Figure 3. Functional food mix improved photopic retinal function in streptozotocin induced diabetic rats as assessed by electroretinogram. A: Photopic b-wave amplitudes of electroretinogram of rats. B: Photopic b-wave amplitude at an 8-dB flash intensity. C: Amplitude of photopic oscillatory potentials at an 8-dB flash intensity. D: Amplitude of scotopic oscillatory potentials at a 4-dB flash intensity. Data are presented as mean ± SEM, n = 7 per group. Significant differences between control (C) and diabetes (D, D+FF1, D+FF2) groups are indicated by *p ≤ 0.05. Significant differences between untreated diabetes (D) and treated diabetes (D+FF1, D+FF2) groups are indicated by #p ≤ 0.05. C, control; D, diabetes (untreated); D+FF1, diabetes treated with FF1; D+FF2, diabetes treated with FF2 group.
