Abstract
In order to register the electroretinotopogram (ERTG) as a measure for local retinal sensitivity, a stimulator has been developed able to present light stimuli with a flicker frequency of 40 Hz at any point within the 90° visual field of the eye. Size and luminance of the test light can be varied. Stray light effects are suppressed by applying a 30° adaptation field around the test light. Positioning of the stimulus is done with an easy to operate coordinating table, the output of which steers an electronic position servo system.
The results are promising, but a number of problems still have to be solved before the instrument can be fully accepted for clinical use.
