Fig. 3. (A) Comparison of the number of dead cells from live/dead cell assay and TUNEL(+) cells in 5 consecutive microscopic fields between the Cosopt and Cosopt-S groups (×400). (B) TUNEL stain of rabbit cornea 24 hours after Cosopt injection. Several TUNEL(+) cells are present in the endothelial cell layer. (C) TUNEL stain of rabbit cornea 24 hours after Cosopt-S injection. TUNEL-positive cells are absent (×400).
