The importance of these two observations in following glaucoma patients is certainly without question. Dr. Schwartz suggests that stereo-photography of the discs is the best way of recording these observations. Lacking availability of stereo-photography, he recommends a scheme of drawing the optic nerves to depict the cupped areas and the pallor.As a practical matter, neither of these two methods is entirely satisfactory for the practitioner. Stereo-photographs require that these be available, with a satisfactory stereoviewer, at the time of the visit of each glaucoma patient. This probably entails double filing and possible delays in examining each glaucoma patient. Drawings are not very satisfactory either because of the inability of most
