Table 2.

Comparison of best corrected visual acuity (BCVA) and intraocular pressure (IOP) in retinitis pigmentosa (RP) patients before and after hydrogen-rich water (HRW) drinking (‾x ±S.E.M.，n = 24).

Before HRW After HRW t P
BCVA 0.33 ± 0.26 0.34 ± 0.25 -2.954 0.007
IOP/mmHg 14.04 ± 2.12 13.71 ± 1.92 1.115 0.276

Note: BCVA: best corrected visual acuity; IOP: intraocular pressure; HRW: hydrogen-rich water; RP: retinitis pigmentosa; Before HRW: before the HRW drinking; After HRW: after the HRW drinking.
