Is nystagmus a constant tremor? What is the problem with nystagmus?

Nystagmus is an involuntary, rhythmic, pendulum-like or beating-like oscillation of the eyeball. The main causes of nystagmus are early eye motor dysplasia, such as congenital cataracts, which cause nystagmus, as well as family genetic history, Down syndrome, brain damage, or lesions, such as inflammation of the brain, tumors, degeneration, trauma, and vascular diseases, which may cause nystagmus. In addition, nystagmus can be caused by eye disease or eye dysfunction, degenerative changes of the optic nerve, severe astigmatism, high myopia, physical diseases, multi-site sclerosis, stroke, and severe ear inflammation.

Some poisonings can also cause nystagmus, such as sedative poisoning, antipsychotic poisoning, bromide poisoning, etc., alcoholism, albinism are also one of the causes of nystagmus. Sometimes nystagmus is not defined** and may also be affected by mental and physical strength, such as stress, fatigue or nervousness.

Nystagmus is strictly a symptom, not a disease, and is usually caused by pathological changes in the eye and abnormalities in the fundus. Or if you are in a dark environment for a long time, the cones that sense light are inhibited, and the eyes will lose their ability to fix their vision and tremble. Nystagmus can also be caused by paralysis of the eye muscles or dysfunction of the vestibular system.

Nystagmus is an involuntary, rhythmic, back-and-forth eye movement. It is often caused by diseases of the visual system, extraocular muscles, labyrinth of the inner ear, and the central nervous system. Nystagmus is one of the most serious eye diseases, which belongs to refractory amblyopia, and is divided into horizontal tremor and vertical tremor.

Nystagmus is caused mainly by early oculomotor dysplasia, such as congenital cataracts, which cause nystagmus, and family genetic history.

Nystagmus is a fundus disease that can affect vision in severe cases.

Most of them are congenital problems.

Nystagmus is mostly caused by developmental abnormalities and can occur after nerve damage.

1.Nystagmus is an involuntary, regular oscillation of the eyeball,** which is not yet well understood, and is mostly seen due to congenital factors, due to abnormal development of the neural structure of the cerebral cortex. Most of these patients have no self-conscious symptoms, and there are no uncomfortable symptoms such as dizziness, headache, and blurred vision.

If the abnormal sign does not interfere with the person's daily life, it can be left untreated. If there are other complications, the skull should be examined in detail for the primary disease and considered symptomatic**.

2.Nystagmus can also be seen in patients with diseases that affect vision, such as macular degeneration, congenital glaucoma, and retinitis pigmentosa, because the patient has poor vision and is unable to fix vision, so nystagmus is caused. Some neurological disorders, such as intracranial hemorrhage, can also cause nystagmus.

Nystagmus is an involuntary, rhythmic, pendulum-like or throbbing oscillation of the eyeball. In general, the main causes of nystagmus are: early oculomotor dysplasia (congenital cataract), inheritance between family members, Down syndrome, brain damage or lesions (inflammation, tumors, degeneration, trauma, vascular diseases), eye diseases or eye dysfunction (optic nerve degeneration, severe astigmatism, high myopia), physical diseases (multisite sclerosis, stroke, severe ear inflammation), poisoning (all sedatives, antispasmodics, bromide, etc.), alcoholism, albinism, etc.

Sometimes nystagmus is not defined** and may also be affected by mental or physical strength, such as stress, fatigue or nervousness.

Nystagmus can be caused by brain damage, head or motor system damage, and nystagmus has a genetic component, which may be inherited from family members.

Nystagmus**:

1.Ophthalmic nystagmus refers to visual disturbance in the center of the macula, which is caused by difficulty 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.

The symptom of nystagmus is congenital, involuntary eye swing or beating, which is an involuntary, rhythmic, back-and-forth eye movement, and the direction is divided into horizontal, vertical, and rotational types. The condition is usually congenital. Congenital nystagmus has been established as a genetic mutation.

It is not a separate disease, but a clinical manifestation of certain diseases. **In order to target**symptomatic**, reproductive intervention can be carried out through genetic testing to prevent the occurrence of nystagmus.

Nystagmus is not an independent disorder and is often a manifestation of other disorders. Nystagmus 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.

Nystagmus refers to the fact that when we normal people look at things and gaze at the target, our eyes should be fixed, staring at a target very accurately, but the nystagmus child cannot fix his eyes, and his eyes are shaking when he looks at things.
