title: Numerical grading of the disc.
abstract: The current method of grading the optic disc cannot replace stereoscopic photography. The present method of describing the optic disc is misleading and does not supply as much information as could be provided. The proposed method adds both vertical and horizontal dimensions. It takes very little time to record and supplies both the reader and subsequent examiner with a more detailed description of the disc, cup, disc ratio.
