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.

Abstract: A perimetric eye examination device is provided having light-emitting diodes for the respective light sources which are perceived during the eye examinations. These light-emitting diodes are controllable for their brightness, either in linear dependence on the current, or in linear dependence on the pulse width repetition ratio of current pulses supplied to the light-emitting diode. The brightness perceived from the respective light-emitting diodes on the surface of the perimetric eye examination device also may be varied in accordance with physiological characteristics of the eye wherein the light-emitting diodes are distributed on the surface of the device with the brightness increasing from the central area of the observation area toward the periphery of the observation area.
