Paper Abstract
Polarization-sensitive optical coherence tomography (PS-OCT) has been developed to measure the birefringent
properties of the human eye. In the retina, retinal nerve fiber layer and retinal pigment epitherial layer have the
characteristic birefringent properties.1.2 In addition to such normal tissue, abnormal fibrous tissue of the retina can be
detected by PS-OCT.3 In the anterior segment, the cornea is a birefringent tissue due to the multi-layered fibril
structure.4 The sclera and tendon also have the birefringence and the contrast of these structures can be enhanced by
PS-OCT.5 These studies have been used time-domain or spectral-domain PS-OCT. Recently, swept-source OCT
(SS-OCT) has been applied for anterior eye segment imaging.6 At the 1.3 um wavelength, SS-OCT is more promising
than spectral-domain OCT, because the available camera for the spectrometer is limited. Three-dimensional imaging
of the anterior segment is possible owing to the high penetration, high acquisition speed and high sensitivity. We have
developed a new system of SS-OCT with polarization sensitivity. In this study, we measure the birefringent properties
of anterior eye segment by polarization-sensitive spectral-domain OCT (PS-SD-OCT) at 840 nm and polarizationsensitive
swept-source OCT (PS-SS-OCT) at 1.3 um, and evaluated the possibilities for clinical application.
