Methods for a population-based study of the prevalence of and risk factors for age-related maculopathy and macular degeneration in elderly European populations: the EUREYE study

Abstract

Purpose: The aims of the EUREYE study are to evaluate the prevalence of age-related maculopathy (ARM), including macular degeneration (AMD), in elderly European populations, to investigate risk factors for ARM and AMD, especially solar radiation and diet, and to measure the impact of these conditions on vision-related quality of life.

Methods: A population-based cross-sectional study with retrospective and current exposure measurements. Risk factor assessment is via questionnaires (for lifestyle factors such as smoking and alcohol, dietary risk factors, outdoor exposure) and blood analysis. Participants are people aged 65 and over. The study is carried out in 7 centres with locations spanning north to south Europe. The main outcome measure is grading of fundus photographs (for stage and type of ARM, using the International ARM Epidemiological Study Group grading system).
