In vivo human retinal imaging by (c, d) FF-OCT compared with (f, g) AO retinal camera of the near periphery at 6° eccentricity. (a) The SD-OCT cross-sectional image of the imaging position with the red (RNFL) and blue (IS/OS) dashed lines indicates the FF-OCT imaging depth. (b) Fundus photography with the black box indicating the FF-OCT imaging area and the green dashed line showing the SD-OCT scanning position. In vivo FF-OCT image at 6° inferior to the fovea at the (c) RNFL and (d) IS/OS photoreceptor layer without AO. (e) The 2D power spectra of (d) show the Yellot’s ring, the radius of which is related to the cone photoreceptor spacing. The AO retinal camera image around the (f) RNFL and (g) IS/OS photoreceptor layer at the same retinal location, and (h) the 2D power spectra of (g). Scale bar: 100 μm.
