Four thousand, seven hundred and fifty-nine form 1 intermediate school children (aged 11 years) in the south Auckland health district were screened in 1987. There were 88 (1.8%) new visual defects detected (defined as a visual acuity (VA) of 6/12 or worse in one or both eyes), while 103 (2.2%) wore glasses and a further 22 (0.5%) did not have their glasses available at the time of the VA test. The total prevalence of screening visual defects was 4.5%. A survey was carried out of those pupils who failed the VA screening test in the previous year and those recorded as wearing glasses. Sixty-seven (76%) of 88 children with newly detected visual defects were interviewed. An abnormal VA test was confirmed in 59 (88%), of which 39 (66%) required treatment. Thirty were prescribed glasses, of which 27 purchased them, but at the time of interview nine did not have them available. Twenty-one (20%) of the 103 children tested with glasses failed the VA test. Twenty-two children had glasses but were not wearing them at the time of the VA test. Only three of these children had a VA better than 6/12 bilaterally. These results highlight the importance of the vision screening programme in this age group and the follow up of children with known visual defects.
1987年，对奥克兰南区健康区的4759名一年级中学生（11岁）进行了筛查。共检测出88例（1.8%）新发视力缺陷（定义为单眼或双眼视力（VA）为6/12或更差），103例（2.2%）佩戴眼镜，另有22例（0.5%）在视力测试时未佩戴眼镜。筛查出的视力缺陷总患病率为4.5%。对前一年视力筛查测试未通过的学生以及记录为佩戴眼镜的学生进行了调查。88例新发现视力缺陷的儿童中有67例（76%）接受了访谈。59例（88%）确认视力测试异常，其中39例（66%）需要治疗。30例被开了眼镜处方，其中27例购买了眼镜，但在访谈时9例未佩戴。103例佩戴眼镜测试的儿童中有21例（20%）视力测试未通过。22名儿童有眼镜，但在视力测试时未佩戴。这些儿童中只有3例双眼视力优于6/12。这些结果凸显了该年龄组视力筛查计划以及对已知视力缺陷儿童进行随访的重要性。
