摘要

摘要:重要性:更新对低视力和失明的患病率和发病率的估计,以告知政策制定者,制定计划以满足未来低视力康复服务的需求。

目的:提供对美国低视力和失明的发病率和患病率的最新估计。

设计、设置和参与者:在2007-2008年的国家健康和营养检查调查中,视敏度作为年龄的函数,以种族和民族代表的形式,对视力进行测量,以评估视力损害的发生率和发病率。数据来自6016名调查对象,年龄从18岁到45岁不等,以获得不同年龄组的患病率评估。根据指数模型估计适合年龄患病率的函数(在年龄5年的眼睛中指定),老年人低视力的发病率和患病率(视力较好的那只眼的最佳矫正视力(BCVA) < 20/40< 20/60)和失明发病率和患病率(BCVA20/200。根据2010年的美国人口普查数据,利用应用于人口普查预测的比率模型,以估计美国2017年、2030年和2050年的低视力和失明的患病率和年发病率。数据收集的时间范围自2007111日至20081031日。数据分析于2016331日至2017319日进行。

主要结果和措施:美国低视力和失明的患病率和发病率。

结果:在研究的6016人中,1714(28.4%)年龄小于18岁,2358(39.1%)年龄在18岁至44岁之间,而1944(32.3%)年龄在45岁或以上。共有2888名男性(48%)3128名女性(52%)参加。低视力和失明的多发于在老年人群体(45),到2017年在美国估计有3 894 406(95% CI,3 034 442 - 4 442 549) 最佳矫正视力(BCVA)不到20/40,1 483 703(95%可信区间,968 656 - 2 656 513) 最佳矫正视力(BCVA)不到20/60,1 082 790(95%可信区间,637 771 - 1 771 864)的最佳矫正视力(BCVA)20/200或更少。估计2017年度发病率(2010年人口普查数据预计)低视力和失明的老年人(45)在美国是481 970(95%可信区间,375 541 - 601 787) 最佳矫正视力(BCVA)不到20/40,183 618(95%可信区间,119 878 - 293 367) 最佳矫正视力(BCVA)不到20/60,134 002(95%可信区间,83 383 - 215 567)的最佳矫正视力(BCVA) 20/200或更少。每个最佳矫正视力(BCVA)标准的年发病率为总患病率的12.4%

结论和相关性:低视力和失明影响了美国老年人口的很大一部分。对视力损害的患病率和年发病率的估计,协助政策规划人员为这个一旦丧失足以改变生活的功能分配和发展资源。

 

Importance:Updated estimates of the prevalence and incidence rates of low vision and blindness are needed to inform policy makers and develop plans to meet the future demands for low vision rehabilitation services.Objective:To provide updated estimates of the incidence and prevalence of low vision and blindness in the United States.Design, Setting, and Participants:Visual acuity measurements as a function of age from the 2007-2008 National Health and Nutrition Examination Survey, with representation of racial and ethnic groups, were used to estimate the prevalence and incidence of visual impairments. Data from 6016 survey participants, ranging in age from younger than 18 years to older than 45 years, were obtained to estimate prevalence rates for different age groups. Incidence and prevalence rates of low vision (best-corrected visual acuity [BCVA] in the better-seeing eye of <20/40 and <20/60) and blindness (BCVA of 20/200) in older adults were estimated from exponential models, fit to prevalence rates as a function of age (specified in 5-year age bins). The prevalence and annual incidence of low vision and blindness in theUnited Stateswere estimated, using the 2010UScensus data by age, from the rate models applied to the census projections for 2017, 2030, and 2050. Data were collected from November 1, 2007, to October 31, 2008. Data analysis took place from March 31, 2016, to March 19, 2017.Main Outcomes and Measures:Prevalence and incidence rates of low vision and blindness in the United States.Results:Of the 6016 people in the study, 1714 (28.4%) were younger than 18 years of age, 2358 (39.1%) were 18 to 44 years of age, and 1944 (32.3%) were 45 years of age or older. There were 2888 male (48%) and 3128 female (52%) participants. The prevalence of low vision and blindness for older adults (45 years) in the United States in 2017 is estimated to be 3  894  406 persons (95% CI, 3  034  442-4  862  549 persons) with a BCVA less than 20/40, 1  483  703 persons (95% CI, 968  656-2  370  513 persons) with a BCVA less than 20/60, and 1  082  790 persons (95% CI, 637  771-1  741  864 persons) with a BCVA of 20/200 or less. The estimated 2017 annual incidence (projected from 2010 census data) of low vision and blindness among older adults (45 years) in the United States is 481  970 persons (95% CI, 375  541-601  787 persons) with a BCVA less than 20/40, 183  618 persons (95% CI, 119  878-293  367 persons) with a BCVA less than 20/60, and 134  002 persons (95% CI, 83  383-215  567 persons) with a BCVA of 20/200 or less. The total annual incidence for each BCVA criterion is 12.4% of the total prevalence.Conclusions and Relevance:Low vision and blindness affect a substantial portion of the older population in theUnited   States. Estimates of the prevalence and annual incidence of visual impairment assist policy planners in allocating and developing resources for this life-changing loss of function.
