title: Ankle-brachial index and the prevalence of age-related maculopathy.
abstract: OBJECTIVE
  To examine the association of ankle-brachial blood pressure index (ABI) with prevalence of age-related maculopathy (ARM).
  
  
  METHODS
  A cross-sectional cohort study.
  
  
  METHODS
  ABI was measured in 2447 subjects aged 53 to 97 years. ARM was determined from 30-degree color stereoscopic fundus photographs.
  
  
  RESULTS
  Low ABI (< or =0.9) was present in 5.4% of subjects. Early ARM was present in 22.1% of subjects with and 18.8% without low ABI. Late ARM was present in 5.3% of subjects with and 1.7% without low ABI. This result was not statistically significant.
  
  
  CONCLUSIONS
  Low ABI does not appear to be a risk factor for ARM.
