Animal StudyHighlightedProtection of the Retina by Rapid Diffusion of Hydrogen: Administration of Hydrogen-Loaded Eye Drops in Retinal Ischemia–Reperfusion InjuryMHID-7978470PMID: 198340322010Investigative Ophthalmology & Visual ScienceHideaki Oharazawa, Tsutomu Igarashi, Takashi Yokota, Hiroaki Fujii, Hisaharu Suzuki, Mitsuru Machide, et al.PURPOSE. Retinal ischemia-reperfusion (I/R) injury by transient elevation of intraocular pressure (IOP) is known to induce neuronal damage through the generation of reactive oxygen species. Study results have indicated that molecular hydrogen (H2) is an efficient antioxidant gas that selectively reduces the hydroxyl radical (OH) and suppresses oxidative stress-induced injury in several organs.
