title: Clinical spatial contrast sensitivity measurement: implications of artificial scotoma experiments.
abstract: 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.
