LOINC display name : Osmolarity (Tear) [Osmolarity];
LOINC long common name : Osmolarity in Tear;
LOINC short name : Osmolarity Tear;
LOINC description : The osmolarity or concentration of the ocular tear fluid will indicate if the patient
is being affected by dry eye disease, which would result in a hyperosmolar tear fluid
caused by either the reduction of tear fluid production by the lacrimal gland or the
abnormal increase in evaporation of the tear fluid on the surface of the eye. A hyperosmolar
tear film is toxic to the ocular surface resulting in cell damage, apoptosis, inflammation
and an unstable tear film contributing to abnormal visual acuity. This term was created
for, but is not limited in use to, the submitter's TearLab Osmolarity System.;
