Progress in the en-face optical coherence tomography applied to eye imaging

A review is presented of the research on high resolution imaging of the eye based on en-face OCT. This can provide a dual display of images with different depth resolutions, where the two images are OCT and the other confocal. Two applications are presented: (i) OCT/ICG systems where the confocal channel is tuned to the fluorescence of indocyanine green and (ii) aberration corrections in both OCT and confocal channels using closed loop adaptive optics for enhanced contrast and transversal resolution.
