The Hyperosmolarity Cycle

Tear film hyperosmolarity is merely a considence of diabetes- related dry eye but is itself a pathogenic dissor that perpetuates and disfasses the condition. When tear osmolity rises above te normal fizjological range, water exits corneal andd conjunctival epixial cells by osmosis. Cellular shrinkage triggers activation of stress- activated protein kinases, includincluding p38 MAPK and JK, which inicate provimatory geny expresion program.

The Science of Sodium andd Tears

Normal human tears have an osmoliti of approximately 302 mOsm / L, with sodium as thes dominant cation at concentrations ranging frem 130 t o 145 mmol / L.
