Purpose:
To examine the association of ankle-brachial blood pressure index (ABI) with prevalence of age-related maculopathy (ARM).
Design:
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.
