The rate of occurrence of correctable undetected visual acuity deficit (CUVAD) in a population of patients aged 65 and over was investigated, using a pinhole screening method, to compare the sociodemographic and optical eye care habits of patients with or without a functionally significant CUVAD. Of 136 patients 46 (34%) were found to have a functionally significant CUVAD in one or both eyes which was not significantly associated with optician or general practitioner contact, age, sex, social class, living situation, or number of medications. Half the patients with significant CUVAD had not attended for 2 years mainly because of financial considerations. Three quarters attended of their own volition; only one in seven were prompted by opticians' postal invitations. It was concluded that a significant degree of CUVAD could be detected using a simple procedure which can be carried out by general practitioners as part of their general elderly health screen.
采用针孔筛查方法，对65岁及以上患者群体中可矫正未被发现的视力缺陷（CUVAD）的发生率进行了调查，以比较有或没有功能上显著的CUVAD的患者的社会人口统计学特征和眼部护理习惯。在136名患者中，46名（34%）被发现一只或两只眼睛存在功能上显著的CUVAD，这与是否接触验光师或全科医生、年龄、性别、社会阶层、生活状况或用药数量无显著关联。有显著CUVAD的患者中有一半两年未就诊，主要是出于经济考虑。四分之三的患者是自愿就诊的；只有七分之一是由验光师的邮寄邀请促使的。研究得出结论，使用一种简单程序可以检测到显著程度的CUVAD，该程序可由全科医生在对老年人进行常规健康筛查时实施。
