Objective Evaluation of Functionality of Filtering Bleb Based on Polarization-Sensitive Optical Coherence Tomography

Abstract

The fibrosis score showed a high ability to discriminate nonfunctional from functional blebs. Polarization-sensitive OCT is a noninvasive technique that provides not only the fibrosis score but also standard structural tomography. It can be a comprehensive tool for longitudinal evaluation after filtration surgery for glaucoma.
