[Contrast sensitivity function. Results of an epidemiologic study].
The examination of contrast sensitive function partially tests the capabilities of ganglion cells. However, this method has not yet proven to be an unquestionable way of diagnosis, 108 Subjects with various pathological conditions were tested with this technique in order to confirm its value for ophthalmological pathology. The first epidemiological results show that there are changes in curves obtained for clinically sick patients, and that the currently used equipment is most sensitive of the 4 th frequency and high frequencies. Finally, each colored stimulation is very significant at low frequencies.
