Abstract

Glaucoma is a chronic optic neuropathy that severely damages the optic nerve head. Accurate information about the nerve fiber bundle (RNFB) trajectories in the retinal nerve fiber layer (RNFL) can improve earlier diagnosis and monitoring. Using polarization-sensitive (PS) OCT volume data we propose a fully automatic method of tracing RNFB trajectories. Preliminary analysis of automatically constructed RNFB traces shows a higher concordance to manually performed traces in comparison to a purely mathematical model. On repeated measurements of the same eye they also provide a higher reproducibility than results delivered by different graders.
