Disconjugate eye movements.
To foveate targets in different depths, the movements of the two eyes must be disconjugate. Fine measurements of eye rotations about the three principal axes have demonstrated that disconjugate eye movements may appear not only in the horizontal, but also in the vertical and torsional directions. In the presence of visual targets, disconjugate eye movements are driven by the vergence system, bu...
متن کاملLatency and duration of eye movements in the horizontal plane.
The electrical method of eye movement recording (EOG) was used to study the reactions of the eyes when subjects attempted to fixate as quickly as possible on light stimuli appearing at various points along the horizontal plane. Each eye was recorded separately, allowing an assessment of the degree of independence of the eyes when reacting in this way. In addition to the data concerning latency ...
متن کاملSystematic perceptual distortion of 3D slant by disconjugate eye movements
When an observer pursues an object moving away from him or her, both eyes rotate in the opposite direction, and this type of disconjugate eye movement can generate eye movement-induced disparities in the case of dynamic objects that are present around the pursuit object. Such disparities are not usually generated by conjugate eye movement. The aim of this study was to determine whether eye move...
متن کاملEye Tracking Detects Disconjugate Eye Movements Associated with Structural Traumatic Brain Injury and Concussion
Disconjugate eye movements have been associated with traumatic brain injury since ancient times. Ocular motility dysfunction may be present in up to 90% of patients with concussion or blast injury. We developed an algorithm for eye tracking in which the Cartesian coordinates of the right and left pupils are tracked over 200 sec and compared to each other as a subject watches a short film clip m...
متن کاملRelations of brain centers to normal and abnormal eye movements in the horizontal plane.
Alan is a visualizing animal intimately related to his environment by the things which he sees in the world around him. His range of vision is increased by movements of the head and body and by deviations of the eyes. It seems probable that in man gaze in the horizontal plane is dominant over that in other directions, and it is such horizontal deviations which will be considered at the present ...
