Jedynak et al. 1994 . Do's and don'ts in Fourier analysis , Significance of steady-state responses . Visual acuity is one of the most common ophthalmological examinations. Glaucoma is one major reason for blindness in Germany. We examine electrophysiological and psychophysical tests for their viability to detect glaucoma in an early stage.
Research is to a marked degree driven by methodology.
Currently, we develop all new experiments on Macintosh computers, like the Freiburg Visual Acuity Test . For vision research experiments, the stimuli are now being based on the Apple Game Sprockets which makes things much easier. In 2000 we moved to a Macintosh-based new fully integrated evoked potentials program developed by Michael Bach after 2 months overlap with the previous version. ERG measurement is based on a custom Pascal program written by Ulrich Schilling on another old PC, driving a Nicolet stimulator. Currently, the ERG is rewritten by Uwe Jendricke in Igor .
