Abstract
The relationship between CFF and age is linear and negative for all light:dark ratios (LDR) under both conditions of surround luminance. The decrement in CFF with age is a function of the light-time percentage of the flicker cycle. "On the basis of the results it was suggested that the use of lower levels of light-time in the flicker cycles, rather than the conventional 50:50 LDR, would enhance the sensitivity of CFF as an indicator measure." 16 refs.Keywords
