TL;DR
Hydrogen-rich saline may protect the retina from damage caused by temporary loss and restoration of blood supply by reducing DNA damage and cell death.
Key Finding
Hydrogen-rich saline reduced retinal cell death and DNA damage in rats with ischemia-reperfusion injury by inhibiting overactivation of PARP-1, a protein involved in programmed cell death.
Summary
Researchers tested whether hydrogen-rich saline could protect rat eyes from damage caused by temporarily cutting off blood flow and then restoring it (a condition called ischemia-reperfusion injury). They found that hydrogen-rich saline reduced cell death and damage in the retina by decreasing oxidative stress (harmful chemical reactions) in DNA and blocking overactivation of a protein called PARP-1 that triggers cell death.
Practical Takeaway
This is an early-stage animal study suggesting hydrogen-rich saline may have protective effects against certain types of eye damage from blood flow disruption. However, this was conducted only in rats, and human studies would be needed to determine if these findings apply to people. The study does not provide evidence that hydrogen water would have similar effects.
Abstract (excerpt)
Overactivation of poly (ADP-ribose) polymerase 1 (PARP-1), as a result of sustained DNA oxidation in ischemia‑reperfusion injury, triggers programmed cell necrosis and apoptosis. The present study was conducted to demonstrate whether hydrogen‑rich saline (HRS) has a neuroprotective effect…
