Patients with Down's syndrome usually have mild and pleasant temperaments, rarely exhibiting temper tantrums or behavioral problems. Blindness occurs in 5% of these patients. When present, it is usually due to keratoconus and cataracts and their associated complications. In this paper the authors report a case of self-induced ocular blindness that apparently resulted from the patient's severe mental retardation. To their knowledge, this has not been described in Down's syndrome.
唐氏综合征患者通常性情温和、讨人喜欢，很少发脾气或出现行为问题。这些患者中有5%会失明。失明通常是由圆锥角膜、白内障及其相关并发症引起的。在本文中，作者报告了一例因患者严重智力迟钝而导致的自我诱发失明病例。据他们所知，唐氏综合征患者中尚未有过此类报道。
