Figure 4. Retinal spectra of the same age women in different degrees of dementia among dementia group (n = 24), MCI group (n = 18), and Normal group (n = 16). (A–E) show the different region in the retina (A) F, (B) I1, (C) I2, (D) S1, and (E) S2. Specifically, positions F, I1, I2 and S2 show the difference in the long wavelength region (>550 nm). Data shown as mean normalized spectrum.
