This report focuses on fundamental findings appropriate to this initial stage of our work. We look forward to making more detailed recommendations later this year. Based on our review of federal government and other research done to date, we have reached the following conclusions and recommendations.

Extractions: NYSTAGMUS Under Construction Timothy C. Hain, MD Education Index Search this site Nystagmus is defined as involuntary movement of the eyes. Most frequently it is composed of a mixture of slow and fast movements of the eyes. Nystagmus can occur normally, such as when tracking a visual pattern. Nystagmus may also be abnormal, usually in situations where one would want the eyes to be still, but they are in motion. Vertigo (a sensation of spinning), is often accompanied by nystagmus. The following material attempts to illustrate and describe nystagmus subtypes. Convergence/Retraction nystagmus Divergence nystagmus Periodic alternating nystagmus (PAN) Central nystagmus (downbeat, upbeat nystagmus, horizontal, torsional) Saccadic Nystagmus EVOKED NYSTAGMUS Head-shaking nystagmus (HSN) Caloric nystagmus Optokinetic Nystagmus (OKN) Positional Nystagmus Typical appearance of vestibular type spontaneous nystagmus.
Nystagmus Rhythmic, oscillating motions of the eyes are called nystagmus. nystagmus canbe a normal physiological response or a result of a pathologic problem. http://www.chclibrary.org/micromed/00058730.html
Extractions: Rhythmic, oscillating motions of the eyes are called nystagmus. The to-and-fro motion is generally involuntary. Vertical nystagmus occurs much less frequently than horizontal nystagmus and is often, but not necessarily, a sign of serious brain damage. Nystagmus can be a normal physiological response or a result of a pathologic problem. Description The eyes play a critical role in maintaining balance. They are directly connected to other organs of equilibrium, most important of which is the inner ear. Paired structures called the semicircular canals deep in the skull behind the ears sense motion and relay that information to balance control centers in the brain. The eyes send visual information to the same centers. A third set of sensors consists of nerve endings all over the body, particularly in joints, that detect position. All this information is integrated to allow the body to navigate in space and gravity. It is possible to fool this system or to overload it with information so that it malfunctions. A spinning ride at the amusement park is a good way to overload it with information. The system has adapted to the spinning, expects it to go on forever, and carries that momentum for some time after it is over. Nystagmus is the lingering adjustment of the eyes to tracking the world as it revolves around them.
Extractions: Involuntary movements of the eye that are divided into two types, jerk and pendular. Jerk nystagmus has a slow phase in one direction followed by a corrective fast phase in the opposite direction, and is usually caused by central or peripheral vestibular dysfunction. Pendular nystagmus features oscillations that are of equal velocity in both directions and this condition is often associated with visual loss early in life.

Extractions: If the patient has a vertical nystagmus (upward or downward) he will see things turning around a horizontal bitemporal axis. If he has a type of rotatory nystagmus, things will move about a horizontal anteroposterior axis. These are the most frequently observed types of nystagmus. Occasionally we see an oblique nystagmus which seldom is a very neat one. The second thing that we notice is the "intensity." It has been graded as "F irst degree " when the nystagmus is only visible during gaze in the direction of the quick component. " Second degree " when the nystagmus is present on forward gaze, and "T hird degree " when present during gaze also in the direction of the slow component.
