Myopia is frequently cited as a risk factor for glaucoma, based on findings from many epidemiological studies. However, these studies are potentially subject to misclassification bias. Glaucoma is largely diagnosed based on optic disc cupping together with a visual field defect. Myopic patients may also have anomalous (or difficult to assess) optic discs together with visual field defects. This talk will examine the epidemiological link between myopia and glaucoma, and address the question whether the observed association between myopia and glaucoma is causal. Published evidence will be critically reviewed and supplemented with the findings from the EPIC‐Norfolk Eye Study (European Prospective Investigation of Cancer).
