Figure 2: (a) Normal trabecular meshwork, × 500; 72-year-old male. Two to three layers of thinner, more cylindrical, superficial uveal trabeculae are seen, (dashed arrow), overlying flatter corneoscleral trabeculae. The trabeculae are discrete with smooth surfaces, with large, clear spaces between them. A few melanin granules can be seen. (b) Acute PACG eye × 500; 60-year-old female, highest IOP of 52 mm Hg. The trabecular endothelial cells are grossly thickened, irregular and crenated. Some spaces can be seen between the swollen cells, (thin arrow). There are numerous leucocytes on and between the cells (thick arrow). (c) Chronic PACG eye × 500; 62-year-old male, baseline IOP of 38 mm Hg. There are cylindrical trabeculae seen to the left, (dashed arrow). Posterior trabeculae to the right are flat, widened, irregularly branching, and nodular, with spaces seen between them. (d) POAG eye × 500; 45-year-old male, highest IOP 28 mm Hg. A few uveal trabeculae can be seen, (dashed arrow), with most being seen to be covered/ sheathed by a homogeneous material, (full arrows), which appears to bridge intertrabecular spaces, as well. Numerous melanin granules, together with fibrillar debris are present on the surface
