Vision & Eye Health
Dataset
2014-15 merged, 2016-17 merged. This dataset is a de-identified summary table of vision and eye health data indicators from NHIS, stratified by all available combinations of age group, race/ethnicity, gender, and risk factor. NHIS is an annual household survey conducted by the National Center for Health Statistics at CDC that monitors trends in illness, disabilities, and progress towards national health objectives. Approximate sample size is 35,000 households and 87,500 persons annually. NHIS data for VEHSS includes questions related to Visual Function. Data were suppressed for cell sizes less than 30 persons, or where the relative standard error more than 30% of the mean. Data will be updated as it becomes available. Detailed information on VEHSS NHIS analyses can be found on the VEHSS NHIS webpage (link). Additional information about NHIS can be found on the NHIS website (http://www.cdc.gov/nchs/nhis/about_nhis.htm). The VEHSS NHIS dataset was last updated in November 2019.

Vision & Eye Health
Dataset
1999-2008; 2005-2008. This dataset is a de-identified summary table of vision and eye health data indicators from NHANES, stratified by all available combinations of age group, race/ethnicity, gender, and risk factor. NHANES is a program of studies conducted by the National Center for Health Statistics at CDC designed to assess the health and nutritional status of adults and children in the U.S, and combines interviews and physical examinations. NHANES stopped collecting vision and eye health data in 2008. Approximate sample size is 5,000 persons per year. NHANES data for VEHSS includes questions and examinations related to Visual Function, Vision Exam Measures, Eye Health Conditions, Service Utilization, and Examination Measures. Data were suppressed for cell sizes less than 30 persons, or where the relative standard error more than 30% of the mean. Detailed information on VEHSS NHANES analyses can be found on the VEHSS NHANES webpage (https://www.cdc.gov/visionhealth/vehss/data/national-surveys/national-health-and-nutrition-examination-survey.html). Additional information about NHANES can be found on the NHANES website (https://www.cdc.gov/nchs/nhanes/index.htm). The VEHSS NHANES dataset was last updated in June 2018.

Dataset
VEHSS Composite Prevalence Estimates
2017, 2019. This dataset contains estimates of the prevalence of vision loss and eye disorders generated using a Bayesian meta-analytic modeling approach that combines information from multiple, disparate data sources to produce comprehensive predictions of prevalence by age, race, gender, and geography at the national, state and county levels. These composite prevalence estimates are the primary surveillance measures developed by the Centers for Disease Control and Prevention’s Vision & Eye Health Surveillance System (VEHSS).

The vision loss prevalence estimates represent best-corrected visual acuity in the better-seeing eye. 'Any vision loss' represents any impairment or blindness of 20/40 or worse; 'US-defined blindness' refers to the subset of vision loss that is 20/200 or worse; 'Visual impairment' refers to the subset with visual acuity of 20/40 to <20/200.

The age-related macular degeneration (AMD) estimates represent AMD as measured with retinal imaging examination. ‘Vision threatening AMD’ includes patients with geographic atrophy, wet-form AMD, or choroidal neovascularization in either eye. ‘Non-vision threatening AMD’ includes patients with early or intermediate dry-form AMD defined as retinal pigment epithelium abnormalities or drusen ≥125 µm in the worse-affected eye, and do not have vision threatening AMD.

Data sources include the National Health and Nutrition Examination Survey (reference values), the American Community Survey, the National Survey of Children’s Health, Medicare Fee-For-Service claims, Medicaid claims, MarketScan commercial insurance claims, the Health Resources & Service Administration’s Area Resources File, and published examination study results from the Baltimore Pediatric Eye Disease Study, the Chinese American Eye Study, the Eye Diseases Prevalence Research Group, the Los Angeles Latino Eye Study, the Multi-Ethnic Study of Atherosclerosis Cohort and other studies.

Vision & Eye Health
Filtered View
2017. This dataset contains estimates of the prevalence of visual acuity loss and visual acuity blindness in the United States in 2017. These estimates are created using a Bayesian meta-analytic modeling approach that combines information from multiple, disparate data sources to produce comprehensive predictions of prevalence by age, race, sex and geography. The vision loss prevalence estimates represent best-corrected visual acuity in the better-seeing eye. 'Any vision loss' represents any impairment or blindness of 20/40 or worse; 'US-defined blindness' refers to the subset of vision loss that is 20/200 or worse; 'Visual impairment' refers to the subset with visual acuity of 20/40 to <20/200.
Data sources include the National Health and Nutrition Examination Survey (reference values), the American Community Survey, the National Survey of Childrens Health, and published examination study results from the Baltimore Pediatric Eye Disease Study, the Chinese American Eye Study, the Eye Diseases Prevalence Research Group, the Los Angeles Latino Eye Study and the Multi-Ethnic Study of Atherosclerosis Cohort.
