Increased tear osmolarity (salt concentration) causes eye surface inflammation

New research confirms elevated tear osmolarity (increased salt in the tears) causes dry-eye surface disease. In an article published this month in Eye & Contact Lens Luo, Li, Corrales and Pflugfelder demonstrate that ocular surface inflammation in dry eye is caused by elevated tear film osmolarity.

Some had believed that there was a direct inflammatory attack on the eye surface independent of the decrease in tear production or increase in tear film evaporation that is characteristic of dry-eye disease. We now know this is untrue.

I had the opportunity to write an editorial on this paper that highlights the important treatment ramifications of this research. Click HERE to read this editorial.
