Phase retardation of retinal nerve fiber layer (RNFL) is measured by polarization-sensitive spectral domain optical coherence tomography (PS-SD-OCT) and scanning laser polarimetry (SLP). In PS-SD-OCT, birefringence of the optical fiber and the cornea is compensated by Jones matrix based analysis. Three-dimensional phase retardation map around the optic nerve head and era face phase retardation map of the RNFL are shown. It is shown that the phase retardation curves around the optic nerve head measured by PS-SD-OCT and SLP have similar values. PS-SD-OCT can measure the cumulative phase retardation of RNFL as well as SLP and has a possibility to evaluate RNFL for glaucomatous eyes.
