Methods: For six patients who had undergone autologous rotational penetrating keratoplasty the relative annual loss of endothelial cells was calculated by means of an exponential regression analysis. The findings were compared with those in a homogeneous historical control group (53 patients undergoing homologous penetrating keratoplasty for keratoconus). Results: After autologous rotational keratoplasty relative annual loss of endothelial cells was 1.1% ± 2.6% (mean ± standard deviation). Relative annual loss of endothelial cells in the control-group was 16.7% ± 20.8% . Conclusions: The results of the study lead to the assumption that immunological influences might be the main cause for chronic endothelial cell loss after homologous penetrating keratoplasty.展开更多
