Change From Baseline Endothelial Cell Hexagonality in Percentage Over All 12 Weeks for Part A
Change From Baseline in Endothelial Cell Hexagonality in Percentage Over All 12 Weeks for Part A. Specular microscopy is a noninvasive photographic technique that allows visualization and analyzation the corneal endothelium. Using computer-assisted morphometry, specular microscopes analyzes the size, shape and population of the endothelial cells. Histologically, healthy corneal cells initially have a hexagonal shape. As endothelial cells die, neighboring cells enlarge to cover the empty space once occupied by the cell. This, in turn, causes the remaining cells to lose their hexagonal shape. Assessments were performed using the flex center and full auto methods for Part A and data from the flex center method was summarized. The flex center method was used for Part B. The percent of Part B is entered as a separate outcome measure. A decrease from baseline in % cell hexagonality means worse outcome, a increase from baseline means better outcome.
