对在智利 10 所盲人学校注册的 421 名儿童中的 318 名（76%）进行了检查。其中84%有严重视力丧失（严重视力障碍或失明），其中遗传因素占29.6%，宫内因素占8.2%，围产期因素占22.5%，儿童因素占11.2%。 28.5%的人无法确定病因。早产儿视网膜病变 (ROP) 占所有严重视力丧失儿童的 17.6%；按年龄组进行的数据分析表明，ROP 正在成为日益重要的失明原因。据估计，智利有一半严重视力丧失的儿童的失明原因是可以避免的。根据可能的控制策略对研究结果进行了讨论。
Three hundred and eighteen of 421 children (76 per cent) registered in Chile's 10 schools for the blind were examined. 84 per cent of these had severe visual loss (severe visual impairment or blindness), which was attributable to hereditary factors in 29.6 per cent, intra-uterine factors in 8.2 per cent, perinatal factors in 22.5 per cent and childhood factors in 11.2 per cent. The aetiology could not be determined in 28.5 per cent. Retinopathy of prematurity (ROP) accounted for 17.6 per cent of all children with severe visual loss; analysis of data by age-group suggested that ROP is becoming an increasingly important cause of blindness. It is estimated that one-half of the children with severe visual loss in Chile have avoidable causes of blindness. The findings are discussed in the light of possible control strategies.
