Anterior Segment Optical Coherence Tomography Imaging of Conjunctival Filtering Blebs after Glaucoma Surgery
Figure 2
Functioning filtering blebs. Functioning blebs, after MMC-augmented trabeculectomy, present a diffuse (a) or a cystic shape (b) at clinical evaluation. At AS-OCT (Visante OCT) these blebs show a patent and low reflective inner cavity (asterisks) (c and d), multilobed in the cystic shape, and a thick and low reflective bleb wall. In vivo laser scanning confocal microscopy (e) shows numerous intraepithelial microcysts in a glaucomatous patient after successful MMC-augmented trabeculectomy (planar reconstruction of the superior bulbar conjunctiva 6 weeks after surgery).
