Abstract: Hydrogen has the properties of antioxidant, antiapoptotic, antiinflammatory, antiallergic. The antioxidant property of hydrogen is through selectively eliminating hydroxyl radicals. Animal experiment studies have confirmed that hydrogen has the neuroprotective effects on retinal ischemiareperfusion injury, and the protective effects of hydrogen on hyperoxiainduced retinopathy, blue lightinduced retinal damage and diabetic retinopathy. The inhibited effect on the corneal neovascularization  induced by alkaliburn  in rats has been also proven. (Int Rev Ophthalmol, 2013, 37: 424-428)
