[Research progress of hydrogen-rich saline for eye diseases].

Abstract

Molecular hydrogen has attracted considerable attention as an antioxidant agent with a favorable safety profile, as it does not interfere with essential metabolic redox processes or disrupt reactive oxygen species involved in cellular signaling. Evidence from biological and medical research indicates beneficial outcomes across multiple organ systems, including the nervous, digestive, and respiratory systems, as well as the heart and kidneys. However, investigations into its effects on ocular conditions remain sparse. This review consolidates findings from domestic and international literature to outline the current state of research on hydrogen-rich water in the context of eye diseases, highlighting areas where evidence is emerging and where further study is warranted.

Mechanism

Hydrogen acts as a selective antioxidant, neutralizing excess reactive oxygen species without disrupting those required for normal cellular signaling, thereby potentially protecting ocular tissues from oxidative damage.
