Dr. Laura Periman shares her thoughts on the role of tear osmolarity testing and her approach to the ocular surface disease patient. Dr. Periman believes that tear osmolarity testing is foundational in determining the health of the lacrimal functional unit in her dry eye patients, establishing the disease severity and tracking dry eye patient's response to treatment over time.
This study evaluated the effect of oral re-esterified omega-3 fatty acids on tear osmolarity, matrix metalloproteinase-9 (MMP-9), tear break-up time (TBUT), Ocular Surface Disease Index (OSDI),
fluorescein corneal staining, Schirmer score, meibomian gland dysfunction (MGD) stage and omega-3 index in subjects with dry eyes and confirmed MGD.
