Assessment of tear film osmolarity using the TearLab^™osmometer in normal dogs and dogs with keratoconjunctivitis sicca

Abstract

Canine tear osmolarity as determined by TearLab^™ osmometer was variable, required multiple readings to be informative, and differed from values reported for humans. Dogs with KCS had a lower tear osmolarity than did normal dogs, and this increased following cyclosporine therapy.
