By observing iris, someones body condition can be known, such as his/her status is weak or strong, health stage, and the changes to illness or curing process. Therefore, a research is required to develop a computerized identification system for iris image in order that the condition of someone can be known. In this research, cholesterol excess that will be examine in the body which is identified by existing of white circle/sodium circle in iris. In this research, after the technician take the patient iris image, this information then saved to the database technician and transmitted to the doctor application program. The doctor application program, identify cholesterol excess based on iris image observation. The process stages are data acquisition, preprocessing, if needed, to reduce noise or control the image intensity, and feature extraction. The algorithm used for feature extraction is threshold which is continued with transformation to polar coordinates. The test is performed using Matlab 7.0 and mySql software. After passed several repeated test, a conclusion can be taken that is the program will recognize patient eyes which have cholesterol excess in his/her body if threshold of amount of post processing white pixel is more than 1000. If the threshold is less than 1000 will be identify have normality cholesterol.
