目的：确定内伦敦老年人视力障碍和常见眼病的患病率。设计-横断面随机抽样调查。环境——内伦敦健康中心。对象——65岁及以上人群的随机样本，取自诊所的计算机年龄-性别登记。主要观察指标：双眼Snellen 6米距离视力和最佳单眼3米Sonksen-Silver视力，按照世界卫生组织标准（视力较好者小于3/60）和美国法定失明标准（视力较好者等于6/60或更低）、世界卫生组织标准（视力较好者等于6/18或更低）和美国标准（视力较好者小于6/12或20/40，但视力较好者大于6/60或20/200）对失明的流行程度进行分类。诊断视力丧失的主要原因，医院眼科服务的转诊指征，以及已知初级保健病例的比例。结果：288名符合条件的人中有207人（72%）接受了检查。17例（8%）居家受试者在家中接受检查。按照世界卫生组织的标准，失明的患病率为1%，按照美国的标准为3.9%。低视力（WHO标准）患病率为7.7%。视力障碍（美国标准）患病率为10.6%。白内障占低视力病例的75%。在16名低视力患者中，只有8名全科医生知道他们有眼睛问题。56名受试者（27%）可能受益于折射。与美国和芬兰的研究相比，这个样本的发病率更高，主要是由于致残性白内障的流行。结论——社区老年人中似乎有相当数量的未被发现的眼部疾病。
OBJECTIVE--To determine the prevalence of visual disability and common eye disease among elderly people in inner London. DESIGN--Cross sectional random sample survey. SETTING--Inner London health centre. SUBJECTS--Random sample of people aged 65 and over taken from practice's computerised age-sex register. MAIN OUTCOME MEASURES--Presenting binocular Snellen 6 m distance acuity and best monocular 3 m Sonksen-Silver acuity to classify prevalence of blindness by World Health Organisation criteria (less than 3/60 in better eye) and American criteria for legal blindness (better eye equal to 6/60 or less) and of low vision by WHO criteria (best acuity 6/18) and visual impairment by American criteria (less than 6/12 or 20/40 but greater than 6/60 or 20/200 in better eye). Principal cause of visual loss by diagnosis, referral indication by cause to hospital eye service, and proportion of cases known to primary care. RESULTS--207 of 288 (72%) eligible people were examined. 17 (8%) housebound subjects were examined at home. The prevalence of blindness was 1% by WHO criteria and 3.9% by American criteria. The prevalence of low vision (WHO criteria) was 7.7%. The prevalence of visual impairment (American criteria) was 10.6%. Cataract accounted for 75% of cases of low vision. Only eight out of 16 patients with low vision were known by their general practitioner to have an eye problem. 56 subjects (27%) would probably have benefited from refraction. Comparisons with studies in the United States and Finland suggested higher rates in this sample, mainly due to the prevalence of disabling cataract. CONCLUSION--There seems to be a considerable amount of undetected ocular disease in elderly people in the community.
