摘要: Importance Updated estimates of the prevalence and incidence rates low vision blindness are needed to inform policy makers develop plans meet future demands for rehabilitation services. Objective To provide updated in United States. Design, Setting, Participants Visual acuity measurements as a function age from 2007-2008 National Health Nutrition Examination Survey, with representation racial ethnic groups, were used estimate visual impairments. Data 6016 survey participants, ranging younger than 18 years older 45 years, obtained different groups.

There 2888 male (48%) 3128 female (52%) participants. The adults (≥45 years) States 2017 is estimated be 3 894 406 persons (95% CI, 3 034 442-4 862 549 persons) BCVA less 20/40, 1 483 703 968 656-2 370 513 20/60, 1 082 790 637 771-1 741 864 20/200 less. annual (projected 2010 census data) among 481 970 375 541-601 787 183 618 119 878-293 367 134 002 83 383-215 567 total each criterion 12.4% prevalence.
