Abstract

An application of swept-source polarization sensitive optical coherence tomography (PS-OCT) to anterior eye is presented. The image properties of anterior eye segments in PS-OCT images are discussed. The ability of PS-OCT to visualize trabecular meshwork is evaluated. For this evaluation, 25 normal subjects were involved. The visibility of trabecular meshwork in PS-OCT images of the subjects were scored by 2 graders. The grading score were then statistically analyzed. This analysis shows a statistically significant improvement of the visibility of trabecular meshwork in PS-OCT images against conventional intensity OCT images. A birefringent artifact appeared in anterior eye segment OCT image is also discussed.
