Tear osmolarity 305 mOsm/L was selected as cut-off value for dry eye, 309 mOsm/L for moderate dry eye, 318 mOsm/L for severe dry eye (Area-under-the-curve was 0.737, 0.759, and 0.711, respectively). The authors concluded that tear osmolarity can now be considered a test suitable to be performed in a clinical setting.
