By using the system, we can perform the iris configuration quantitative measurement in living eyes. The measuring parameters including: iris rest length,radius of iris curvature,and the thickness in different parts of iris. Ten anterior segment images of one normal individual were obtained by a single operator to evaluate the intraobserver reproducibility of image capture, and ten times measurement of one image were performed by a single operator to assess the reproducibilityof image measurement.
