Trabeculectomy sample from the right eye. Light micrographs. A: Schlemm’s canal (SC) with an open lumen is present. The ciliary muscle (CM) is inserted posterior to the SC. B: The SC and two collector channels (CC) are observed. The intertrabecular spaces of the corneoscleral (a) trabecular meshwork (CTM) (double arrows) are less evident than those of the uveal (b) trabecular meshwork (UTM) (double arrows). C: Endothelial cells lining the SC wall (arrowhead). The arrow points to a giant vacuole. The juxtacanalicular tissue (JCT) (double arrows) is thick and composed of stellate cells (S), collagen fibers (C), and “optically empty spaces” (o). The CTM has a compact appearance although intertrabecular spaces (a) are visible. [E: trabecular endothelial cell].
