Abstract
We have described a computer-controlled technique to assess Wald-Marré functions. The background fields are similar in spectral composition to those used by previous authors, however flicker rather than discrete flashes was used for the test stimulus. For estimation of long- and middle-wavelength cone sensitivities, a flicker rate of 15 Hz was used; for the short, 2.4 Hz was used.
A computer-controlled psychophysical tracking method was used to obtain thresholds for test wavelength presentations. This method allowed a single cone sensitivity curve to be obtained in a short period of time (10–15 min). It can be used clinically as a fast and easy method to obtain relative cone sensitivities for patients.
