背景虽然失明和视力障碍的患病率随着年龄的增长而增加，但大多数眼科疾病的调查不包括养老院居民。我们对居住在巴尔的摩地区疗养院的40岁或以上的人进行了一项基于人群的患病率调查。在30家疗养院的738名合格受试者中，499名（67.6%）参与了这项研究。他们接受了眼睛检查和视力测试，并接受了详细的面谈。非参与者更有可能是老年人，是白色，在简易精神状态检查中得分较低。双眼失明（视力小于或等于20/200）的患病率为17.0%。视力损害的患病率（20/200）为18.8%。失明的频率从60岁以下的15.2%上升到90岁以上的28.6%。年龄调整后的失明患病率黑人比白人高50%（P
Background. Although the prevalence of blindness and visual impairment increases with age, most surveys of ocular disease do not include nursing home residents.Methods. We conducted a population-based prevalence survey of persons 40 years of age or older residing in nursing homes in the Baltimore area. Of 738 eligible subjects in 30 nursing homes, 499 (67.6 percent) participated in the study. They had their eyes examined and their visual acuity tested and were interviewed in detail. The nonparticipants were more likely to be older, to be white, and to have lower scores on the Mini-Mental State Examination.Results. The prevalence of bilateral blindness (visual acuity less than or equal to 20/200) was 17.0 percent. The prevalence of visual impairment (20/200) was 18.8 percent. The frequency of blindness increased from 15.2 percent among those under 60 years of age to 28.6 percent among those 90 or older. The age-adjusted prevalence of blindness was 50 percent higher among blacks than among whites (P
