A comprehensive assessment of visual impairment in a population of older Americans. The SEE Study. Salisbury Eye Evaluation Project.

摘要: Purpose. The Salisbury Eye Evaluation Project is a longitudinal study of risk factors for age-related eye diseases and the impact disease visual impairment on physical disability. In this article, authors report prevalence in their population explore relations among various measures function.Methods. A population-based sample 2520 residents Salisbury, Maryland, between ages 65 84 years were enrolled study. Twenty-six percent participants black. Vision tests included best-corrected Early Treatment Diabetic Retinopathy Study acuity, Pelli-Robson contrast sensitivity with without glare, Randot stereoacuity, 60 degrees Humphrey fields.Results. Visual function decreased linearly age sensitivity, field tests. Stereoacuity remained constant into mid-70s declined at an accelerating rate thereafter. Black had lower reduced worse fields, all compared to white participants; however, more sensitive glare. overall pervalence acuity blacks was 5.6% versus 3.0% whites, using traditional United States definition (worse than 20/40 better 20/200) 3.3% 1.6% World Health Organization 20/60 20/400). Acuity correlated moderately fields (Spearman rho = 0.50, 0.35, 0.34, respectively). correlation glare low (rho 0.12).Conclusions. Many aspects function, not just decline age. have do rests except sensitivity. that reported by other studies similar test procedures. Low-to-moderate correlations vision scores suggest several different dimensions are being assessed.
