Abstract
Objective/purpose
To evaluate the association of statin use with progression of age-related macular degeneration (AMD).
Design
Preplanned, prospective cohort study within a controlled clinical trial of oral supplementation for age-related eye diseases.
Subjects
Age-Related Eye Disease Study 2 participants, aged 50 to 85 years.
Methods
Factors, including age, gender, smoking status, aspirin use, and history of diabetes, hypertension, heart disease, angina, and stroke, all known to be associated with statin use, were included in a logistic regression model to estimate propensity scores for each participant. Age-adjusted proportional hazards regression models, with and without propensity score matching, were performed to evaluate the association of statin use with progression to late AMD. Analyses were also performed adjusting for the competing risk of death.
Main Outcome Measures
Baseline and annual stereoscopic fundus photographs were assessed centrally by masked graders for the development of late AMD, either neovascular AMD or geographic atrophy (GA).
Results
Of the 3791 participants (2462 with bilateral large drusen and 1329 with unilateral late AMD at baseline), 1659 (43.8%) were statin users. The overall analysis, with no matching of propensity scores and no adjustment for death as a competing risk, showed that statin use was not associated with progression to late AMD (hazard ratios [HR] of 1.08, 95% confidence intervals [CI] of 0.83–1.41, P=0.56). When matched for propensity scores and adjusted for death as a competing risk, the result was not statistically significant with HR: 0.81, 95% CI: 0.55–1.20, P=0.29. Further subgroup analyses of persons with or without late AMD at baseline to the various components of late AMD (neovascular, central geographic atrophy, or any geographic atrophy) also showed no statistically significant association of statin use with progression to AMD.
Conclusions
Statin use was not statistically significantly associated with the progression to late AMD in the AREDS2 participants, and these findings are consistent with the findings in the majority of previous studies. Statins have been demonstrated to reduce the risks of cardiovascular disease, but our data do not provide evidence of a beneficial effect on slowing AMD progression.
Introduction
Age-related macular degeneration (AMD), a progressive disease that results in central vision loss, is the leading cause of blindness in persons over the age of 60 years in the United States.1 The pathogenesis of AMD is unknown. Associated risk factors include increasing age, cigarette smoking, hypertension, increased body mass index, lower educational level, presence of lens opacities, and others2–5. The use of antioxidant vitamins and minerals, known as the Age-Related Eye Disease Study (AREDS) supplement, reduces the risk of progression to late AMD, suggesting that oxidative stress may play a role in AMD.6 The association of genetic polymorphism in the complement pathway involving complement factor H and many other complement factors suggest that local or systemic inflammatory pathways may also be important in the pathogenesis of AMD.7–11 This potential inflammatory pathway is further supported by the statistically significant association of elevated serum C-Reactive Protein (CRP) with AMD in the Women’s Health Study, Rotterdam Study, and AREDS.4,7,8,12,13
Statins, or 3-hydroxy-3-methylglutaryl-coenzyme A reductase inhibitors, currently the most commonly prescribed lipid-lowering class of drugs,14 are proven to lower serum lipids and reduce cardiovascular morbidity and mortality.15 The main role of statins is to inhibit 3-hydroxy-3-methyl-glutaryl-CoA reductase in the liver, down-regulating lipid metabolism.16 However, this class of drugs has exhibited unexpected anti-inflammatory, antioxidative, and anti-angiogenic effects.17–20 Pathological studies in AMD have also demonstrated the accumulation of lipids in Bruch’s membrane similar to the atherosclerotic changes of cardiovascular disease21–23, suggesting that statins might have an effect on AMD. Previous observational studies demonstrated that statin use was associated with a protective effect on AMD24–33; however, other studies were not confirmatory.34–37 Lipid lowering with 40 mg of simvastatin in a small proof of concept study, was associated with a possible beneficial effect especially for those persons with bilateral intermediate AMD and those with genotype of the risk alleles for Complement Factor H (CFH) for progression to late AMD.38
The Age-Related Eye Disease Study 2 (AREDS2) was a prospective, multi-centered clinical trial that tested oral supplements of omega-3 fatty acids and lutein/zeaxanthin for the treatment of AMD and cataract.39 These participants were followed for a median of 5 years and the observational data from this study provided the opportunity to investigate the effect of statins on progression to late AMD.
Methods
Study population
The study design for AREDS2 is detailed in a previous report but briefly summarized here.39 Between 2006 and 2008, 4203 participants ranging from 50 to 85 years of age were enrolled at 82 retinal specialty clinics in the United States. At enrollment, participants were included if they had either bilateral large drusen or unilateral late AMD in one eye and large drusen in the fellow eye. Institutional review board approval was obtained at each clinical site, and written informed consents for the research were obtained from all study participants.
The AREDS2 participants were randomly assigned to placebo, lutein/zeaxanthin, docosahexaenoic acid (DHA) plus eicosapentaenoic acid (EPA) or the combination. At the baseline and each annual study visits, comprehensive eye exams were performed, including stereoscopic fundus photographs by certified photographers. These images were assessed by trained graders using a standardized protocol at the University of Wisconsin Fundus Photograph Reading Center. The main study outcome is the development of late AMD as graded from annual fundus photographs.
In AREDS2, late AMD was defined as having at least 2 features of neovascularization including serous detachment of the sensory retina, hemorrhage, retinal pigment epithelial detachment, fibrous tissue, or hard exudates; or geographic atrophy of an area of 360 μm or greater in diameter, involving the center of the macula; or a history of treatment for neovascular AMD. In this study we used the recently recommended and more inclusive definition of “late AMD”, which includes any definite GA in the definition, not just central GA.12
Questionnaires administered at the baseline and annual study visits were used to collect information on nutrition, medications, adverse events, and treatment compliance, among others. Telephone calls were performed twice in the first year of randomization and annually thereafter to collect information about adverse events as well as treatment for AMD and incidence of cataract surgery between the study visits.
Statistical methods
We included only participants who had no missing values to evaluate the effect of statins on eyes with intermediate AMD on the progression to late AMD. Baseline patient characteristics were compared between statin users and non-users using the t-test for continuous variables (age) and χ2 test for categorical variables including gender, race, education level, smoking status, diabetes, non-steroidal anti-inflammatory drug (NSAID) use, acetaminophen use, hypertension (defined as >140 mmHg systolic and/or >90 mmHg diastolic blood pressures), congestive heart failure, coronary heart disease, angina, history of myocardial infarction (MI), and history of stroke.
Propensity score approach can be used to reduce or eliminate the effects of confounding when using observational data (e.g., statin use) to estimate treatment effects.40 In order to reduce the effects of confounding for statin use, we used logistic regression to estimate propensity scores, which range from zero to one and indicate the probability that a participant is a statin user, based upon the risk factors listed above. Values closer to one indicate a higher likelihood of a participant using statins. After developing the propensity score for statin users and non-users, we matched statin users to non-users using the propensity scores in order to mimic characteristics of a controlled clinical trial.41 Applied in the context of statin usage in AREDS2, propensity matching approach consisted of forming match sets of statin user and non-statin users who share a similar value for the propensity score. Baseline characteristics were included in the matching model which excluded data that could not be matched.
This propensity score matching is a second method to attempt to control for the confounding from the variables in the propensity score that are both associated with statin use and with progression of AMD. The matching was done using a Greedy Matching Technique (Parsons LS. Reducing Bias in a Propensity Score Matched-Pair Sample Using Greedy Matching Techniques. Paper presented at: Proceedings of the Twenty-Sixth Annual SAS Users Group International Conference, 2001; Long Beach, CA).
Age-adjusted proportional hazards regression models were used to evaluate the effect of statin use on progression to any late AMD, including neovascular AMD and GA, in the entire cohort. Additional analyses were conducted separately for the development of neovascular AMD and GA. The competing risk of death was taken into account using the macro of Kohl and Heinze to fit a proportional sub-distribution hazards model.42,43 Hazard ratios (HRs) were calculated with 95% confidence intervals (CIs) with P < 0.05 being considered significant for all analyses.
Analyses were performed both matching and not matching statin users and non-users by the propensity scores, in addition to adjusting for death as a competing risk. Analyses were also performed separately for the two groups: participants with bilateral large drusen and participants with unilateral late AMD. No adjustments were made for multiplicity of analyses. All analyses were conducted using SAS version 9.3 (SAS Institute Inc).
Results
Of the 3791 participants included in this analysis, progression to late AMD by the end of the study occurred in 1650 (869 any geographic atrophy, 479 central geographic atrophy, and 998 neovascular AMD). Each participant could have any combination of the late forms of AMD. Associations of possible confounders with statin use are shown in Table 1. The result from proportional hazards regression model on the entire cohort, adjusting for the propensity scores, age, baseline AMD status, showed no association of statin use with the development of late AMD (hazard ratios [HR]: 1.08, 95% confidence interval [CI] of 0.83–1.41, P=0.56) (Table 2). Similar models were developed separately for the association of statin use with the components of late AMD: any GA, central GA and neovascular AMD. Statin use was not statistically significantly associated with the development of any of these outcomes, with or without accounting for the competing risk of death (Table 2).

Matching occurred with both participants in the bilateral large drusen group (n=1546), both in the unilateral AMD group (n=944), and one in the bilateral large drusen group and one in the other group (n=22). The baseline characteristics of these participants are displayed in Table 3. The previously statistically significant differences in the covariates, comparing statin users and the statin non-users, are no longer statistically significant, indicating the propensity matching has controlled for confounders. One problem with the propensity score matching is that although the age between statin users and non-users was similar as a whole, there was a large range in the age difference for individual pairs of propensity-matched participants, ranging from 0–30 years. Because older age is highly associated with an increased risk of development of AMD (P < 0.0001 for any AMD, any GA, central GA, and neovascular AMD), we adjusted the propensity score matched proportional hazards regression models for age.

Discussion
The results from the observational data from AREDS2 showed no statistically significant effect of statin use on progression to late AMD in persons at risk. The results for the endpoints of neovascular AMD or geographic atrophy were also very similar. Compared with previous studies evaluating this association, the AREDS2 had one of the largest numbers of persons with late AMD, and greater than 40% of the AREDS2 participants were statin users.
Following the initial report of the inverse association of statins with AMD by Hall et al,26 many of the subsequent reports suggested no statistically significant beneficial or harmful effect of statin use on the progression of AMD (Table 5). Some of the previous reports included large retrospective studies, but they were limited by the lack of validated methods to determine the diagnosis of late AMD because the diagnosis was based upon medical record reviews instead of the fundus photographs that were obtained in AREDS2.25,31,34,44 Another prospective study that had fundus photographs for detecting AMD lacked sufficient sample size because of small numbers of late AMD outcomes and participants taking statin.32

The Complications of AMD Prevention Trial, the Rotterdam Study, and a study pooling three different prospective studies all found no effects of statins on AMD progression.35,37,45 These prospective studies also had fundus photographs that were graded with standardized protocol. However, these studies were again limited by the lack of large numbers of either statin users or participants with late AMD. The use of statins expanded considerably after the publication of the Scandinavian Simvastatin Survival Study (1994), which demonstrated the safety and efficacy of simvastatin. Subsequently, the use of statins increased markedly, as reflected in the high proportion of AREDS2 participants taking statins two decades later.15,46
This current AREDS2 study has limitations. We lacked information on former statin use, dosages of statins, and exact duration of treatment, although our annual questionnaire results suggested that perhaps 85% of these participants were on a statin for the average 5 year follow-up in this study. While the AREDS2 participants were part of a controlled randomized clinical trial, the data used for analyses were observational and subject to confounding. In order to control for confounding variables, common in observational studies, we used propensity scores and subsequent matching, although it was difficult to match for age by the propensity score. Because the risk factors for AMD are similar to risk factors for cardiovascular disease and statin use, it is difficult to tease out the effects of confounding entirely. We also lacked the power to evaluate the potential of statin therapy to reduce the progression to early AMD as we did not have persons with no AMD in this study population. Such a study would require an extremely large number of participants.
Ideally, the best way to evaluate the effects of statins on the progression to late AMD would be a randomized controlled clinical trial. However, randomizing people to statin use is not possible, at least for those with elevated lipids, because statin use has been demonstrated to be effective in this group. Although randomly assigning persons with normal lipid levels to statins would be feasible, there are both ethical issues and concern related to compliance for persons developing cardiovascular risk factors during the study that make this problematic. For now, the totality of evidence would suggest that statins have little influence on progression to late AMD. Because of the beneficial effects of statins in reducing the risk of cardiovascular disease and mortality, persons with AMD should be encouraged to take statins when medically indicated and to be monitored regularly for progression of AMD regardless of statin use.
