Abstract
The anxiolytic lorazepam was studied for its effects on contrast sensitivity to gratings flickering in counterphase in normal volunteers. The drug significantly reduced contrast sensitivity at low spatial frequencies in a dose-related manner. The results are discussed with reference to possible GABA-mediated processes in the retina and lateral geniculate nucleus.
