What are the manifestations of nystagmus What are the manifestations of nystagmus?

Nystagmus is mainly manifested as rhythmic eye swing that is not controlled by the human body when staring at the target with both eyes, and the patient himself cannot feel the nystagmus, but most of them feel dizziness, dare not open their eyes, dare not move, and in severe cases, they can be accompanied by nausea and vomiting, and can also be accompanied by other autonomic manifestations such as palpitation, cold sweat, and fatigue. In addition, according to the different **, other manifestations of brainstem cerebellar damage (such as unsteady walking, difficulty swallowing, choking on drinking water, limb weakness and numbness, etc.), inner ear involvement manifestations (such as tinnitus, ear fullness, etc.), and ocular manifestations (blurred vision, diplopia, etc.).

Hello, the clinical manifestations of nystagmus are: abnormal head position, vision loss, visual stagger, dizziness, nausea, vomiting, often moving objects that do not move back and forth, and double vision tremens. Hope it helps!

According to the form of nystagmus, it is divided into horizontal, vertical and rotational nystagmus. According to the time of occurrence, it is divided into congenital and acquired nystagmus. The most common is congenital nystagmus, one of which is perceptual deficit nystagmus, also known as pendulum nystagmus.

It is often caused by congenital glaucoma, cataract, corneal leukoplakia and other anterior optic pathway diseases, and due to perceptual input disorders, resulting in incomplete control of eye movements. The other type is kinesthetic deficit nystagmus, also known as impulsive nystagmus, which is mainly in the efferent nerve pathway and may involve the nerve center, while there are no abnormal changes in the eye. There are fast and slow phases, often compensated head position, and the eyes are often in the lightest tremor position, also known as the median belt.

The involuntary flutter of the eyeballs is divided into upper and lower levels, turning in circles.

Tremor, left and right, up and down. Strabismus is lessened.

Horizontal tremor, up and down tremor, strabismus, amblyopia symptoms are all present.

Nystagmus is the side-to-side flutter of the horizontal line.

Involuntary eye fluttering comes in many forms.

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 **.

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.

Nystagmus is an involuntary, rhythmic, back-and-forth eye movement. The direction is divided into horizontal, vertical, and rotational types, with the horizontal type being the most common, and the direction of nystagmus is usually indicated in the fast-phase direction.

For example, jumping up and down, turning left and right.

Impulsive nystagmus is two rhythmic in which the eyeball moves at an uneven speed to both sides, turning on the slow side, and then rapidly rotating in the opposite direction. The fast phase is generally used as the direction of nystagmus.

Wobbly nystagmus is when the eye moves from the midpoint to the sides, with the same amplitude and speed of movement, and there are no fast or slow phases.

2.In the direction of tremor, nystagmus is characterized by horizontal, vertical, rotational, inclination and miscellaneous, among which horizontality is the most obvious.

3.Nystagmus frontal self-consciousness symptoms are generally not self-conscious due to the lack of development of the fixation reflex, and acquired people will also have self-conscious symptoms in adulthood.

1) Vision loss due to macular dysplasia or due to tremor that is not conducive to the fixation of the macula, and the fixation reflex cannot develop.

The main manifestation of nystagmus is uncontrollable eye movement, but the form, direction, amplitude and speed of binocular movement will vary from patient to patient, and may be accompanied by vision loss, object shaking, and diplopia.

and other symptoms.

There are two types of clinical manifestations of nystagmus: throbbing and oscillating. The beating type is that the eyeball moves back and forth with a clear difference in speed, and when the eye slowly turns to a certain direction, it suddenly returns in a rapid movement.

1. Beating type: the eyeball is in a reciprocating movement with obvious different speeds, and when the eyeball slowly turns to a certain direction, it suddenly returns with a rapid jumping movement. Therefore, this tremor has the manifestation of chronic and pleasant phase, chronic is the physiological phase, fast phase is the corrective movement of the slow phase, and 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, and there is no fast phase and slow phase. Its velocity and amplitude are equal. It is more common in patients with dark eyes and amblyopia.

3. Forms of tremorThere are two forms of nystagmus: impulsive and swinging.

Impulsive nystagmus is birhythmic and involves the movement of the eyes in both directions at unequal speeds, turning slowly to one side and then in the opposite direction of the fast phase. Usually the fast phase is used as the direction of nystagmus. Oscillatory nystagmus is the movement of the eye from the midpoint to the sides of the globe with equal amplitude and velocity, and there is no distinction between fast and slow.

4. The direction of tremor The direction of nystagmus is horizontal, vertical, rotatory, oblique and mixed, among which the horizontal type is the most common.

5. Conscious symptoms of nystagmus, congenital patients have no conscious symptoms because the fixation reflex has not yet developed; Acquired people may develop self-conscious symptoms in adulthood.

Nystagmus has become a disease with a relatively high incidence in ophthalmology, which is said to be caused by genetics or vision loss. Patients will show many symptoms, and only timely medical attention can be relieved.

1. Vision loss: Patients will show blurred vision, which mainly refers to lower visual acuity. Vision loss can be restored by methods such as distant gaze, lens exercises, and manipulations.

The distant gaze consists of a full-body gaze for 25 seconds, recognizing the outlines of blades of grass and leaves. The exercise is done by using both hands to rotate the eyeballs in order.

2. Compensatory head position: In order to see objects clearly, patients use some special head positions such as eccentricity and side face to overcome the discomfort of seeing, and sometimes they will be accompanied by involuntary shaking or nodding. This condition can be corrected by wearing glasses.

If the effect of wearing correction is not obvious, it needs to be performed by surgery**.

3. Shaking of objects: patients will have a sense of turbulence, dizziness, nausea and vomiting when looking at external objects, and often feel that immobile objects are constantly moving back and forth. Brain MRI is usually done, and most of them may be caused by insufficient blood supply.

Minimize external disturbances to objects, such as air currents or vibrations. The patient is horizontal, and can hang objects and pull a few more lines around it.

Nystagmus is mostly caused by neuromuscular dysplasia of the eye or cataracts, total color blindness, etc. In some patients, it is caused by ocular nystagmus or central nystagmus or otogenic nystagmus. Patients will show some of the above symptoms, but in addition to brain tumors, cerebrovascular diseases and other symptoms.

Patients with nystagmus mainly manifest themselves as uncontrollable eye movements, but different patients will have different eye movement forms, directions, amplitudes and speeds, and may be accompanied by abnormal head position, vision loss, refractive error, vertigo, diplopia and other symptoms.

1. Typical symptoms.

1. Uncontrollable eye movements: patients are unable to move their eyes voluntarily.

2. Double vision: refers to the abnormal phenomenon that when two eyes look at an object, they feel like two objects.

3. Strabismus: It means that both eyes cannot focus on the target at the same time.

4. Vision loss: Vision is mostly used to distinguish small or distant objects, and vision below is vision loss.

5. Abnormal light adaptation and dark adaptation: some patients may be sensitive to bright light or difficult to see in dark places.

6. Shaking of objects: when looking at external objects, there is a sense of turbulence, dizziness, nausea, vomiting, and often feeling that the objects that do not move are constantly moving back and forth.

7. Compensatory head position: In order to see objects clearly, special head positions such as eccentric head and side face are used to overcome the discomfort of seeing, sometimes accompanied by involuntary shaking or nodding.

2. Accompanying symptoms.

1. Oculogenic nystagmus may be accompanied by visual impairment, refractive error, and diplopia.

2. Otogenic nystagmus may be accompanied by vertigo, tinnitus, earache, ear swelling, etc.

3. Central neurogenic nystagmus may be accompanied by headache, ataxia, nausea, vomiting, etc.

Symptoms of nystagmus include:

1.decreased vision;

2.Involuntary oscillation or throbbing of the eyeball: the eyeball moves back and forth at a marked different speed, and when the eye slowly turns in the other direction to reach a certain level, it suddenly returns in a sharp movement;

3.The patient's compensatory cephalic position: the patient's head is tilted to see, and the compensatory cephalic position is corrected through surgery, so as not to lead to abnormal spinal development and facial asymmetry in children.

It usually presents with a sense of movement, vision loss, central nystagmus on retest, congenital essential nystagmus, and central nystagmus.

The eyeball will move 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 motion.

Nystagmus, or nystagmus for short, is a serious eye disease in which the patient sees things shakingly and cannot be fixed at one point. Its main symptoms are as follows: eyeball twitching or wiggling:

Involuntary, persistent, and more regular eye beats or movements in both eyes or in one eye. Jumping - The eyeball moves back and forth at a marked different speed, and when the eye slowly turns in the other direction to reach a certain point, it suddenly returns in a rapid motion. Swing type – The swing of the eyeball is the same as that of a pendulum.

Compensatory cephalic position: mainly manifested as the left and right deflection of the face, only a few are the upward or inward lifting or adduction of the lower collar, and the left and right tilt of the head. Vision loss, amblyopia:

Nystagmus can significantly affect the perception of depth of vision (i.e. the ability to distinguish the distance of objects), resulting in decreased vision. This adversely affects the normal visual development of children, resulting in more severe amblyopia. Sense of object movement:

There is a sense of turbulence when looking at external objects, dizziness, nausea, vomiting, and often the sensation of moving objects that are not moving back and forth. Diplopia: central nystagmus is more likely to have tremor diplopia.

Those with the above symptoms should go to a regular specialist hospital for treatment in time for relevant examinations and **.

1.Nystagmus is the uncontrolled back and forth swing or beating of the eyeball, as the main symptom, different types, different types of nystagmus are also different, among which the hidden nystagmus, the symptoms are relatively special, not easy to be detected, need to cover the examination or other instrument detection, can be clear. In some patients, the eyeballs flutter like a pendulum, and the left and right sides are noticeably shaking.

2.Nystagmus is mostly associated with lesions of the neuromuscular system, and in addition to ocular symptoms, patients may also have blurred vision, compensatory headache, dizziness, vertigo, vomiting, nausea and other manifestations.

The eyeballs will unconsciously sway from side to side.

Because the fixation reflex is not yet developed, patients with congenital nystagmus are generally asymptomatic; Patients with acquired nystagmus may develop self-conscious symptoms in adulthood. uncontrollable eye movements; vision loss; The feeling of shaking objects, the feeling of turbulence when looking at external objects, dizziness, nausea, vomiting, and often feeling that objects that do not move back and forth are constantly moving; Diplopia; Compensatory head position, that is, in order to see objects clearly, some special head positions such as eccentric head and side face are used to overcome the discomfort of seeing, sometimes accompanied by involuntary shaking or nodding; Strabismus; Some people may be sensitive to bright light or have difficulty seeing in dark places.

Nystagmus: The most typical symptom is that the patient's eye moves uncontrollably and rhythmically at regular intervals. When the patient opens or closes one eye, the nystagmus oscillates at the same amplitude and frequency, often oscillating from side to side like a pendulum.

Or when the eyes are opened, there is no nystagmus, the eyes are covered, and the eyes swing when they are opened again.

1. Retinal or refractive media lesionsThese lesions often cause cataracts, refractive errors, choroiditis, and some patients will suffer from the disease at an early age, although they will have amblyopia symptoms, but still preserve their vision, and these patients often cannot fix the fixation of the eyeball, and then develop nystagmus symptoms. If the patient is in a poor light environment for a long time, he will also have vision fixation disorder and wobble tremor. 2. Vestibular labyrinth lesionsIf a patient has damage to the vestibular nerve or vestibular nerve nucleus, the vestibular nerve response will be too high or too low, and these adverse symptoms can cause nystagmus.

Acute vestibular labyrinth lesions cause contralateral tremor of the eyeball, accompanied by tinnitus, nausea and vomiting. If the labyrinth lesion is chronic, the patient will tremor toward the affected side.

Symptoms of nystagmus mainly include eye-punching or wiggling, which is an involuntary, continuous, and more regular eye-punching or swinging of the eye or monocular, with the eyeball moving back and forth at a marked rate. When the eyeball slowly turns in the other direction to a certain point, it suddenly returns with a sharp jump, and the eye swings in the same way as the pendulum.

There are two types of nystagmus, throbbing and oscillating. Throbbing nystagmus is a reciprocating movement of the eyes at a marked difference in velocity, when the eyes slowly turn in the other direction to a certain extent, and then suddenly return in a rapid motion. This type of tremor has the manifestations of slow phase and fast phase, the slow phase is the physiological phase, and the fast phase is the corrective movement of the slow phase.

Oscillatory nystagmus is when the eye swings like a pendulum, with no fast or slow phases, and its speed and amplitude are equal.
