The elderly population in the United States (age 65 and older) is growing rapidly, estimated by the U.S. Census Department to reach 83.7 million by 2050.(1) Visual impairment increases with age among all racial and ethnic groups.(2) In the elderly, the most common culprits for vision loss are cataract, glaucoma, and age-related macular degeneration (AMD).(2) In the developed world, vision loss from cataract has been dramatically reduced by increased access to cataract surgery. However, AMD and glaucoma lead to irreversible vision loss without early diagnosis and intervention. In the U.S., cases of AMD are expected to double by 2050, reaching 17.8 million among patients age 50 or older.(3) Similarly, cases of glaucoma are expected to reach 5.5 million by 2050, an increase of over 90% from 2014.(3) The visually impaired elderly face disparities in access to eye care, and subsequent general medical and psychosocial complications.
美国老年人口(65岁及以上)正在迅速增长,据美国人口普查局估计,到2050年将达到8370万。(1)在所有种族和族裔群体中,视力障碍都随着年龄的增长而增加。(2)在老年人中,导致视力丧失的最常见原因是白内障、青光眼和年龄相关性黄斑变性(AMD)。(2)在发达国家,由于白内障手术可及性的提高,白内障导致的视力丧失已大幅减少。然而,AMD和青光眼如果不早期诊断和干预,会导致不可逆转的视力丧失。在美国,预计到2050年,AMD病例将增加一倍,在50岁及以上患者中达到1780万。(3)同样,预计到2050年,青光眼病例将达到550万,比2014年增加超过90%。(3)视力受损的老年人在获得眼科护理以及随后的一般医疗和心理社会并发症方面面临差异。
