  As the lateral resolution of FFOCT with spatially incoherent illumination has
been shown to be insensitive to aberrations, we demonstrate high resolution en
face full-field OCT (FFOCT) retinal imaging without wavefront correction in the
human eye in vivo for the first time. A combination of FFOCT with
spectral-domain OCT (SDOCT) is applied for real-time matching of the optical
path lengths (OPL) of FFOCT. Through the real-time cross-sectional SDOCT
images, the OPL of the FFOCT reference arm is matched with different retinal
layers in the FFOCT sample arm. Thus, diffraction limited FFOCT images of
multiple retinal layers are acquired at both the near periphery and the fovea.
The en face FFOCT retinal images reveal information about various structures
such as the nerve fiber orientation, the blood vessel distribution, and the
photoreceptor mosaic.
