Abstract : The tubular shape and tightly encapsulating orbit of the owl's eye would seem to make horizontal and vertical eye rotations impossible. The amazing flexibility of the neck, allowing the head to rotate 270 degrees on the torso, would seem to make eye movements unnecessary.

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.

SummaryIn a simplified fashion, the motion of the eyeball in its orbit consists of rotations around a fixed point. Therefore, this motion can be described in terms of Euler's angles of rigid body dynamics. However, there is a physiological constraint in the motion of the eye which reduces to two its degrees of freedom, so that one of Euler's angles is ...

Practical Neurology, 2007
As with all aspects of the neurological examination, important clues come from a thorough and appropriate history. In relation to eye movement disorders the patients may be complaining of double vision, in which case they should be asked whether it is constant or intermittent; does it occur, or is it maximal, in certain directions of gaze; what is the ...

Ocular Bobbing: Abnormal Eye Movement or Eye Movement’s Abnormality?
Ophthalmologica, 1983Ocular bobbing is classified as an abnormal eye movement, resulting from pathological neuronal activity of the brain stem after bilateral pontine lesions. Clinical oculographic study of 5 patients suffering from ocular bobbing shows that upwards voluntary eye movements are abnormal.

The extensive and scattered literature on vergence eye movements is reviewed. Topics covered include the neural innervation to vergence, active versus passive divergence, muscular control, the accuracy of vergence, the interaction from vergence to accommodation, the independence of vergence and version, the sharing of responsibility with other eye ...

Vergence eye movements refer to the binocular, nonconjugate, disjunctive ('fusional') movement of the eyes used to track objects moving in depth to maintain bifoveation and fused/single vision. They can be horizontal, vertical, and/or cyclorotary in nature.
