Sudden nystagmus, shaking of vision in adults, what is going on

He's looking at things with his eyes fluttering.

nystagmus (nystagmus; ny) is an involuntary, rhythmic, back-and-forth eye movement. The direction is divided into horizontal, vertical, and rotational type, with the horizontal type being the most common, usually the fast-phase direction indicating the direction of nystagmus, and the fast-phase being the compensatory recovery of fixation movement. Referred to as nystagmus.

It is often caused by diseases of the visual system, extraocular muscles, labyrinth of the inner ear, and the central nervous system. Nystagmus is not a stand-alone disease, but a clinical manifestation of certain diseases, so it should be targeted.

**。Ocular nystagmus.

Refers to the central vision impairment of the macula, which is caused by difficulty in forming the fixation reflex.

1) Physiological fixation nystagmus includes oblique nystagmus, visuodynamic nystagmus and recessive nystagmus.

2) Pathological fixation nystagmus includes blind nystagmus, amblyopia nystagmus, occupational nystagmus, etc.

2.Vestibular nystagmus.

3.Central nystagmus.

4.Congenital idiopathic nystagmus.

Clinical presentation. 1.Run-out type.

The eyeball moves back and forth at a marked different speed, and when the eye slowly turns in the other direction to a certain extent, it suddenly returns in a rapid movement. This type of tremor has chronic and fast phases, with chronic being physiological and fast being corrective movements. The fast phase direction is the direction of nystagmus, and the fast phase is related to **.

2.Swing type.

The swing of the eyeball is like a pendulum, there is no fast phase and no slow phase. Its velocity and amplitude are equal. It is more common in patients with dark eyes and amblyopia.

How to check. 1.General examination.

Have the patient look straight ahead and observe the nystagmus as they follow the examiner's finger in a certain direction. Some require a single eye covering for examination. To this end, the following points should be taken into account during the inspection:

1) Whether it is recessive or latent, or overt nystagmus.

2) Whether the nystagmus is joint - whether the movements of the two eyeballs are consistent with each other or dissociated.

3) The type, direction, degree, frequency, amplitude of nystagmus, etc.

4) There are endless eye positions.

2.Special examinations.

Nystagmus galvanogram and other instrument examinations.

I believe we all know that nystagmus is a common movement disorder, mainly the nystagmus will occur in the eyeball part, nystagmus is generally aggravated when concentration, mental tension, fatigue, hunger, which is also nystagmus, nystagmus clinical characteristics, Chinese medicine believes that nystagmus is a disease ** is, "liver wind internal movement, liver meridian insufficiency" caused.

Nystagmus is a condition called familial nystagmus, and most people with this nystagmus have a family history. No intergenerational phenomenon has been observed in multiple nystagmus families. Typical nystagmus can be found in children, adolescents, middle-aged and older adults, and the incidence of nystagmus in the general population is very low and increases with age.

There is no significant difference in incidence between men and women.

The first and the mechanism of nystagmus are complex and uncertain, which may be caused by congenital genetic factors, or may be the clinical manifestations of other ocular and otogenic diseases. Genetic factors and environmental factors are both involved in the pathogenesis.

First, the main **.

1. Oculogenic nystagmus: refers to nystagmus caused by the impaired optic hall in the central hall of the macula, which makes the fixation reflex difficult.

2. Vestibular nystagmus: nystagmus caused by lesions in the vestibular nucleus or its communication pathways with the cerebellum or brainstem.

3. Central nystagmus: more common in bulbar lesions, pontine lesions, midbrain lesions and cerebellar lesions.

4. Congenital essential nystagmus: a congenital disease, which is currently unknown and needs further research.

5. Others: may be related to heredity, with X-linked recessive inheritance being the most common, manifested as parents with disease, and children with high risk of disease. Some eye shocks can be caused by drugs or toxic substances.

2. Predisposing factors.

1. Usually blinking, resulting in eye muscle nerve fatigue and paralysis, which can congenitally induce nystagmus.

2. Maintaining an action for a long time can lead to fatigue and paralysis of eye muscles and nerves, which can congenitally induce nystagmus.

3. Congenital amblyopia, the eye itself is not perfectly developed, and it is very easy to have congenital nystagmus.

Symptoms of nystagmus:

1. What can be seen, the eyesight is reduced;

Clause. Second, the eyeball shows an involuntary swing or beating, and the patient will say that the eye is old and does not rest, and it is shaking;

Clause. Third, it is manifested that there is a head position, and some patients have a head position, that is, to see things with their heads tilted, turning their faces left or right, looking up at their necks, looking down, tilting their heads to the right shoulder, tilting their heads to the left shoulder, all kinds of head positions, this kind of head position cannot be corrected, and surgery is required to correct this head position, so if you have nystagmus, you must find a professional doctor as soon as possible to see, what kind of head position is the head position, and how to do surgical correction, so as not to make the child's spine abnormal development, long-term crooked, and the neck will be crooked. The face is also asymmetrical, with one side large and one side small, which can cause this problem.

But don't worry, as long as there is a problem, it can be solved by surgery this kind of head position, about nystagmus should also pay attention to one point, whether it can be done without tremor, the current level of science and technology can not be reached, can be reduced, in fact, its ** amplitude is getting smaller and smaller, and the frequency of tremor is getting lower and lower.
