Analyses of Existing Framingham Data
Continued Analyses of Epidemiologic Risk Factors Using Existing Framingham Eye and Heart Study Data
Since 1948, the Framingham Study has examined a group of men and women every two years for the primary purpose of studying the incidence and prevalence of cardiovascular disease and its risk factors. In 1971 the Framingham Study began a study of the offspring of the original group, including data collection on blood pressure, cigarette smoking, weight, and other factors that are of interest to studies of eye disease. Researchers gave eye exams to some of the original group and to the offspring group. Data from these eye exams have been used to examine risk factors for cataracts, diabetic retinopathy, myopia, and glaucoma.
The purpose of this study is to use the previously collected data for continued research on eye-related disorders. No new eye examinations will be conducted.
