Six children who sustained head trauma of varying degrees experienced self-limited cortical blindness--complete bilateral visual loss associated with normal pupillary responses to light. In five cases associated with relatively minor head trauma, full visual function returned within 24 hours. In the other case, associated with parietal and occipital contusions, the period of complete blindness was prolonged, lasting 1 week, followed by a striking recovery over an additional week. A bilateral inferior altitudinal visual field deficit has persisted over 6 years, with emergence of a complicated migraine syndrome. Sequential computed tomographic (CT) scans over a 4-year period demonstrate bioccipital and right parietal injury, correlating clinical and anatomic findings. This case is the first description of prolonged transient post-traumatic cortical blindness in a child with CT correlation. It underscores the clinical, radiographic, and pathophysiologic differences between syndromes of brief and prolonged transient post-traumatic cortical blindness in childhood.
六名遭受不同程度头部外伤的儿童出现了自限性皮质盲——双侧完全视力丧失且瞳孔对光反应正常。在五例与相对轻微头部外伤相关的病例中,全部视觉功能在24小时内恢复。在另一例与顶叶和枕叶挫伤相关的病例中,完全失明期延长,持续了1周,随后在接下来的一周内显著恢复。双侧下象限视野缺损持续了6年,并出现了复杂的偏头痛综合征。在4年期间的系列计算机断层扫描(CT)显示双侧枕叶和右侧顶叶损伤,将临床和解剖学发现联系起来。该病例是首例有CT相关性的儿童长时间短暂性创伤后皮质盲的描述。它强调了儿童短暂性和长时间短暂性创伤后皮质盲综合征在临床、影像学和病理生理学上的差异。
