Clinical spatial contrast sensitivity measurement: implications of artificial scotoma experiments.
Measurement of spatial contrast sensitivity in normal subjects showed that the change produced by an artificial central scotoma depended on temporal factors associated with grating presentation. Minimizing temporal transients produced a predominantly high spatial frequency loss. Accentuating temporal transients produced an additional low spatial frequency change in sensitivity.
