We report a case of cortical blindness occurring 7 days after acute CO poisoning with no other neurological or psychic deficits apart from denial of the blindness with visual confabulation and slight loss of retentive memory. There was scant correlation between the course of the clinical pattern, which cleared completely within 6 days, and the electroencephalographic pattern with marked and diffuse slowing, which did not recede completely during 3 months observation. CT scanning of the skull, initially within normal limits, displayed 2 weeks later a faint but diffuse hypodensity of the white substance, more marked in the occipital region, which was no longer present 80 days after the first scan.
我们报告一例急性一氧化碳中毒7天后发生皮质盲的病例，除了否认失明并伴有视觉虚构以及轻度近事记忆丧失外，无其他神经或精神缺陷。临床症状在6天内完全消失，而脑电图显示明显弥漫性减慢，在3个月的观察期内未完全消退，二者之间几乎没有相关性。最初颅骨CT扫描结果正常，2周后显示白质有轻微但弥漫性的低密度影，枕叶更明显，首次扫描80天后该低密度影消失。
