Figure 1: (a) Normal trabecular meshwork × 200; 78-year-old male. There are well-defined thin, rounded uveal beams enclosing many large spaces, running perpendicular to the peripheral cornea, (C). Flatter trabeculae with smaller spaces are seen beneath. (b) Acute PACG eye × 200; 57-year-old female, highest IOP recorded 56 mm Hg. The intracameral face of the trabecular meshwork appeared to have an irregular surface, with no appreciable landmarks. No trabecular beams are visible and only a few small spaces are seen. The peripheral corneal endothelium is also swollen above, (C). (c) Chronic PACG eye × 200; 65-year-old female, highest baseline IOP 40 mm Hg. From above downwards, peripheral corneal guttae, (C), the smooth zone of the trabecular meshwork, (S), and the posterior uveal trabeculae are visible. There are no anterior uveal trabeculae or spaces visible. There is an irregular, fan-shaped configuration of trabeculae converging at the end of the corneal endothelium, (black arrow). (d) POAG eye × 200; 67-year-old male, highest baseline IOP 30 mm Hg. From above downwards, some corneal guttae (C), the smooth zone of the trabecular meshwork (S), and the uveal meshwork are visible. The uveal beams are thinner anteriorly, and become significantly broader posteriorly. The surface shows particulate debris and RBCs
