Nothing particularly exciting here but it's interesting that people with epiphora (watery eyes) without dry eye or other disease present also seem to have lowered tear osmolarity.
Tear Film Osmolarity in Epiphora.
To examine whether patients complaining of epiphora have tears of a lower osmolarity.
Sixty-three eyes of 39 patients attending an oculoplastic clinic with a primary complaint of epiphora, had their tear osmolarity recorded.
Tear Osmolarity Measurements in Dry Eye Related to Primary Sjögren's Syndrome.
To evaluate the tear osmolarity in patients with dry eye syndrome related to primary Sjögren's Syndrome (SS).
Materials and Methods:
Twenty eyes of 10 patients with dry eye and primary SS (Group 1) and 20 eyes of 20 subjects who do not have dry eye syndrome (Group 2) were included in this cross-sectional study. In all eyes, ophthalmic examination was performed
This is the largest study of its kind that I recall seeing and involved many internationally known ocular surface disease figures. Very compelling argument for the use of tear osmolarity testing in diagnosing dry eye.
Tear Osmolarity in the Diagnosis and Management of Dry Eye Disease.
PURPOSE: To evaluate the use of tear osmolarity in the diagnosis of dry eye disease.
DESIGN: A prospective, observational case series to determine the clinical usefulness
