Worldwide prevalence and risk factors for myopia

Abstract

Citation information: Pan C‐W, Ramamurthy D & Saw S‐M. Worldwide prevalence and risk factors for myopia. Ophthalmic Physiol Opt 2012, 32, 3‐16. doi: 10.1111/j.1475‐1313.2011.00884.x Background: Myopia, the most common type of refractive error, is a complex trait including both genetic and environmental factors. Numerous studies have tried to elucidate the aetiology of myopia. However, the exact aetiology of myopia is still unclear. Purpose: To summarize the worldwide patterns and trends for the prevalence of myopia and to evaluate the risk factors for myopia in population‐based studies. Recent findings: The prevalences of myopia vary across populations of different regions and ethnicities. In population‐based studies on children, the prevalence of myopia has been reported to be higher in urban areas and Chinese ethnicity. The regional and racial difference is not so obvious in adult populations aged over 40 years. More time spent on near work, less time outdoors, higher educational level and parental history of myopia have been reported to increase the risk of myopia. Conclusions: Environmental factors play a crucial role in myopia development. The effect of gene‐environment interaction on the aetiology of myopia is still controversial with inconsistent findings in different studies. A relatively hyperopic periphery can stimulate compensating eye growth in the centre. Longitudinal cohort studies or randomized clinical trials of community‐based health behaviour interventions should be conducted to further clarify the aetiology of myopia.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
