Power spectrum analysis of the inter-capillary distance for macular CC, posterior pole CC and equatorial CC, respectively. (A) Three selected 650 µm *650 µm regions of macular CC; (B) 2D power spectrum of macular CC in A; (C) example radially averaged power spectrum plot of macular CC. (D) Three selected 650 µm ∗ 650 µm regions of posterior pole CC (~4 mm away from fovea); (E) 2D power spectrum of macular CC in D; (F) example radially averaged power spectrum plot of posterior pole CC. (G) Three selected 650 µm ∗ 650 µm regions of equatorial CC; (H) 2D power spectrum of equatorial CC in G; (I) example radially averaged power spectrum plot of equatorial CC. Scale bar represent 200 µm.
