With the rapid development of science and technology, computer technology has been widely used in the medical field. Some technologies, including digital image processing technology, machine learning technology and pattern recognition technology, have made an indelible contribution.Research of iris pathological feature extraction algorithm is a new research hotspot after iris recognition. The texture of iris does not have big change in one’s whole life, while some specific characteristics of the iris will change when the human body circumstance changes. People can use these subtle changes to research a deeper and broader space in the medical field to provide the first-hand information to iris diagnosis. According to a serious of researches, people can diagnose the invasion site and the severity efficient.By studying the iris structure feature, iris recognition technology and image processing technology deeply, this article can locate iris inner edge precisely and propose two new methods of extracting and locating the outer edge of iris rapidly and effectively. On the basis of deeply studying the iris pathological features and analyzing crypt, spots, the extract methods have been got. After that the method of locating region according to calculate the mean value of the region of pathological characteristics has been proposed to diagnose the location of lesions.
