Evaluation of Functional Filtering Bleb Using Optical Coherence Tomography Angiography

This study investigated whether filtering blebs can be evaluated using optical coherence tomography angiography (OCT-A) and compared vascularity parameters with conventional bleb grading systems.A total of 92 patients with glaucoma, who underwent mitomycin C-augmented trabeculectomy, were enrolled in this study, and 92 eyes were assessed in total. The participants underwent OCT-A in external mode and anterior segment photography for bleb...
