Home Ankylostomlasis Beat Knee Nitrous Fumes ... Site Map Miners’ Nystagmus This is an occupational disease affecting the nerves of the eyes, causing a spasmodic movement of the eyeball, either rotary or from side to side. According to Home Office statistics, nystagmus is the most widely prevalent of all industrial diseases, and is found only among miners. The causes of nystagmus have been given by experts as arising from (a) deficient illumination, (b) the assumed position of the miner at work, (c) noxious gases, (d) neurosis, (e) alteration of light intensity. Symptoms The first symptom is failure of sight. Later the sufferer complains of lights and other objects dancing before his eyes. He then complains of giddiness and headache, particularly across the temples and at the back of the head, inability to see at night, and dread of light. These symptoms are most marked after exertion or stooping. The physical signs of the disease are the characteristic involuntary and irregular rotary movement of the eyeball, and twitching of the eyelids and eyebrows when the man is exposed to any light. One of the most characteristic signs of the disease is the failure of what is known as the dark adaptation sense. This is inability to adapt oneself to darkness on first leaving the light.

Nystagmus wordt veroorzaakt door medische ontregeling in ogen of hersenen. Nystagmus:onmogelijk of tenminste zeer moeilijk om stil te zetten. 2 categorieen: * late onset(verworven) - start 6 maanden na de geboorte - oorzaak verscheidene visuele of neurologische problemen. * early onset - start in de eerste 6 maanden - oorzaak meestal als resultaat van een visueel probleem. Meestal is de nystagmus aanwezig met 3-4 maanden. Nystagmus is geen diagnose, het is een symptoom. De nystagmus is voor kinderen onopvallend in hun beleving. De nystagmus kan soms moeilijk te zien zijn met het blote oog of pas opvallen als de ogen weg bewegen van de rechtuit positie. Meestal is de early onset nystagmus overduidelijk aanwezig. Scheelzien kan een nystagmus veroorzaken. De oorzaken van nystagmus: het meest voorkomende type wordt veroorzaakt door een probleem (cataract,scheelzien)direct na de geboorte, in slechts 1 oog. Men noemt dit ook latent nystagmus omdat het optreed bij 1 bedekt oog. Treedt het op wanneer beide ogen open zijn dan noemt men dit manifest nystagmus , vaak is het zicht in 1 oog minder. De nystagmus vermindert dan ook het zicht in het goede oog. Congenitale nystagmus als beide ogen een visueel probleem hebben na de geboorte. In 10-20% wordt er geen onderliggende oorzaak gevonden, in 80-90% is de nystagmus het resultaat van een onderliggend probleem. De nystagmus verminderd de visus maar vaker is het onderliggende probleem belangrijker voor verminderd zicht.

Nystagmus: What is Nystagmus? Normal (physiological) nystagmus occurs for example when a passenger of a train watches as telegraph poles pass the window. There are over 40 different types of nystagmus (www.theberries.ns.ca/BOTW_archives/nystagmus) but the main division is between Congenital and Acquired Nystagmus. The number of people with congenital nystagmus that suffer from this is much less than those with acquired nystagmus. Web Sites - General Visual Impairments Nystagmus Grade I occurs only when the eyes are directed toward the fast component; grade II occurs when the eyes are also in their primary position; grade III occurs even when the eyes are directed toward the slow component. Head-tilting may decrease the nystagmus and is usually involuntary (toward the fast component in jerky nystagmus, or in such a position to minimize pendular nystagmus). Congenital nystagmus of the pendular type usually accompanies congenital visual impairment (e.g., corneal ...

Understanding Nystagmus Richard L. Windsor, O.D., F.A.A.O. Laura K. Windsor. O.D. Nystagmus is an involuntary rhythmic shaking or wobbling of the eyes. The term nystagmus is derived from the Greek word, “ nystagmus”, which was used to describe the wobbly head movements of a sleepy or inebriated individual. Nystagmus has also been described as “dancing eyes” or “jerking eyes”. Doctors and researchers classify nystagmus by the characteristics of the eye movements like do they move back and forth like a pendulum or do they move slowly in one direction and then rapidly in another. Do the eyes move laterally or vertically and by how much? How fast do the eyes move? There are various methods of classifying nystagmus. Traditionally nystagmus has been divided into two groups. Sensory nystagmus is related to vision loss and motor nystagmus is related to the control of muscle function. There are over 45 types of nystagmus. To simplify our explanation of nystagmus, we will divide nystagmus into two basic types. The first is nystagmus that begins very early in life and is associated with vision loss. The second is called acquired nystagmus and is associated with neurological disorders occurring later in life. Nystagmus from Early in Life Early onset nystagmus often accompanies vision loss acquired at birth or soon after and may be one of the first signs that a child has a loss of vision. Studies suggest 1 in every 1000 children have nystagmus. In 80-90% of cases, it is a side effect of vision loss from eye diseases such as albinism, aniridia, optic nerve hypoplasia, achromatopsia congenital cataracts, coloboma or retinopathy of prematurity. This type of nystagmus is usually observed around the sixth to eighth week of life and is rarely seen before then. In about 10-20% of cases, it presents with mild vision loss not associated with other diagnosed ocular diseases. The discovery of nystagmus in a child is reason for an immediate examination!

Congenital and Early Onset Nystagmus This form has many causes, sometimes genetic and often linked to other eye problems. It occurs in the very young, persisting for the rest of the individual's life. Horizontal Nystagmus The eyes move back and fore. Jerk Nystagmus Type of eye movement where the eyes accelerate as they move. Latent Nystagmus Condition appears when one eye is covered up. Manifest Latent Nystagmus Is visible all the time because one eye is 'covered' by some other form of impairment such as a cataract. Rotatory Nystagmus The eyes move round and round. Pendular Nystagmus Is thought to be a result of a delay in messages to the brainstem. It can be congenital or acquired and is characterized by eye movements that are equally paced in each direction. Oscillations may be vertical, horizontal, diagonal or rotary. There also exists a fast and slow phases to the waveform. Vertical Nystagmus The eyes move up and down.

93. WolfeClinic - Iowa WHAT IS nystagmus? nystagmus is an involuntary, rhythmical, repeatedoscillations of one or both eyes, in any or all fields of gaze. http://www.wolfeclinic.com/ped_nystagmus.asp

WHAT IS NYSTAGMUS? Nystagmus is an involuntary, rhythmical, repeated oscillations of one or both eyes, in any or all fields of gaze. It may be pendular (with undulating movements of equal speed, amplitude, and duration, in each direction) or jerky (with slower movements in one direction, followed by a faster return to the original position). Movements may be horizontal, vertical, oblique, rotary, circular, or any combination of these. Many conditions are associated with nystagmus. Sometimes, the brain's control of eye movements is poor, resulting in an inability to look steadily at an object. Some forms of nystagmus are associated with reduced vision, such as occurs in albinos, extreme near of farsighted people, or in those with scars in the retina or optic nerve. Rarely, nystagmus can occur as a result of brain tumors or in serious neurololgic disorders. Nystagmus can be found in families as an isolated problem, not associated with other conditions. A thorough evaluation by an ophthalmologist and perhaps other medical specialists is very important. Some forms of nystagmus have a definite cause. Important clues relate to age of onset, family history, general health of the patient, or the use of certain medications. Your ophthalmologist may examine the pattern of the nystagmus, its speed and direction and look for other eye problems such as a droopy lid, cataract, or an abnormality of the retina or optic nerves. Blood test or special x-rays may be useful in determining the cause.

Disease Injury Nutrition Poison ... External and internal eye anatomy Eye movements - uncontrollable Definition: Uncontrollable eye movements are involuntary, rapid, and repetitive movement of the eyes. Alternative Names: Back and forth eye movements; Involuntary eye movements; Nystagmus; Rapid eye movements from side to side; Uncontrolled eye movements Considerations: Nystagmus refers to rapid involuntary movements of the eyes that may be from side to side (horizontal nystagmus), up and down (vertical nystagmus) or rotary. Depending on the cause, these movements may be in both eyes or in just one eye. The term "dancing eyes" has been used in regional dialect to describe nystagmus. The involuntary eye movements of nystagmus are caused by abnormal function in the areas of the brain that control eye movements. The exact nature of these disorders is poorly understood. Nystagmus may be either congenital (present at birth) or may be acquired (caused by disease or injury later in life). CONGENITAL NYSTAGMUS Congenital nystagmus is more common than acquired nystagmus. It is usually mild, does not change in severity, and is not associated with any other disorder.
