[Stereophotography and photogrammetry of the physiological cup of the disc (author's transl)].

Researches related in this study were done on normal optic papillae. Their aim is to measure: a) the surface of the optic disc, the surface of the cup and the surface of the rim surrounding the cup; b) the depth of the cup; c) the diameters of the disc, the diameters of the cup and the width of the rim. Photographs were taken with a stereoscopic fundus camera and analysed by photogrammetry. There is a positive correlation between: a) the surface of the disc and the surface of the cup; b) the surface of the disc and the surface of the rim; c) the surface of the disc and the depth of the cup; d) the diameters of the disc and the diameters of the cup. There is no correlation between the diameter of the disc and the width of the rim. The ratio C/D is high when the disc is large.
