      Prominent publications by Ronald E Klein

      KOL-Index: 20989

      BACKGROUND: HbA1c is the standard measure by which to monitor long-term (2-3 months) glucose control in people with diabetes and is now used for diagnosis of diabetes. Fructosamine and glycated albumin are markers of short-term (2-4 weeks) glycaemic control that might add complementary prognostic information to HbA1c. Our aim was to clarify the performance of fructosamine and glycated albumin measurements for identifying people at risk of incident diabetes or diabetic ...

      CONTEXT: The prevalence of diabetes in the United States has increased. People with diabetes are at risk for diabetic retinopathy. No recent national population-based estimate of the prevalence and severity of diabetic retinopathy exists.

      OBJECTIVES: To describe the prevalence and risk factors of diabetic retinopathy among US adults with diabetes aged 40 years and older.

      DESIGN, SETTING, AND PARTICIPANTS: Analysis of a cross-sectional, nationally representative sample of the National ...

      OBJECTIVE: To examine the 14-year incidence and progression of diabetic retinopathy and macular edema and its relation to various risk factors.

      DESIGN: Population-based incidence study.

      SETTING: The study was conducted in an 11-county area in southern Wisconsin.

      PARTICIPANTS: Six hundred thirty-four insulin-taking persons with diabetes diagnosed before age 30 years participated in baseline, 4-year, 10-year, and 14-year follow-up examinations.

      MAIN OUTCOME MEASURES: The 14-year ...

      OBJECTIVE: Narrowed retinal arterioles may independently predict cardiovascular disease. We describe a computer-assisted method to measure retinal vessel diameters from digitized fundus photographs in a large population, and examine the correlation of retinal vessel diameters between eyes and whether refractive errors affect these measurements.

      DESIGN AND POPULATION: Population-based, cross-sectional study in Beaver Dam, Wisconsin (n = 4926; age, 43-84 years).

      METHODS: Retinal ...

      OBJECTIVE: To investigate the relationship of various retinal lesions to systemic hypertension in the population-based Beaver Dam Eye Study.

      DESIGN: In this cross-sectional population-based study, blood pressure was measured using standardized protocols. Using standardized protocols, stereoscopic color fundus photographs were graded in a masked fashion to determine the presence of retinopathy (defined as retinal microaneurysms only, blot hemorrhages only, hemorrhages and/or ...

      BACKGROUND: Results of previous studies suggest that renin-angiotensin system blockers might reduce the burden of diabetic retinopathy. We therefore designed the DIabetic REtinopathy Candesartan Trials (DIRECT) Programme to assess whether candesartan could reduce the incidence and progression of retinopathy in type 1 diabetes.

      METHODS: Two randomised, double-blind, parallel-design, placebo-controlled trials were done in 309 centres worldwide. Participants with normotensive, ...

      PURPOSE: To describe the association of demographic, behavioral, medical, and nonretinal ocular factors with the incidence of neovascular age-related macular degeneration (AMD) and central geographic atrophy (CGA) in the Age-Related Eye Disease Study (AREDS), a randomized trial of antioxidants and zinc supplementation prophylaxis for development of advanced AMD.

      DESIGN: Clinic-based prospective cohort study.

      PARTICIPANTS: Of individuals with early or intermediate AMD at baseline with a ...

      OBJECTIVE: To determine the age- and gender-specific prevalence and risk indicators of visual impairment and blindness in urban Latinos 40 years and older.

      DESIGN: Population-based cross-sectional study.

      PARTICIPANTS: Six thousand three hundred fifty-seven Latinos 40 years and older from 6 census tracts in Los Angeles, California.

      METHODS: Of the 6357 study participants, 6122 underwent a complete ophthalmologic examination at the clinical center, including measurement of best-corrected ...

      PURPOSE: To examine the association of performance-based measures of visual functioning with the occurrence of falls, fractures, physical outcomes, and limitations in an older population.

      DESIGN: A population-based study of Beaver Dam, Wisconsin, of persons who were 43 to 86 years of age was performed from 1988 through 1990 (n = 4926), 1993 through 1995 (n = 3722), and 1998 through 2000 (n = 2962).

      PURPOSE: To describe the change in visual acuity in a 10-year period.

      DESIGN: Population-based cohort study.

      PARTICIPANTS: Included 3684 persons 43 to 86 years of age at the time of a baseline examination in 1988 to 1990, living in Beaver Dam, Wisconsin, at a follow-up examination in 1993 to 1995 and/or 1998 to 2000.

      METHODS: Best-corrected visual acuity was measured, after refraction, with logarithm of the minimum angle of resolution charts using a modification of the Early Treatment ...

      PURPOSE: To describe racial variations in the prevalence of refractive errors among adult white, Chinese, Hispanic, and black subjects in the United States.

      DESIGN: Cross-sectional data from a prospective cohort study-the Multi-Ethnic Study of Atherosclerosis (MESA).

      METHODS: A total of 6000 adults aged 45 to 84 years living in the United States participated in the study. Refractive error was assessed, without cycloplegia, in both eyes of all participants using an autorefractor. After ...

      DESIGN: Population-based cohort study.

      PARTICIPANTS: The study included 4926 persons, 43 to 86 years of age at the time of a baseline examination from 1988 through 1990, living in Beaver Dam, Wisconsin, of whom 3684 participated in a 5-year follow-up examination and 2764 participated in a 10-year ...
