Not necessarily. Emotional tears are like reflex tears in terms of the different composition, aren't they? You certainly can have little to no basal tear production at all, but still have reflex tears. I was just speaking with a doctor on Friday about a case like that. I think you can find this out by careful performance of both anaesthetized and unanaesthetized Schirmer. The patient in question had a score of 0 on the anaesthetized Schirmer and a low score (but not zero) on the unanaesthetized one.
