Contrast sensitivity during the initiation of smooth pursuit eye movements
Eye movements challenge the perception of a stable world by inducing retinal image displacement. During saccadic eye movements visual stability is accompanied by a remapping of visual receptive fields, a compression of visual space and perceptual suppression. Here we explore whether a similar suppression changes the perception of briefly presented low contrast targets during the initiation of s...
متن کاملTemporal contrast sensitivity during smooth pursuit eye movements.
During smooth pursuit eye movements, stimuli other than the pursuit target move across the retina, and this might affect their detectability. We measured detection thresholds for vertically oriented Gabor stimuli with different temporal frequencies (1, 4, 8, 12, 16, 20, and 24 Hz) of the sinusoids. Observers kept fixation on a small target spot that was either stationary or moved horizontally a...
متن کاملEffect of eye movements on dynamic equilibrium.
The purpose of this study was to determine whether visual improvement of balance varies depending on the movement of the eye. Three movements were compared: static visual fixations, saccadic eye movements, and smooth pursuit eye movements. The subjects in this study were 35 healthy female volunteers. Balance was defined as the subjects' ability to maintain their equilibrium while keeping the un...
متن کاملEffects of contrast on smooth pursuit eye movements.
It is well known that moving stimuli can appear to move more slowly when contrast is reduced (P. Thompson, 1982). Here we address the question whether changes in stimulus contrast also affect smooth pursuit eye movements. Subjects were asked to smoothly track a moving Gabor patch. Targets varied in velocity (1, 8, and 15 deg/s), spatial frequency (0.1, 1, 4, and 8 c/deg), and contrast, ranging ...
متن کاملContrast Sensitivity and Eye Drops
Purpose: To evaluate the influence of commonly used eye drops on contrast sensitivity (CS). Design: Prospective study. Participants: One hundred twenty volunteers were enrolled. Methods: The CS of ophthalmologically healthy individuals was evaluated at baseline examination before the instillation, 20 and 40 minutes after the instillation of diclofenac sodium and commonly used anti-glaucoma eye ...
