An analysis of visual defects among 310 children referred from a vision screening of 2 178 7-year-old children revealed a 50% frequency of significant eye defects among the referrals (7% of screened children). Of the screened children, one group (1 530 children) had previous visual screening three years earlier. The other group (648 children) had no previous vision screening until the age of seven. A comparison between the two groups showed that the risk of finding a new significant eye disorder in a school entrant was more than 6 times greater for a child who was not examined in his preschool years, and the risk of finding an amblyopic child was more than 10 times greater. The results do indicate the need for continuation of the present vision screening program of pre-school children.
对从2178名7岁儿童视力筛查中转诊的310名儿童的视力缺陷分析显示，转诊儿童中严重眼部缺陷的发生率为50%（占筛查儿童的7%）。在筛查儿童中，一组（1530名儿童）三年前曾接受过视力筛查。另一组（648名儿童）直到7岁才进行过视力筛查。两组之间的比较表明，学龄前未接受检查的儿童进入学校后发现新的严重眼部疾病的风险要高出6倍多，发现弱视儿童的风险则高出10倍多。结果确实表明有必要继续实施目前的学龄前儿童视力筛查计划。
