It is well established that dopaminergic deficiency in the visual system dominantly and specifically disrupts spatiotemporal contrast sensitivity functions.2 There is some evidence that this impairment is most pronounced for the transient visual channels, which are related to the processing of stimuli with low-spatial and high-temporal frequencies.3 Therefore, studies investigating contrast-sensitivity functions in patients with schizophrenia can be specifically confounded by uncontrolled antidopaminergic medication effects.
