Trabeculectomy sample from the right eye. A: Light micrograph. B and C: Transmission electron microscopy. A: The uveal trabecular meshwork is well differentiated. The intertrabecular spaces are open (b). Well-preserved endothelial cells (E) alternate with necrotic cells (N). B: Two uveal trabecular beams lined with well-preserved endothelial cells (E) and one necrotic cell (N). The trabecular beams are filled with abundant fibrillary collagen (C) and elastic-like fibers (e). C: High magnification of an uveal trabecular beam containing a large amount of disorganized coalescent fibrillary collagen. Cross-sectioned collagen fibers (TC) alternate with fibers sectioned longitudinally (LC). Scarce electron-lucent ground substance (G) between collagen fibers and elastic-like fibers (e) is visible. Debris of endothelial necrotic cells (N).
