Abstract
A study of normal optic papillae investigated the following: the surface of the optic disc, cup and rim surrounding the cup; the depth of the cup; the diameters of the disc and cup; and the width of the rim. Photographs were taken with a stereoscopic fundus camera and analyzed by photogrammetry. There was a positive correlation between: the surface of the disc and the surface of the cup; the surface of the disc and the surface of the rim; the surface of the disc and the depth of the cup; and the diameters of the disc and the diameters of the cup. There was no correlation between the diameter of the disc and the width of the rim. The C/D [cup/disc] ratio was high when the disc was large.
