Vision In Nhanes

2006年，我们使用NHANES全国调查数据来估计美国因未矫正屈光不正造成的视力损害程度（JAMA 2006;295:2158-2163）。我们随后对美国的屈光矫正费用进行了跟踪分析，意识到许多人已经进行了屈光矫正（例如眼镜或隐形眼镜），而其他人则需要新的或更好的屈光矫正（例如一副新眼镜或新的隐形眼镜处方）以使他们看得清楚。保守地说，每年矫正视力障碍的直接费用为40亿美元，其中10亿美元是为有需要的人提供第一套眼镜所需的费用。2008年，我们利用NHANES的数据调查了12岁及以上美国人屈光不正的影响。

In 2006 we used the NHANES national survey data to estimate the extent of visual impairment in the United States due to uncorrected refractive error (JAMA 2006;295:2158-2163). We subsequently followed up with an analysis of the cost of refractive correction in the United States realizing that many people already have refractive correction (e.g. eyeglasses or contacts lenses) and others need new or better refractive correction (e.g. a new pair of eyeglasses or a new contact lens prescription) to allow them to see well. Conservatively, the annual direct cost of correcting visual impairment is $4 billion per year, of which $1 billion represents the cost required to provide an initial set of glasses to those in need. In 2008 we investigated, using the NHANES data, the impact of refractive error in Americans ages 12 and older. As an adjunct to these papers, data from the National Health Interview Survey were analyzed to determine the extent of age-related eye diseases and degree of visual impairment reported by American adults. In addition, using focus group discussions, we investigated the factors which influence individuals to seek out preventive eye care services. Our findings indicate that communication between patients and their primary health care providers could facilitate improved access to eye care. NHANES retinal data (collected in 2005-2008 with the support of the Centers for Disease Control and Prevention) are also available to the public. In a 2010 analysis of NHANES data on adults over age 40 with diabetes, almost 32% of men and 26% of women, were estimated to have diabetic retinopathy. Manuscripts in press wll be published later in 2012. Additional analyses are underway.
