Computerized meridian perimetry. A preliminary report

By a modification of the display of test points it is possible to use the computerized perimeter "Competer" for meridian testing. The test program gives estimates of the thresholds in two separate rounds, the second starting when the first is completed. Accordingly two profiles are plotted in the meridians tested. Furthermore a smoothed profile is drawn from the mean values of the two rounds. The outcome when testing normal subjects and cases with glaucomatous defects was studied and the stability of thresholds in normals and the decay in scotomatous areas with time is demonstrated.
