In response to Dr Zanke's letter, we would first note that he raises no objection to the substantive content of our paper. Zanke's comments seem to us to be an effort in moving the goalposts: yes, we are right that genotyping does not predict whether supplements reduce the risk of age-related macular degeneration (AMD) in general, but apparently that is not the point; genotyping predicts response with respect to only 1 type of AMD progression.
