Binocular combination in abnormal binocular vision.
We investigated suprathreshold binocular combination in humans with abnormal binocular visual experience early in life. In the first experiment we presented the two eyes with equal but opposite phase shifted sine waves and measured the perceived phase of the cyclopean sine wave. Normal observers have balanced vision between the two eyes when the two eyes' images have equal contrast (i.e., both...
متن کاملValue of abnormal retinal correspondence in binocular vision.
ABNORMAL retinal correspondence has been a vexed subject since the physiology of binocular vision and strabismus have been discussed, but it seems to be generally accepted that it is an adaptation of the sensory relations of the retina to the squinting position. Normal retinal correspondence is present when any pair of corresponding points have a common visual direction; abnormal retinal corres...
متن کاملEye position stability in amblyopia and in normal binocular vision.
PURPOSE We investigated whether the sensory impairments of amblyopia are associated with a decrease in eye position stability (PS). METHODS The positions of both eyes were recorded simultaneously in three viewing conditions: binocular, monocular fellow eye viewing (right eye for controls), and monocular amblyopic eye viewing (left eye for controls). For monocular conditions, movements of the ...
متن کاملResidual binocular interactions in the striate cortex of monkeys reared with abnormal binocular vision.
We investigated the nature of residual binocular interactions in the striate cortex (V1) of monkey models for the two most common causes of visual dysfunction in young children, specifically anisometropia and strabismus. Infant rhesus monkeys were raised wearing either anisometropic spectacle lenses that optically defocused one eye or ophthalmic prisms that optically produced diplopia and binoc...
متن کاملBinocular interactions in normal and anomalous binocular vision: effects of flicker.
Temporal modulation thresholds were determined for monocular viewing and for binocular viewing of stimuli presented in phase or in counterphase to each eye of observers with normal binocular vision and those lacking stereopsis. The results showed that in individuals with normal binocular vision sensitivity was much greater for in-phase than for counterphase stimulation at low temporal frequenci...
