Efforts have been made to improve the capability of tonography in differentiating normal from glaucomatous eyes. Leydhecker proposed that the quotient P3 C(3-7), obtained from a seven-minute tonographic test, was more reliable for this purpose than any other mathematic value. To test this hypothesis, 152 normal, ocular hypertensive, and glaucomatous eyes were subjected to this seven-minute procedure. With the aid of computer processing, P0, P3, P0 C(0-4), P3 C(3-7), and P0 C(0-7) were obtained. Analysis of data indicated that P0 C(0-4) was significantly more sensitive than the other statistics. In addition, results of this study compared favorably with Becker's work on the distribution of C(0-4) and P0 C(0-4) between normal and glaucomatous populations.
