Association of lipid-lowering drugs, anti-diabetic drugs, non-steroidal anti-inflammatory drugs, and levodopa with age-related macular degeneration i…

Purpose : Changes in lipid metabolism, chronic inflammation and increased oxidative stress have been discussed as patho-etiogenetic drivers in age-related macular degeneration (AMD). Systemic medication, such as lipid-lowering drugs (LLD) and anti-diabetic drugs, affect these pathways and may therefore also play a role in AMD pathogenesis. We aimed to investigate associations of commonly used systemic drugs with AMD prevalence in the European population.Methods : We included 38,694 adults from 14 population-based studies from the European Eye Epidemiology (E3) consortium. We performed multivariable logistic regression modelling to examine medication use association with prevalence of AMD as…
Prevalence of Age-Related Macular Degeneration in Europe
2017
Manuscript no. 2016-1147 Supplemental material is available at www.aaojournal.org/; International audience; [u]Purpose:[/u] Age-related macular degeneration (AMD) is a frequent, complex disorder in elderly of European ancestry. Risk profiles and treatment options have changed considerably over the years, which may have affected disease prevalence and outcome. We determined the prevalence of early and late AMD in Europe from 1990 to 2013 using the European Eye Epidemiology (E3) consortium, and made projections for the future. [u]Design:[/u] Meta-analysis of prevalence data. [u]Participants:[/u] A total of 42 080 individuals 40 years of age and older participating in 14 population-based cohor…
Genome-wide association meta-analysis of corneal curvature identifies novel loci and shared genetic influences across axial length and refractive err…
2020
Corneal curvature, a highly heritable trait, is a key clinical endophenotype for myopia - a major cause of visual impairment and blindness in the world. Here we present a trans-ethnic meta-analysis of corneal curvature GWAS in 44,042 individuals of Caucasian and Asian with replication in 88,218 UK Biobank data. We identified 47 loci (of which 26 are novel), with population-specific signals as well as shared signals across ethnicities. Some identified variants showed precise scaling in corneal curvature and eye elongation (i.e. axial length) to maintain eyes in emmetropia (i.e. HDAC11/FBLN2 rs2630445, RBP3 rs11204213); others exhibited association with myopia with little pleiotropic effects …
Rare variant analyses across multiethnic cohorts identify novel genes for refractive error
2023
Refractive error, measured here as mean spherical equivalent (SER), is a complex eye condition caused by both genetic and environmental factors. Individuals with strong positive or negative values of SER require spectacles or other approaches for vision correction. Common genetic risk factors have been identified by genome-wide association studies (GWAS), but a great part of the refractive error heritability is still missing. Some of this heritability may be explained by rare variants (minor allele frequency [MAF] ≤ 0.01.). We performed multiple gene-based association tests of mean Spherical Equivalent with rare variants in exome array data from the Consortium for Refractive Error and Myopi…
