In Reply We completely agree with Dr Keller about the importance of having aspirin intake dose information and his comment about what we reported was “time dose” or use duration-dose pattern but not quantitative dose of aspirin intake. If an intake dose-response pattern were found with the aspirin dose data, this would strengthen the evidence supporting an association between aspirin use and age-related macular degeneration (AMD) and inform clinical practice. However, we do not have precise dosage data collected from our study sample.
