- Brief summaryTo determine the influence of dynamic light conditions on visual functioning in glaucoma. For this purpose we measure (1) the contrast sensitivity to a small stimulus at a time-varying background luminance and (2) the critical fusion frequency (CFF), which is the highest frequency of flicker that can be distinguished from steady state (temporal sensitivity), as a function of background luminance.
