Le nystagmus est une perturbation de la coordination des muscles de l'œil. Il peut être causé par une pathologie, des mouvements très rapides ou l'abus de certaines substances. Les oscillations peuvent se produire dans un plan vertical, horizontal, de torsion ou dans une combinaison de ceux-ci. L'œil se dirige lentement vers une direction, puis revient brutalement à sa position d'origine. La direction du nystagmus est définie comme étant celle du déplacement rapide (cependant, le trouble a d'abord tendance à engendrer le mouvement lent, avant que le mouvement rapide vers la position d'origine n'intervienne pour rétablir la situation). . Nystagmus optocinétique horizontal physiologique.Le nystagmus physiologique est dû à la mise en jeu coordonnée des six muscles oculomoteurs qui assurent normalement à la fois la mobilité et la fixation des globes oculaires. Ces muscles permettent de : Un exemple de nystagmus physiologique est le mouvement des yeux d'une personne assise dans un train et regardant le paysage extérieur défiler à vive allure. Ses yeux essaieront de suivre certains détails tout en se recalant fréquemment au centre de son champ de vision : il s'agit du nystagmus optocinétique, dont les perturbations peuvent être recherchées lors de l'examen clinique neurologique.

Auszug: Nystagmus (aus griechisch ‚Schläfrigkeit', zu nystazō ‚nicken', ‚schlummern') bezeichnet die unkontrollierbaren, rhythmischen Bewegungen eines Organs, üblicherweise jedoch der Augen, so dass unter Nystagmus in der Regel ein Augenzittern verstanden wird. Er kommt physiologisch vor, aber auch pathologisch, z. B. als typisches Symptom des Schwindels. In der Klinik wird der (üblicherweise mit einer Richtung klassifizierte) Nystagmus nach der schnellen Phase der Augenbewegung benannt. Optokinetischer NystagmusDer physiologische Nystagmus dient dazu, das durch die Linse projizierte optische Bild so konstant auf der Netzhaut zu halten, dass eine Wahrnehmung möglich ist. Sowohl Bewegungen des betrachteten Objekts als auch Eigenbewegungen des Auges, des Kopfes und des gesamten Organismus im Raum führen zu Bewegungen des Lichtreizes auf der Netzhaut. Wenn die Winkelgeschwindigkeit dieser Lichtreflexe zu groß wird (>5°/s) kann das Bild nicht mehr scharf wahrgenommen werden. Bei Augen mit einer Retina wie beim Menschen ist es darüber hinaus sinnvoll, den Fokus stets im Bereich des schärfsten Sehens (Fovea centralis) zu halten (siehe dazu Blickbewegung). Ein Beispiel für einen physiologischen Nystagmus ist der optokinetische Nystagmus, der auftritt, wenn sich Wahrnehmungsobjekte relativ zur Netzhaut kontinuierlich bewegen, etwa beim Blick aus einem fahrenden Zug. Ein Nystagmus kann dagegen auch krankhafte...http://booksllc.net/?l=de&id=198602 ... Read more

Not illustrated. Free updates online. Purchase includes a free trial membership in the publisher's book club where you can select from more than a million books without charge. Excerpt: Ménière's disease (pronounced ) is a disorder of the inner ear that can affect hearing and balance to a varying degree. It is characterized by episodes of vertigo and tinnitus and progressive hearing loss, usually in one ear. It is caused by lymphatic channel dilation, affecting the drainage of endolymph. It is named after the French physician Prosper Ménière, who first reported that vertigo was caused by inner ear disorders in an article published in 1861. The condition affects people differently; it can range in intensity from being a mild annoyance to a chronic, lifelong disability. The symptoms of Ménière's are variable; not all sufferers experience the same symptoms. However, so-called "classic Ménière's" is considered to comprise the following four symptoms: Ménière's often begins with one symptom, and gradually progresses. However, not all symptoms must be present for a doctor to make a diagnosis of the disease. Several symptoms at once is more conclusive than different symptoms at separate times. Attacks of vertigo can be severe, incapacitating, and unpredictable. Attacks of vertigo last no longer than 24 hours. This combines with an increase in volume of tinnitus and temporary, albeit significant, hearing loss. Hearing may improve after an attack, but often becomes progressively worse. Nausea, vomiting, and sweating sometimes accompany vertigo. Some sufferers experience what are informally known as "drop attacks"a sudden, severe attack of dizziness or vertigo that causes the sufferer, if not seated, to fall. Patients may also experience the feel...More: http://booksllc.net/?id=55994 ... Read more

Product Description
High Quality Content by WIKIPEDIA articles! High Quality Content by WIKIPEDIA articles! Positional alcohol nystagmus (PAN) is nystagmus (visible jerkiness in eye movement) produced when the head is placed in a sideways position. PAN occurs when the specific gravity of the membrane space of the semicircular canals in the ear differs from the specific gravity of the fluid in the canals because of the presence of alcohol. When a person consumes alcohol, the alcohol is carried by the bloodstream and diffused into the water compartments of the body. Normally, the specific gravity of a canal membrane is the same as the the specific gravity of the surrounding fluid. Because of this, even though the Earth's gravity is a constant force of acceleration, the semicircular canals do not respond to it. Alcohol has a lighter specific gravity than water. ... Read more

Product Description
High Quality Content by WIKIPEDIA articles! High Quality Content by WIKIPEDIA articles! Physiologic nystagmus is a form of involuntary eye movement that is part of the vestibulo-ocular reflex (VOR). It is characterized by alternating smooth pursuit in one direction and saccadic movement in the other direction. Nystagmus can be caused by subsequent foveation of moving objects, pathology, sustained rotation or substance use. For example, if one fixates on a stripe of a rotating drum with alternating black and white, the gaze retreats to fixate on a new stripe as the drum moves. This is first a rotation with the same angular velocity, then returns in a saccade in the opposite direction. The process proceeds indefinitely. This is optokinetic nystagmus, and is a source for understanding the fixation reflex. ... Read more
