The optic disc is one of the most important structures to diagnose many ocular diseases. From confocal Scanning Laser Opthalmoscope, serial optical sections of optic disc are attained and digital image process techniques are applied. Edges of disc and cap srgin could be detected is each optical section automatically. Computer graphic technique is used to interpolate and to fit the contours into a three-dimensional topography. The parameters include cup to disc ratios, neural ria areas, cup depth, and cup volume could be identified quantitatively. These informations could be used to detect and document the progressive changes in optic disc.
