Abstract Objectives To determine whether more years spent in education is a causal risk factor for myopia, or whether myopia is a causal risk factor for more years in education. Design Bidirectional, two sample mendelian randomisation study. Setting Publically available genetic data from two consortiums applied to a large, independent population cohort. Genetic variants used as proxies for myopia and years of education were derived from two large genome wide association studies: 23andMe and… 

Evaluation of Shared Genetic Susceptibility to High and Low Myopia and Hyperopia.

The findings suggest that treatment interventions targeting common genetic risk variants associated with refractive error could be effective against both LM and HM.

Education and lung cancer: a Mendelian randomization study.

Low education is a causal risk factor in the development of lung cancer, and genetic predisposition towards longer education was additionally associated with less smoking, lower body mass index and a favourable blood lipid profile.

Association between birth weight and refractive error in adulthood: a Mendelian randomisation study

This study suggests lower BW within the normal range is causally associated with a more myopic refractive error, however, the impact of the causal effect was modest.

Association between birth weight and refractive error in adulthood: a Mendelian randomization study. British Journal

This study suggests lower birth weight within the normal range is causally associated with a more myopic refractive error, however, the impact of the causal effect was modest and covering approximately 95% of the population.

Effect of Education on Myopia: Evidence from the United Kingdom ROSLA 1972 Reform

Additional compulsory schooling due to the ROSLA 1972 reform was associated with a more negative refractive error, providing additional support for a causal relationship between education and myopia.

Association Between Polygenic Risk Score and Risk of Myopia

A personalized medicine approach appears to be feasible for detecting very young children aged 0 to 6 years at risk of myopia; however, beyond the age of 6 years, cycloplegic autorefraction seems to perform better.

Risk Factors for Myopia: Putting Causal Pathways into a Social Context

It is argued that there are two major environmental risk factors for school myopia, with a limited role for genetic variation and minimal interactions, and a method for comparing the impact of identified genetic risk factors with the cumulative effects of environmental exposures is proposed.

Temporal trends in frequency, type and severity of myopia and associations with key environmental risk factors in the UK: Findings from the UK Biobank Study

The differential impact of educational experience/intensity on both childhood-onset and high myopia, amplified over time, suggests a cohort effect in gene-environment interaction with potential for increasing myopia frequency if increasing childhood educational intensity is unchecked.

Geographical Variation in Likely Myopia and Environmental Risk Factors: A Multilevel Cross Classified Analysis of A UK Cohort

It is demonstrated how a multilevel modelling approach can provide a more nuanced understanding of the relationship between geography and myopia, and raise the possibility that some of the results reported may have been driven by confounding bias.

Hyperopia Is Not Causally Associated With a Major Deficit in Educational Attainment

It is suggested that the causal relationship between refractive error and educational attainment was nonlinear but found no evidence that moderate hyperopia caused a major deficit in educational attainment.



Assessing the Genetic Predisposition of Education on Myopia: A Mendelian Randomization Study

The Mendelian Randomization analysis provides new evidence for a causal role of educational attainment on refractive error and suggests that observational studies may actually underestimate the true effect of education.

How genetic is school myopia?

Phenotypic and genotypic correlation between myopia and intelligence

Novel findings indicate shared genetic factors contribute significantly to the covariance between myopia and intelligence, suggesting genetic pleiotropy.

Association Between Myopia, Ultraviolet B Radiation Exposure, Serum Vitamin D Concentrations, and Genetic Polymorphisms in Vitamin D Metabolic Pathways in a Multicountry European Study

Increased UVB exposure was associated with reduced myopia, particularly in adolescence and young adulthood, and no convincing evidence for a direct role of vitamin D in myopia risk was found.

What can mendelian randomisation tell us about modifiable behavioural and environmental exposures?

Using genetic variants as a proxy for modifiable environmental factors that are associated with disease can circumvent some of the problems of observational studies, and the inferences that can be drawn from mendelian randomisation studies depend on the different ways in which genetic variants can proxy for environmentally modifiable exposures.

Genome-wide association study identifies 74 loci associated with educational attainment

Because educational attainment is measured in large numbers of individuals, it will continue to be useful as a proxy phenotype in efforts to characterize the genetic influences of related phenotypes, including cognition and neuropsychiatric diseases.

EPIDEMIC OF PATHOLOGIC MYOPIA: What Can Laboratory Studies and Epidemiology Tell Us?

Systematic review shows that there is an epidemic of myopia and high myopia in young adults in East and Southeast Asia, with similar but smaller trends in other parts of the world, suggesting an impending epidemic of pathologic myopia.

'Mendelian randomization': can genetic epidemiology contribute to understanding environmental determinants of disease?

Mendelian randomization provides new opportunities to test causality and demonstrates how investment in the human genome project may contribute to understanding and preventing the adverse effects on human health of modifiable exposures.
