  Optical Coherence Tomography (OCT) is a non-invasive depth resolved optical
imaging modality, that enables high resolution, cross-sectional imaging in
biological tissues and materials at clinically relevant depths. Though OCT
offers high resolution imaging, the best ultra-high-resolution OCT systems are
limited to imaging structural changes with a resolution of one micron on a
single B-scan within very limited depth. Nanosensitive OCT (nsOCT) is a
recently developed technique that is capable of providing enhanced sensitivity
of OCT to structural changes. Improving the sensitivity of OCT to detect
structural changes at the nanoscale level, to a depth typical for conventional
OCT, could potentially improve the diagnostic capability of OCT in medical
applications. In this paper, we demonstrate the capability of nsOCT to detect
structural changes deep in the rat cornea following superficial corneal injury.
