目的：描述一组双侧视神经发育不全（ONH）盲童的认知和行为特征。方法：对1988-1998年出生的13例ONH盲童的病历、家长、教师和重复发育评估资料进行分析。所有儿童均具有中线畸形的神经影像学和/或激素证据。他们都是盲人，能用语言交流。结果：严重的情绪波动和发脾气是常见的，特别是在生命的最初几年。在后来的生活中，缓慢的节奏，低挫折容忍度和兴趣范围狭窄是常见的。6/13的儿童被诊断为自闭症，另外3名儿童被发现患有自闭症样症状（ALC）。其余4名儿童的行为不属于自闭症谱系。8名儿童的认知能力在正常或接近正常的范围内; 5名儿童患有智力迟钝。在所有认知亚组中均发现自闭症/ALC。所有的孩子表现出流利的讲话，其中，12个已经开始在预期的年龄交谈，但有明显的缺陷，在沟通能力。结论：这些孩子有一个共同的模式的行为特征，包括自闭症谱系障碍独立的智力能力。
Aim: To describe cognitive and behavioural characteristics in a group of blind children with bilateral optic nerve hypoplasia (ONH). Methods: Data from records, parents, teachers, and repeated developmental assessments of 13 blind children with ONH born in 1988-1998 were analysed. All children had neuroimaging and/or hormonal evidence of midline malformations. They were all blind and able to communicate with speech. Results: Severe mood swings and temper tantrums were common, especially during the first years of life. Later in life, sluggish tempo, low frustration tolerance and a narrow range of interests were common. Autism had been diagnosed in 6/13 children, autistic-like condition (ALC) was found in another three. The behaviour of the remaining four children was not within the autism spectrum. Eight children had cognitive capacities within the normal or near-normal range; five had mental retardation. Autism/ALC was found in all cognitive subgroups. All children exhibited fluent speech and, of these, 12 had started to talk at the expected age, but had clear deficiencies in communicative ability.Conclusion: These children had a common pattern of behavioural characteristics including autism spectrum disorders independent of intellectual capacities.
