Objective: To investigate the influence of different kinds of corneal diseases on corneal endothelial cells.
Methods: The endothelial cells of 91 corneal buttons obtained at the time of penetrating keratoplasty (PKP) were stained by 1% alizarin red and 0.25% trypan blue and observed under biomicroscope.
Results: Binuclear and polynuclear endothelial cells were found in every buttons.
Conclusion: Under special conditions, the human corneal endothelial cells possibly have stronger ability of mitosis and compensation.
