159名头部受伤患者进行了伤后两年内的神经心理学结果评估，这些患者根据是否存在单侧、双侧或无视野缺损（VFD）被分为三组。视野缺损的出现与由格拉斯哥昏迷量表确定的损伤严重程度或由格拉斯哥预后量表确定的社会结果无关。对三组视野缺损患者在几种神经心理学功能方面进行了比较：智力、记忆、学习、后天语言技能、视觉空间技能和视觉运动速度。双侧视野缺损患者在神经心理学方面的受损程度比单侧或无视野缺损患者更严重。双侧视野缺损病例中继发性并发症（脑肿胀、颅内高压和充血）的发生率更高。研究结果表明，双侧视野缺损可能是继发性损伤导致脑损伤增加的指标。
