AimsTo determine the prevalence of myopic maculopathy in the general population in Germany and to analyse potential associations with ocular and systemic factors.DesignThe Gutenberg Health Study is a population-based study, including 15 010 participants aged 35–74 years.MethodsMyopic maculopathy was graded in phakic eyes with spherical equivalent ≤−6 D by assessing fundus photographs according to a recent international photographic classification system (META-PM). 801 eyes of 519 participants (mean age 51.0±0.77 years) met the conditions and had gradable fundus photographs. Age-specific prevalence estimates were computed. Multivariable logistic regression analysis was used to assess associated factors with myopic maculopathy.ResultsMyopic maculopathy was present in 10.3% (95% CI 7.9 to 13.3) study participants. The prevalence was 8.6% (95% CI 6.1% to 11.9%) in the 397 right eyes and 8.7% (95% CI 6.2% to 12.0%) in the 404 left eyes. The most common type of pathology was diffuse atrophy (8.1%), followed by patchy atrophy (1.3%) and macular atrophy (0.5%); plus lesions were present in 3% (right eyes). Age (OR 1.07 per year, 95% CI 1.03 to 1.11, p<0.001), higher myopic refractive error (p<0.001), and male gender (p=0.02) were associated with myopic maculopathy, while cardiovascular risk factors and socioeconomic factors were not.ConclusionsThe prevalence of myopic maculopathy in the German population was 0.5%, and 10% in high myopic participants, aged 35–74 years. These population-based data are the first in Europe. Myopic maculopathy was related to severity of myopic refractive error and age.

Myopia is already a ubiquitous phenomenon in some parts of the world. One out of ten persons will be at a relevant risk of becoming blind as a result of myopia in the future. Preventive measures have not shown sweeping success.

PurposeMyopia is increasing worldwide and possibly linked to education. In this study, we analyse the association of myopia and education in the U.S. and investigate its age-dependency.MethodsWe conducted a secondary data analysis using the public use files from the cross-sectional study National Health and Nutrition Examination Survey of the period from 1999 to 2008. 19,756 participants aged 20 to 85 years were included with data on education and ophthalmic parameters (distance visual acuity, objective refraction and keratometry). Spherical equivalent, astigmatism, corneal power and corneal astigmatism were evaluated for an association with education using linear regression analysis with adjustment of potential confounders.ResultsAnalysis revealed an association between spherical equivalent and educational level in the univariate analysis (P < .001), and in the adjusted model (P < .001). Subjects who attend school to less than 9th grade had a mean spherical equivalent of 0.34 D, subjects with 9-11th grade -0.14 D, subjects that finished high school -0.33 D, subjects with partial college education -0.70 D, subjects that graduated from college or a higher formal education -1.22 D. Subjects that graduated from college or above were -1.47 D more myopic compared to subjects that completed less than 9th grade school in the adjusted analyses. Astigmatism and corneal curvature was not associated with education.ConclusionsMyopia is associated with higher education in the U.S. Our analysis shows that corneal curvature does not contribute to this association, therefore axial elongation or lens power are likely to contribute to myopia.
