title: 3-hydroxy-3-methylglutaryl coenzyme a reductase inhibitors and the presence of age-related macular degeneration in the Cardiovascular Health Study.
abstract: OBJECTIVE
  To evaluate both the use of cholesterol-lowering medications as a group and the use of statins specifically with regard to the risk of age-related macular degeneration (AMD).
  
  
  METHODS
  A case-control study was conducted using data from the Cardiovascular Health Study, a population-based prospective study of adults enrolled from 4 communities in the United States in 1989 and 1990. Individuals with AMD (cases) and those without AMD (controls) were compared with regard to their use of cholesterol-lowering medications and statins.
  
  
  RESULTS
  Nearly equal proportions of cases and controls used cholesterol-lowering medications, both before adjustment (odds ratio, 0.92; 95% confidence interval, 0.70-1.21) and after adjustment for selected confounding variables (age, sex, and race) (odds ratio, 1.35; 95% confidence interval, 0.98-1.87). Statin use was also found to be similar among cases and controls (odds ratio, 0.98; 95% confidence interval, 0.73-1.30). After controlling for the aforementioned 3 confounders (odds ratio, 1.40; 95% confidence interval, 0.99-1.98), we noted a modest trend for statin users to have an increased risk of AMD.
  
  
  CONCLUSIONS
  The results suggest that no association exists between having used cholesterol-lowering medications and AMD. However, there was a suggestion that statin use might increase the risk of AMD.
