Development of state-of-the-art PhysioVision head mounted displays (HMDs) is the imaging display backbone of 3001 Eye Care. HMDs allow users to see a computer-generated image that can either be monoscopic (same image both eyes) or stereoscopic (different images for each eye) which combine to create a 3D image.  We have developed an integrated visualization system for stereo retinal images. The system can align left and right stereo images automatically,  with a reasonable success rate.

 

In case of alignment failure, semiautomatic alignment can be employed. The aligned left and right stereo images can be visualized in the conventional parallel setup. Moreover, an anaglyph is computed from the aligned images. The disparity between the left and right stereo pair is computed and is used as the depth cue to render the retinal image. The reconstructed 3D surface of the optic-nerve head can be edited, zoomed, panned, rotated,  and animated, which allows the user to observe the retinal surface from different view angles. On the quantitative side, tools to measure the size, area, and volume of regions of interest are provided. Therefore, the longitudinal study of patient retinal images is finally possible.
