Nystagmus Positions

Positional nystagmus is a symptom of a disease or pathological process in the tissues of the peripheral nervous system, observed when the stem structures and thalamus are damaged, but is always one-sided. In humans, it is characterized by involuntary movements of the eyeballs. When the patient's orbit is closed, a "thread" symptom occurs. This is a rapid nystagmatic movement of the eyes due to contractions of the extraocular muscles, the muscle abducts the eye, then returns it back.

Nystagmus is also called uncontrolled chaotic contractions of the eye muscles. They can be constant or episodic. Sometimes nystagmatic syndrome develops due to drug intoxication, alcohol or drug use

Positional nystagmus is usually called a stable nystagmatic movement of the eyeball, as if jumping over the same places in the patient’s field of vision. Most often, such a nystagmic oscillation is noticeable when examining a patient in a supine position. This movement of the eyelids may be a sign of encephalitis. Acute meningitis usually does not produce nystagmus, however, it can be quite difficult to differentiate these diseases, since due to a decrease in the sensitivity of the pupils, many reflex movements in patients may be absent, but reflex eye movements are also not always found. Positional nystagmus is most often preceded by an ordinary, smooth one. However, this oscillatory movement is almost always more energetic and noticeable than smooth nystagmus. The next difference is that after the cessation of smooth nystagmus, vision is quickly restored, whereas after the cessation of positional nystagmus, blurred vision is observed for a long time, which is gradually completely restored. Due to the peculiarities of the clinical course, treatment of nystagmus will differ for each form of the disease. For smooth nystagmus, it is aimed at general strengthening of the body, and with positional nystagmus, the main role is played by the task of maintaining muscle tone. Treatment for nystagham directly depends on its cause. **When a person came to me for the first time with complaints about the nystagmatic activity of his pupillary reflexes and began to regress, the possibility of prescribing a single drug treatment became impossible**, and alternative drugs could affect him, or an intolerable combination of “speculations about the correctness of the choice of certain therapeutic funds." In principle, his life activity should not be limited
