Effect of H-1152 on human trabecular meshwork cell morphology. Cells were treated with 20 μM of H-1152 and photographed at 0.5, 1, 3, 6, and 24 h (Fig. 2). For each time point, the same field of cells was located and photographed, and no obvious cell loss was noted. One cell (the same cell) is indicated by an arrow at each time point. Data from 2, 4, and 5 h of treatment are not shown. Bar = 80 μm.
