This paper describes a method of three-dimensional (3-D) optic disk reconstruction from a pair of stereo images. This is achieved through the implementation of various procedures that further enhance the accuracy including camera calibration, constraint-based combined registration, dense-depth recovery, and eye-optics inclusion. A combination of two registration methods is applied to precisely detect the correspondences, which are then converted into depths. The optical effect of light media within the eyeball is considered. A new method is proposed to calibrate and integrate this effect into the reconstruction process to provide an accurate 3-D image of optic disk. Compared with the result from Heidelberg Retina Tomograph (HRT), the 3-D image reconstructed by the proposed method shows good consistency and compatibility which indicates that it could be used as an alternative mode of 3-D viewing of the optic nerve head
