Fig 6. Case 3.

Trabeculectomy sample from the left eye. Transmission electron microscopy. A: Uveal trabecular meshwork. B: High magnification of inset in A. The endothelial cells of the trabecular beams have disappeared and the remains are necrotic (N). In some areas, the trabecular beams have an empty appearance (white arrow) while others are completely filled (arrowhead) with type VI non-fibrillary collagen (nf) intermingled with the collagen of the basal membrane (bm), as observed in B. The degraded type VI collagen detaches from the periphery of the trabecular beam (black arrow). [e: elastic-like tissue; G: ground substance].
