Abstract :
An effective method for the analysis of donated corneas consists in the evaluation of the indexes of cellular density, pleomorphism and polimegatism. We have developed a system attached to the slit lamp and dedicated software for image treating and analysis of the referred indexes using the mathematical morphology procedure. The results of automatic determination of the cellular density has a correlation coefficient of 0.95798 compared to measurements done by the interactive counting method and for the polimegatism and pleomorphism indexes the preliminary visual results are in good agreement with the presented processed image
