背景：有关致盲原因的大部分信息来自对特殊教育儿童的检查。为了获得更具代表性的儿童人群样本，通过培训当地志愿者担任主要信息者(KIS)，开发了一种新的确定重度视障(SVI)或盲人(BL)儿童的方法。目的：比较KIS招募的儿童的人口学和致盲原因与其他确定方法的差异。利用三个来源确定病例：盲人学校(SPEDU)、以社区为基础的康复方案(CBR)和KIS。所有数据均采用WHO/PBL标准眼科检查记录。约800名KI接受了培训。大多数儿童是被KIS招募的(64.3%)。KIS招募的儿童更有可能是女性(优势比(OR)1.6，p
Background: Most information on the causes of blindness has come from examining children in special education. To obtain a more representative population-based sample of children, a novel method was developed for ascertaining severe visually impaired (SVI) or blind (BL) children by training local volunteers to act as key informants (KIs).Objective: To compare the demography and cause of blindness in children recruited by KIs with other ascertainment methods.Method: Children with SVI/BL were recruited in all 64 districts of Bangladesh. Three sources for case ascertainment were utilised: schools for the blind (SpEdu), community-based rehabilitation (CBR) programmes and KIs. All data were recorded using the standard WHO/PBL Eye Examination Record.Results: 1935 children were recruited. Approximately 800 KIs were trained. The majority of the children were recruited by the KIs (64.3%). Children recruited by KIs were more likely to be female (odds ratio (OR) 1.6, p
