title: Electrophysiological and psychophysical testing of vision in glaucoma.
abstract: Electrophysiological testing in patients with early glaucoma and in glaucoma suspects reveals defects of central or foveal vision. Most studies suggest that glaucomatous eyes are best separated from normal eyes by use of stimuli with a spatial frequency below the peak of the human contrast sensitivity curve and a relatively high temporal frequency. The stimulus-dependent abnormalities in glaucoma are generally consistent with contrast sensitivity data The stimulus-dependent visual changes are related to the physiology of parallel processing in the primate retinogeniculate pathway.
