Narrative review reveals the pathological role of tear hyperosmolarity in dry eye disease, suggesting osmoprotectants provide protective ocular cellular defense.

Key Points

To examine the pathogenic mechanisms of tear hyperosmolarity in dry eye disease and evaluate the clinical efficacy of osmoprotectant therapies.
Proceedings and expert consensus review conducted by the OCEAN Group examining biological mechanisms and clinical management strategies in dry eye disease.
Synthesized evidence on conventional hypotonic tear substitutes and emerging small organic osmoprotectant formulations.
Tear hyperosmolarity triggers corneal and conjunctival cell apoptosis, loss of mucin-producing goblet cells, and inflammatory cascades that perpetuate tear film instability.
Conventional hypotonic tear substitutes provide transient osmolarity reduction due to short ocular retention times.
Osmoprotectants including erythritol, taurine, trehalose, and L-carnitine restore cellular volume and stabilize proteins, directly shielding ocular surface cells to break the vicious disease cycle.
