title: Rapid detection of changes in the optic disc: stereo-chronoscopy.
abstract: Easy detection of temporal variations of tissue configurations within the optic disc or other structures is possible by means of stereoscopy: Stereochronoscopy. Photographic pictures of the papilla are taken from time to time at exactly the same angle; when any two of them are paired and viewed with a stereoscope, temporal form changes immediately show up as stereo effects (Schirmer [2]). Since continuing glaucomatous damage cannot be diagnosed either by visual field defects or by actual c/d ratios but only by their temporal changes, this method may prove of diagnostic value.
