The Use of Cholesterol-lowering Medications and Age-related
Macular Degeneration
(From G McGwin, et al, Ophthalmology, Volume 112, Issue 3 (March
2005), Pages 488-494)
The purpose of this study was to evaluate the association between
cholesterol-lowering medications and age-related macular
degeneration (AMD). The Atherosclerosis Risk in Communities study is
a prospective, population-based study conducted in 4 communities
across the United States. A total of 15,792 individuals aged 45 to
65 years were enrolled between 1987 and 1989, and retinal
photographs were added to the study protocol at the 6-year follow-up
(1993–1995). Cases were subjects who were identified as having AMD
after applying a standard definition to their retinal photographs.
Controls did not have AMD.
The use of cholesterol-lowering medications at any time during the
study was determined and compared between cases and controls,
adjusting for the potentially effect of demographic, behavioral, and
medical characteristics.
In the study, a total of 871 AMD cases and 11,717 control cases who
did not have AMD were identified. Of the AMD cases, only 11% made
use of cholesterol-lowering medications, as compared with 12.3% of
controls (odds ratio 0.89). Adjusting for the confounding influence
of age, gender, and race revealed a statistically significant
relationship between AMD and use of cholesterol-lowering medications
(odds ratio 0.79). In the study, the AMD patients were found
to be significantly less likely to be using the cholesterol-lowering
medications.
The authors of the study concluded that the results of this study
add to the growing body of evidence that cholesterol-lowering
medications may reduce the risk of developing AMD. Additional
research is needed to document the mechanism responsible for this
association. It was felt that a clinical trial of the impact of
statins on AMD deserves consideration.
