Objective measurement of contrast sensitivity function using contrast sweep visual evoked responses.
AIM/BACKGROUND The contrast sensitivity function (CSF) measurement provides information that is not accessible by standard visual acuity determinations. The contrast sweep pattern reversal visual evoked responses (CSVER) technique was used to objectively measure the CSF in clinical practice. METHODS The contrast thresholds were measured at five spatial frequencies in 10 normal subjects. The C...
متن کاملHow arousal modulates the visual contrast sensitivity function.
Recent evidence indicates that emotion enhances contrast thresholds in subsequent visual perception (Phelps, Ling, & Carrasco, 2006) and perceptual sensitivity for low-spatial frequency but not high-spatial frequency targets (Bocanegra & Zeelenberg, 2009b). However, these studies just report responses to various frequencies at a fixed contrast level or responses to various contrasts at a fixed ...
متن کاملVisual evoked potential and contrast sensitivity function in diabetic retinopathy.
survival in elderly patients but enormously enhances the quality of remaining life. How often hypopituitarism is responsible for postural hypotension is unclear, but pointers seen in our patients included low serum thyroxine concentrations without the expected raised thyroid stimulating hormone, hyponatraemia, and disproportionately pale facies. Visual evoked potential and contrast sensitivity ...
متن کاملKnowledge alters visual contrast sensitivity.
Research has shown that the visual system's sensitivity to variations in luminance (visual contrast) within a particular area of the retina is affected in a bottom-up fashion by the ambient contrast levels in nearby regions. Specifically, changes in the ambient contrast in areas surrounding the target area alter the sensitivity to visual contrast within the target area. More recent research has...
متن کاملVisual contrast sensitivity in drug-induced Parkinsonism.
The influence of stimulus orientation on contrast sensitivity function was studied in 10 patients with drug-induced Parkinsonism. Nine of the 10 patients had at least one eye with contrast sensitivity deficit for vertical and/or horizontal stimuli. Only generalised contrast sensitivity loss, observed in two eyes, was stimulus orientation independent. All spatial frequency-selective contrast def...
