Hyperoside protects against light-induced decline of the retinal function. A Representative scotopic electroretinograms. B Amplitudes of a-wave and b-wave were plotted. Data were expressed as mean ± SD (n = 6 per group). *Compared to NLE, P < 0.05; **compared to NLE, P < 0.01; ^#compared to LE, P < 0.05; ^##compared to LE, P < 0.01. HYP-L the light-exposed mice treated with 12.5 mg/kg hyperoside, HYP-M the light-exposed mice treated with 50 mg/kg hyperoside, HYP-H the light-exposed mice treated with 200 mg/kg hyperoside, LE the light-exposed mice treated with vehicle, NLE the vehicle-treated mice without light exposure
