In a single-arm interventional study, 13 patients with primary retinitis pigmentosa drank hydrogen-rich water for four weeks. The central result was a statistically significant improvement in best corrected visual acuity, with some improvements in electroretinogram parameters, but no significant changes in retinal or choroidal thickness.
This non-randomized interventional study investigated the effect of drinking hydrogen-rich water (HRW) in 13 patients (24 eyes) with primary retinitis pigmentosa (RP). Patients consumed 400–500 ml of HRW twice daily for four weeks. Outcome measures, including best corrected visual acuity (BCVA), intraocular pressure, retinal/choroidal thickness, and visual electrophysiology (ERG and VEP), were assessed before and after the intervention. Certain ERG parameters, such as amplitudes and peak times in both dark- and light-adapted responses, also showed significant improvements. However, no significant differences were observed in intraocular pressure, retinal thickness, or choroidal thickness. The study notes limitations, including a small sample size, lack of a control group, short intervention duration, and potential unmeasured influences from diet or water intake during the study period. The findings suggest a potential slight benefit on visual function but do not support a morphological effect on the retina or choroid.
