oculomotor system

oc·u·lo·mo·tor sys·tem

that part of the central nervous system having to do with eye movements; it is composed of pathways connecting various regions of the cerebrum, brainstem, and ocular nuclei, using multisynaptic articulations.

They speculated that in humans such neurological deficits might lead to impairment of the oculomotor system, accommodation, and pupillary light reflex (PLR).

There is no 'lesion'; instead the oculomotor system adapts to oscillate the eyes to generate image motion because it improves contrast sensitivity in infancy.

Infantile (congenital) nystagmus

It is known that oculomotor system is able to predict both position and velocity of occluded target for several hundred milliseconds [[1]].

Prediction of target motion drives oculomotor response during target occlusions

This circuit, the so-called oculomotor system, gives the command for rapid eye movement by way of special nerve cells that produce a short-lived succession of action potentials.

Along with a review of preventative measures, contributors explain age-related changes and diseases of the eyelid, optics, cornea, lens, extracellular matrix of the trabecular meshwork, glial and mobile cells in the Iris, vitreous, retina, retinal pigmented epithelium, choroid, lachrymal gland, and oculomotor system.

Age-related changes of the human eye

The choice of the fovea for fixation is based on the high quality of vision that is provided; the sensation of straight-ahead viewing; and the fact that the fovea is the zero point for the oculomotor system, thus maintaining fixation on the object of regard (Duke-Elder & Wybar, 1973).

The oculomotor system is characterized by the interaction between peripheral reflexes and central motor commands of visual origin.

Developmental differences between elasmobranchs and other vertebrates also hinted that the horizontal oculomotor system might have followed a divergent evolutionary pathway since the origin of jawed fishes (9).

The oculomotor system places and holds the eyes on target by six classes of movements: fixation, vestibular, optokinetic, saccades, smooth pursuit and vergence.

Eye movements: pathophysiology, examination and clinical importance

We found that the first flash occurs at least 80 ms before the attendant saccade when, presumably, the oculomotor system discretely alters a neural reference signal specifying intended direction of gaze.

These are used to measure and record certain human eye movements that are indicators of the presence of diseases, drugs or other conditions that impair the human oculomotor system.
