Dry Eye

Dry eye is a common condition, affecting approximately 10% of the adult population. Artificial tears are often effective in relieving symptoms in mild and moderate dry eye by replenishing deficient tear volume. Sodium hyaluronate has been proposed as a component in artificial tears, due to its viscoelastic rheology. Its exceptional water retention properties result in enhanced hydration of the corneal surface. Moreover, applications of ophthalmic formulations containing HA reduce tear elimination and enhance precorneal tear film stability, which is a useful property against dry eye syndrome.

HA plays a major role in maintaining the health of ocular tissues such as the cornea, the retina, and the vitreous fluid that fills the inside of the eye. It is been said that after the 5th decade of life, the eye has lost 50% of its ability to product the needed HA. HA supplementation can maintain proper eye health.

Health of Ocular Tissues

HA plays an important role in several aspects of the wound healing process. Topical application of hyaluronic acid to wounds in rats leads to enhanced epithelial migration and differentiation and accelerates wound healing with reduced tissue fibrosis.Additionally, the action of HA in water homeostasis could favor tissue hydration, which has a positive effect on healing.2 King et al. found that artificial enrichment of the wound tissue with HA improved the microcirculatory perfusion of repairing tissue in the hamster cheek pouch, reduced wound-induced extravasation, and accelerated wound closure. Findings provide evidence that HA has a regulatory influence in scarless tissue repair.Considering the various cell regulatory functions designated to HA, it is feasible to suggest that the reduced content of HA in the papillary dermis could predispose for the ulcerative process.
