ABSTRACT:
A process and apparatus for dynamic or static perimetry of the human eye wherein topographical measuring threshold values of eye sensitivity for the eye being tested are obtained and are electronically compared with stored standard values of eye sensitivity corresponding to the testing conditions. An indication is provided of deviations between the measured values and the stored standard values. The apparatus includes a perimetry device, a computer for storing the standard values and at least one program for controlling the perimetry device and for comparing the measured values with the stored standard values and a display arrangement for displaying the values and deviations.
