Global burden of eye and vision disease as reflected in the Cochrane Database of Systematic Reviews.
Eye and vision disease burden should help guide ophthalmologic research prioritization. The Global Burden of Disease (GBD) Study 2010 compiled data from 1990 to 2010 on 291 diseases and injuries, 1160 disease and injury sequelae, and 67 risk factors in 187 countries. The Cochrane Database of Systematic Reviews (CDSR) is a resource for systematic reviews in health care, with peer-reviewed systematic reviews that are published by Cochrane Review Groups. ⋯ These results prompt further investigation into why certain diseases are overrepresented or underrepresented in the CDSR relative to their DALY. With regard to ophthalmologic conditions, this study encourages that certain conditions get more focus to create a better representation of what is causing the most disability and mortality within this research database. These results provide high-quality and transparent data to inform future prioritization decisions.

Randomized Controlled Trial Multicenter Study Comparative Study
Age-related cataract in men in the selenium and vitamin e cancer prevention trial eye endpoints study: a randomized clinical trial.
Observational studies suggest a role for dietary nutrients such as vitamin E and selenium in cataract prevention. However, the results of randomized clinical trials of vitamin E supplements and cataract have been disappointing and are not yet available for selenium. ⋯ These data from a large cohort of apparently healthy men indicate that long-term daily supplementation with selenium and/or vitamin E is unlikely to have a large beneficial effect on age-related cataract.
